The occupancy rate of a hotel is the share of available rooms that are occupied during a given time. Figure- I presents quarter wise average hotel occupancy in four regions (Asia-Pacific, America, Europe and Middle East & Africa) for the year 2016. Figure-2, shows the revenue of select hotel chains worldwide in 2016.
Figure-1: Region Wise Average Hotel Occupancy Rates
Occupancy rates
Regions $$\rightarrow$$
Considering the total revenue of the hotel industry in 2016 as 495.17 billion USD. what is the percentage contribution of revenue of select hotel chains to hotel industry revenue?
Required percentage = $$\ \ \ \frac{\ 24+16+12+6+6+4.5+2+0+0+0}{495.17}\times\ 100=\frac{70.5}{495.17}\times\ 100=14.23\%$$
The answer is option B.
For Hilton Worldwide, considering 70% average occupancy rate for 365 days of operations and average room rent of 350 USD per day, the total number of rooms available (in 000's) in Hilton Worldwide per day approximately are:
From the graph, the total revenue of Hilton worldwide is 12 billion dollars.
We are told that the room rent per day = 365 USD
Let the total number of rooms available be 'T'. We are also told that occupancy is 70%. So, the occupied rooms on any day are $$\frac{70}{100}T$$
$$\frac{70}{100}T\times\ 365\times\ 350=12\times\ 10^9$$
Solving, we get T = 134,190
In thousands, it will be 134.
The closest option is option B. Hence, the answer is option B.
If the number of available rooms in each of the four regions (Asia-Pacific, America, Europe and Middle East & Africa) are in the ratio 1:2:5:4, the average occupancy rate for Quarter-1 are:
Let the rooms available in different regions be x, 2x, 5x and 4x. The occupancy rates in the 4 different regions in the Quarter 1 are given as 67, 60, 61 and 64. The average occupancy rate can be calculated as,
Average occupancy rate = $$\ \ \dfrac{\ 67\left(x\right)+60\left(2x\right)+61\left(5x\right)+64\left(4x\right)}{x\ +\ 2x\ +\ 5x\ +\ 4x}=\dfrac{748x}{12x}=62.3$$
The answer is option A.
Assuming that there is no change in the number of available rooms in a given year in all four regions, the correct arrangement in the increasing order of average annual occupancy rates is :
Average annual occupancy rate of Asia Pacific = $$\ \frac{\ 67+68+72+71}{4}=\frac{278}{4}=69.5$$
Average annual occupancy rate of America = $$\ \frac{\ 60+69+61+71}{4}=\frac{261}{4}=65.25$$
Average annual occupancy rate of Europe = $$\ \frac{\ 74+69+61+78}{4}=\frac{282}{4}=70.5$$
Average annual occupancy rate of Middle East and Africa = $$\ \frac{\ 64+58+61+63}{4}=\frac{246}{4}=61.5$$
Increasing order - Middle East and Africa, America, Asia Pacific and Europe
The answer is option B.

GBS - 18220 + 19280 + 18570 + 18400 + 17800 + 17160 + 16700 + 16350 = 142480 - 2nd
SYS - 9550 + 7710 + 8190 = 25450
GF - 2240 + 2100 + 2010 + 2020 + 2000 + 1840 + 1690 +1700 = 15600
Others - least - 3710
SOFT - 22490 + 24940 + 25450 + 25930 + 25400 = 124210 - 3rd
GTS - 38200 + 40880 + 40240 + 38550 + 37100 = 194970 - 1st
S&T - 17970 + 18990 + 17670 + 14370 + 10000 = 79000
Software has earned third highest cumulative revenue in the time period 2010-2017.
The answer is option B.
The profit booked by IBM in year 2012 is USD 49 billion. Considering equal percentage profit margins across all segments, then approximate profit made by 'Systems and Technology' in millions USD is
Revenue in 2012 = 18570 + 2010 + 580 + 25450 + 40240 + 17670 = 104520 = 104.52 billion
Profit % = $$\frac{49}{104.52-49}\times\ 100\ =\ 88.26\%\ $$
Let the profit made by Systems and Technology in 2012 be 'x'
$$\frac{x}{17670-x}=\frac{49}{55.52}$$
x = 8283.87

An agent has to send a secret message to CBI office in Delhi. He needs to compile his message using following 12 code words- Scare, Logical, Mouse, Beauty, Helping, Roses, Cats, Doctor, Arguments. Crude. Ferry and Mineral. The agent compiles the coded message and delivers it to CBI office in form of a $$4\times3$$ matrix. Each coded word has been allocated a position in the matrix ($$1\times2$$ position represents row 1 and column 2). The clues to compile the secret message are:
i. The words in $$2\times1$$ and $$3\times1$$ have the same number of letters.
ii. Roses is to the immediate left of Beauty and Mineral is immediately above Roses.
iii. The word in $$4\times3$$ is shorter than the word in $$1\times2$$.
iv. Ferry is separated from Helping horizontally by only one word Logical.
v. Arguments is at position $$2\times3$$ in the matrix and the word immediately below it has odd number of letters.
vi. Crude and Doctor are in the same horizontal row and Crude is to the right of Doctor.
vii. Cats is not in the same row or column as Mouse.
The product of the position of a coded word is 8. Identify the word.
In statement 2 it is given that Roses is to the immediate left of Beauty and Mineral is immediately above Roses.
In statement 4 it is given that Ferry is separated from Helping horizontally by only one word Logical.
In statement 6 it is given that Crude and Doctor are in the same horizontal row and Crude is to the right of Doctor. They can be arranged in three ways in a horizontal row.
It is given that Arguments is at $$2\times\ 3$$ position.
There are three cases possible. Mineral, roses and beauty placed at positions (a,b,c), (d,e,f) and (p,f,r).
Case 1: Mineral, roses and beauty at (d,e,f)
In statement 1 it is mentioned that the words in $$2\times1$$ and $$3\times1$$ have the same number of letters. Mineral has 7 letters. There are no remaining words with 7 letters. Therefore, this case is not possible.
Case 2: Mineral, roses and beauty at (p,f,r)
Doctor must be placed at either $$2\times1$$ or $$3\times1$$. Doctor is a 6 letter word and there is no word with 6 letters to be placed at the alternate position. Therefore, this case is not possible.
Case 3: Mineral, roses and beauty at (a,b,c)
Placing ferry, helping and logical in fourth row will not give valid arrangement. Therefore,
Remaining words are cats, doctor, crude, mouse and scare.
The number of letters in $$4\times3$$ should be less than $$1\times2$$. Doctor cannot be placed in row 1. Therefore, a five letter word is placed at $$1\times2$$ and four letter word placed at $$4\times3$$.
Final arrangement:
The only possible position whose product is 8 is $$4\times\ 2$$. The word at $$4\times\ 2$$ is crude.
The answer is option A.

There are three cases possible. Mineral, roses and beauty placed at positions (a,b,c), (d,e,f) and (p,f,r).
Case 1: Mineral, roses and beauty at (d,e,f)

In statement 1 it is mentioned that the words in $$2\times1$$ and $$3\times1$$ have the same number of letters. Mineral has 7 letters. There are no remaining words with 7 letters. Therefore, this case is not possible.
Case 2: Mineral, roses and beauty at (p,f,r)

Doctor must be placed at either $$2\times1$$ or $$3\times1$$. Doctor is a 6 letter word and there is no word with 6 letters to be placed at the alternate position. Therefore, this case is not possible.
Case 3: Mineral, roses and beauty at (a,b,c)
Placing ferry, helping and logical in fourth row will not give valid arrangement. Therefore,

Remaining words are cats, doctor, crude, mouse and scare.
The number of letters in $$4\times3$$ should be less than $$1\times2$$. Doctor cannot be placed in row 1. Therefore, a five letter word is placed at $$1\times2$$ and four letter word placed at $$4\times3$$.

A consultant to Department of Commerce. Government of Bianca has suggested 30 products which have high export potential. Dora an entrepreneur and prospective exporter notices that these products can be grouped in three ways- Machine made goods, Handmade goods and Intermediate goods. Among these 30 products some products are both machine made and intermediate goods but not handmade goods. Few products have a combination of handmade and machine made goods but not intermediate goods. Some products are handmade and intermediate goods but not machine made goods. Further it is seen that handmade-machine made goods are I less than machine made-intermediate goods. Similarly the total number of handmade-intermediate goods is I less than machine made-intermediate goods. There are just 4 products common across all product groups i.e. machine made-handmade- intermediate goods. Apart from this the number of only handmade goods is same as only machine made goods but less than only intermediate goods. Each product group/combination has at least one product. Dora prefers to export machine made goods and avoid hand made goods. She finds out that only handmade goods are twice the only machine made-intermediate goods and the number of only intermediate goods is an even number. Whereas her close friend Sara prefers to export intermediate goods followed by only handmade goods.
Sara and Dora prefer to export as many common products as possible in order to understand the regulatory conditions. Keeping their preferences intact, what is the maximum number of common products which can be exported by both of them?
It is given, y = 2x
z > y and z is even
y = 2x
2y + 3x + z + 2 = 30
7x + z = 28
Only x = 2 and z = 14 satisfies the given conditions.
Maximum common products both Dora and Sara can export = Products common to Machines and Intermediates only = x = 2
The answer is option A.
If another exporter Abeer prefers to export only intermediate goods, then the total number of products which both Abeer and Dora export are

It is given, y = 2x
z > y and z is even
y = 2x
2y + 3x + z + 2 = 30
7x + z = 28
Only x = 2 and z = 14 satisfies the given conditions.
The total number of products which both Abeer and Dora export = Intermediate + Machine - Homemade = 14 + 2 + 4 = 20
The answer is option B.

PASSAGE 1
We use the word culture quite casually when referring to a variety of thoughts and actions. I would like to begin my attempt to define cultures by a focus on three of its dictionary meanings that I think are significant to our understanding of the general term-culture. We often forget that it's more essential usage is as a verb rather than as a noun, since the noun follows froth the activities involved in the verb. Thus the verb, to culture, means to cultivate. This can include at least three activities: to artificially grow microscopic organisms; to improve and refine the customs, manners and activities of one's life; to give attention to the mind as part of what goes into the making of what we call civilization, or what was thought to be the highest culture. In short, one might argue that culture is the intervention of human effort in refining and redefining that which is natural, but that it gradually takes on other dimensions in the life of the individual, and even more in the interface between the individual and society. When speaking of society, this word also requires defining. Society, it has been said, is what emerges from a network of interactions between people that follow certain agreed upon and perceptible patterns. These are determined by ideas of status, hierarchy and a sense of community governing the network. They are often, but not invariably, given a direction by those who control the essentials in how a society functions, as for instance, its economic resources, its technology and its value systems. The explanation and justification for who controls these aspects of a society introduces the question of its ideology and often its form.
The resulting patterns that can be differentiated from segment to segment of the society are frequently called its cultures. Most early societies register inequalities, The access of their members to wealth and status varies. The idea of equality therefore has many dimensions. All men and women may be said to be equal in the eyes of god, but may at the same time be extremely differentiated in terms of income and social standing, and therefore differentiated in the eyes of men and women. This would not apply to the entire society. There may be times when societies conform to a greater degree of equality, but such times may be temporary. It has been argued that on a pilgrimage, the status of every pilgrim is relatively similar but at the end returns to inequalities. Societies are not static and change their forms and their rules of functioning. Cultures are reflections of these social patterns, so they also change. My attempt in this introduction is to explain how the meaning of a concept such as culture has changed in recent times and has come to include many more facets than it did earlier. What we understand as the markers of culture have gone way beyond what we took them to be a century or two ago. Apart from items of culture, which is the way in which culture as heritage was popularly viewed, there is also the question of the institutions and social codes that determine the pattern of living, and upon which pattern a culture is constructed. Finally, there is the process of socialization into society and culture through education. There is a historical dimension to each of these as culture and history are deeply intertwined. There is also an implicit dialogue between the present and the past reflected in the way in which the readings of the past changed over historical periods.
Every. society has its cultures, namely, the patterns of how the people of that society live. In varying degrees this would refer to broad categories that shape life, such as the environment that determines the relationship with the natural world, technology that enables a control over the natural world, political-economy that organizes the larger vision of a society as a community or even as a state, structures of social relations that ensure its networks of functioning, religion that appeals to aspirations and belief, mythology that may get transmuted into literature and philosophy that teases the mind and the imagination with questions. The process of growth is never static therefore there are mutations and changes within the society. There is communication and interaction with other societies through which cultures evolve and mutate. There is also the emergence of subcultures that sometimes take the form of independent and dominant cultures or amoeba-like breakaway to form new cultures. Although cultures coincide with history and historical change, the consciousness of a category such as culture, in the emphatic sense in which the term is popularly used these days, emerges in the eighteenth century in Europe. The ideal was the culture of elite groups, therefore sometimes a distinction is made between what carne to be called 'high culture' that of the elite, and low culture' that of those regarded as not being of the elite, and sometimes described as 'popular'. Historical records of elite cultures in forms such as texts and monuments for instance, received larger patronage and symbolized the patterns of life of dominant groups. They were and are more readily available as heritage than the objects of the socially lower groups in society whose less durable cultural manifestations often do not survive. This also predisposed people to associate culture as essentially that of the elite.
What is the central idea of the passage?
The author explains cultural metamorphosis in different context.
He then attempts to introduce the different facets of cultural metamorphosis and explains them in different contexts.
Hence, the correct answer is option D
According to the author what are the characteristics of 'Society'?
"Society, it has been said, is what emerges from a network of interactions between people that follow certain agreed upon and perceptible patterns. These are determined by ideas of status, hierarchy and a sense of community governing the network. They are often, but not invariably, given a direction by those who control the essentials in how a society functions, as for instance, its economic resources, its technology and its value systems."
From the above lines, it is clear that option B is the correct answer.
Option A: The passage mentions inequalities in society, such as differences in wealth and social standing, but it doesn’t define society solely on the presence of "rich and poor."
Option C: While the passage discusses inequalities and how some individuals have more control over resources (such as economic power, technology, etc.), it does not define society solely in these terms.
Option D: This is just an example and not what defines society as per the passage.
With reference to the above passage, what are the important elements of 'Culture'?
"Every. society has its cultures, namely, the patterns of how the people of that society live. In varying degrees this would refer to broad categories that shape life,"
"There is a historical dimension to each of these as culture and history are deeply intertwined. There is also an implicit dialogue between the present and the past reflected in the way in which the readings of the past changed over historical periods."
Consider the above two lines. It can be inferred from these lines that option C is the correct answer.

PASSAGE 2
Today, we have specialists in various professions, but many among them are unconcerned with the world beyond their own specialization. It is sometimes said that they arc replacing the public intellectual. But the two are not identical. There are many more academics, for instance, than existed before. But it seems that most refer not to confront authority even if it obstructs the path of free thought. Is this because they wish to pursue knowledge undisturbed, or because they are ready to discard knowledge should authority require them to do so? Or does association with national or international agencies require that critical assessments of social thought and action remain sotto voce? Today, as always, he public intellectual is expected to take a position independent of those in power, enabling him or her to question debatable ideas, irrespective of who propagates them. Reasoned critiques are often the essential starting point. The public intellectual has to see himself or herself as a person who is as close to being autonomous as is possible, and more than that, be seen by others as such.
An knowledged professional status makes it somewhat easier to be autonomous. Such status brings with it another kind of authority, conceded, even if grudgingly, by professional peers and this does make some small impact on the non-professional world. The public intellectual of today, in addition to being of such a tatus, has to have at the same time a concern for what constitutes the rights of citizens. particularly on issues of social justice, and further, there should be a readiness to raise these matters as public policy. The combination of drawing upon the professional respect that a person has garnered, together with a concern for society, can sometimes establish the moral authority of that person and ensure public support. This is a conceded qualification and not a tangible one. In the past it was those who had distanced themselves somewhat from society who were believed not to have a vested interest in the changes they were suggesting. Although this was not always so, we know that close associations, such as formal affiliation to a political party, can inhibit free-thinking and criptions for action, even if it has the advantage of providing a certain leverage to the suggestions being ade. As an attitude of mind, autonomy is more readily expected of the professional specialist or the demic. Such persons, and they are not the only ones, can suggest alternative ways of thinking, even about ems of the larger society. Their thinking should emerge from reasoned, logical analyses. Yet academics today are hesitant to defend even the right to make what might be broadly called alternative, if not rational interpretations, however sensitively they may be xpressed. This is evident from the ease with which books arc banned and pulped, or demands made that they be burned, and syllabuses changed under pressure from religious or political organizations, or the intervention of the state. Why do such actions provoke so little reaction among many academics and professionals? The answer that is usually given is that they fear the instigators who arc persons with the backing of political authority. But is this the only answer?
Is it assumed that opinions about governance and society must hinge on ideologies linked to political parties and as a result there can be no thinking about how to configure society in a manner that is independent of a necessary commitment to political parties? Surely in this day and age, it is possible to he an independent liberal in this country with ideological commitments that arc not determined solely by political parties? Being a liberal is an attitude of mind that determines the fight for space in a society when that society resists ethics and reasoned thinking. The understanding of what one is battling for assumes an ideological direction but this does not require association with a political party. And there should also be the freedom to choose one's position on an issue and this position need not be in conformity with the ideological take of a particular political party on every occasion. The public intellectual has, by definition, to be liberal, that is, to insist that there be space to present varying perspectives and that wherever possible, reason and ethics should have primacy in whatever debates are taking place. This is not a new definition and has been a recognizable part of the interface between knowledge and society since earliest times. Approximations to orthodoxy and orthopraxy have always been contested by similar approximations to heterodoxy although those leading the charge do not always have or need to have the same social identity. This is apparent among people and situations in the Indian past yet we have often ignored it or failed to recognize it. How an intellectual even without being a public intellectual, requires a more than average knowledge in his/her professional specialization and beyond that a familiarity with the context of that knowledge: how did it come about and what arc the implications for the people who use that knowledge. To be a technician (or be technically accomplished) in a specialization, however good, is not sufficient. An intellectual perspective requires that the specialized knowledge one possesses should be related to social concerns where required and to other branches of knowledge as well. Added to this it helps if that knowledge can be contextualized in an accessible way for a wider range of people to understand facets of the variegated world in which we live, and to which understanding the specialization contributes. The public intellectual uses such foundations in his/her thinking in order to extend the understanding of the world we inhabit, and to do so by insisting on space for debate and the right to informed opinion.
According to the author, 'Public Intellectual' is one who
In third paragraph, it is given 'the public intellectual has, by definition, to be liberal, that is, to insist that there be space to present varying perspectives and that wherever possible, reason and ethics should have primacy in whatever debates are taking place.' Option B is the appropriate answer.
The answer is option B.
How does the author differentiate between Public Intellectuals of the past and today?
The author thinks that public thinkers in the past were seen as more independent and likely to speak their minds. But today, public thinkers (like academics) might be more worried about getting in trouble with people in power, so they might not speak as freely.
The answer is option D.
With reference to the above passage, explain the relationship between Orthodoxy, Orthopraxy and Heterodoxy as proposed by the author as applicable to the Public Intellectual'
orthodox - following or conforming to the traditions and beliefs of particular religion or philosophy (lack of other knowledge)
orthoprax - an intellectual perspective, the one who posses knowledge to social concerns as well.
heterodox - the one who expands his sphere to external world
Heterodoxy matches with author's idea on public intellectual. The answer is option B.

PASSAGE 3
We love information. Especially in times of crisis. Have you ever noticed your tendency to become glued to the television or Internet when disaster strikes? It is human nature to try to gather as much information as possible, to make sense and create meaning when we don't understand what is happening. We seek information for another reason too, control. We operate under the illusion that if we can gain more information, we will not only understand what is happening, we might just be able to control it. I am not suggesting that there is no value to information or to clearly defined reporting and accountability relationships for routine business operations. I am instead calling out the temptation that an information-centred approach to agility offers: there's a desire to settle into the illusion that information will give you control, when in many situations it is simply not possible to gather or process enough information to be effective when it counts.
Recognizing that there are many situations that you not only cannot control but cannot predict is a radical mind-set and practice shift for most. It requires that you decide whether your goal is to reduce the perception of uncertainty or to actually become more effective in its midst. It also involves more than a simple reconfiguration of the organisation chart and job descriptions. It require relinquishing the illusion of control that lies at the very foundation of most management training and business practice. This shift is being made in one of the most hierarchal, command-and-control organizations in the country, the United States military. Recognizing the insidious nature of information age strategies and their tendency to lead to either analysis paralysis or the false security of convenient stories, the U.S. military has begun to make a fundamental shift in its approach to VUCA (volatility, uncertainty, complexity, and ambiguity), a shift from information to interactions. This change does not begin with restructuring and redeployments but with a fundamental shift in mind-set. In fact, the term. VUCA was first coined by the U.S. Army War College to describe increasingly complex and unpredictable combat conditions." VUCA has become shorthand for the reality of life in the twenty-first century. Most business approaches to VUCA focus on strategies to reduce
uncertainty. These strategies tend to centre around gaining greater control, including amassing more and better information, minimizing risk, and improving planning and analysis. While risk and uncertainty reduction are valid strategies, they do not necessarily make an organization more agile, for two reasons: ( 1) collecting more and better information takes time and may foster the illusion of control and comfort when, in reality, it is impossible to gather all available information in complex, changing contexts, let alone fully analyze and make meaning of, it and (2) planning and analysis are dependent on relatively stable contexts. Another liability of information-centred approaches is that they typically lead to more questions and the need to gather more information to reduce the uncertainty created by the information already collected. There is an even more significant liability of the information-centred approach to agility: our preconceptions lead us to filter out information that does not align with our expectations. Under the stress of an unexpected challenge or opportunity, our ability to access our higher thinking capacity can be reduced, leading us to fall back on the version of the story we expected. Warnings of terrorist threats before 9/11 and potential malfunctions of crucial components prior to the Challenger space shuttle disaster went unheeded because they did not fit the narrative that was co-constructed by leaders during years of experience and expectation. Agile leaders, teams and organizations know they cannot afford to get caught up in a story. They arc
instead learning how they might be more effective by focusing on their interactions with one another and with the available information in the dynamic present moment.
Let me emphasize that this is a shift away from an overreliance on information. I am not suggesting you curtail important industry and market data analysis, or take this as encouragement to blindly make decisions when further investigation is warranted. I am encouraging you to shift away from the false comfort such information can offer, and toward the relational context in which you make sense of it, decide and act. When we make the shift from information to interaction, we may be called to shift more than our relationship to external information; we may need to shift the way we perceive ourselves as well. The agility shift requires that we value our capacity to connect and build relationships over-or at least as much' as-our hard-won expertise. Years of experience, training and credentials are, of course, still valuable. But their value is minimal without the networks to which the skills, knowledge, experience, and resource awareness are linked. In other words, separating the process of "knowing what" and "knowing how" from the process of "knowing who" significantly diminishes agility capacity. The shift from information to interaction values the human system in which all meaning and action take place. Rather than problematizing this system as non-objective or messy, the agility shift embraces it and engages it more fully. You may not be able to control or predict what happens. but with a conscious, continuous commitment to interacting within your web of relationships and resources, you will be more effective than you ever imagined. The agility shift is first and foremost a shift in mind-set. This mind-set values interactions within the dynamic present moment. It is also a shift from the false comfort of "a plan" to achieving a state of readiness to find opportunity in the unexpected.
With reference to the above passage what is the author's stand with regard to Information'?
The third paragraph it is mentioned that there is an over reliance on information leading to complacency in decision making. Option D captures the point mentioned in the passage. Option C is contradictory. Option A is partially correct, author also mentions that there need to be a shift in our thoughts and actions. Option B is incorrect as it says information is important. The answer is option D.
According to the author what causes 'analysis-paralysis"?
In second paragraph it is mentioned that how today's leaders have more information and spend time on analysing the information instead of reacting. Options B captures the point mentioned in the passage. The answer is option B.
With reference to the above passage, 'agility shift' is
In second and thirds paragraphs, author clearly mentions the shift required from information to interaction to take effective decisions. In third paragraph, author also mentions that the agility shift requires that we value our capacity to connect and build relationships over-or at least as much' as-our hard-won expertise. Therefore, the answer is option C.
According to the author, why do we 'love' information?
In first paragraph, it is mentioned that we operate under the illusion that if we can gain more information, we will not only understand what is happening, we might just be able to control it. Among the given options, option C is the most appropriate one.
The answer is option C.

PASSAGE 4
While majoring in computer science isn't a requirement to participate in the Second Machine Age, what skills do liberal arts graduates specifically possess to contribute to this brave new world? Another major oversight in the debate has been the failure to appreciate that a good liberal arts education teaches many skills that are not only valuable to the general world of business, but are in fact vital to innovating the next wave of breakthrough tech-driven products and services. Many defenses of the value of a liberal arts education have been launched, of course, with the emphasis being on the acquisition of fundamental thinking and communication skills, such as critical thinking, logical argumentation, and good communication skills. One aspect of liberal arts education that has been strangely neglected in the discussion is the fact that the humanities and social sciences are devoted to the study of human nature and the nature of our communities and larger societies. Students who pursue degrees in the liberal arts disciplines tend to be particularly motivated to investigate what makes us human: how we behave and why we behave as we do. They're driven to explore how our families and our public institutions-such as our schools and legal systems-operate, and could operate better, and how governments and economies work, or as is so often the case, are plagued by dysfunction. These
students learn a great deal from their particular courses of study and apply that knowledge to today's issues, the leading problems to be tackled, and various approaches for analyzing and addressing those problems.
The greatest opportunities for innovation in the emerging era are in applying evolving technological capabilities to finding better ways to solve human problems like social dysfunction and political corruption; finding ways to better educate children; helping people live healthier and happier lives by altering harmful behaviors; improving our working conditions; discovering better ways to tackle poverty; Improving healthcare and making it more affordable; making our governments more accountable, from the local level up to that of global affairs; and finding optimal ways to incorporate intelligent, nimble machines into our work lives so that we are empowered to do more of the work that we do best, and to let the machines do the rest. Workers with a solid liberal arts education have a strong foundation to build on in pursuing these goals. One of the most immediate needs in technology innovation is to invest
products and services with more human qualities. with more sensitivity to human needs and desires. Companies and entrepreneurs that want to succeed today and in the future must learn to consider in all aspects of their product and service creation how they can make use of the new technologies to make them more humane. Still, many other liberal arts disciplines also have much to provide the world of technological innovation. The study of psychology, for example, can help people build products that are more attuned to our emotions and ways of thinking. Experience in Anthropology can additionally help companies understand cultural and individual behavioural factors that should be considered in developing products and in marketing them. As technology allows for more machine intelligence and our lives become increasingly populated by the Internet of things and as the gathering of data about our lives and analysis of it allows for more discoveries about our behaviour, consideration of how new products and services can be crafted for the optimal enhancement of our lives and the nature of our communities, workplaces and governments will be of vital importance. Those products and services developed with the keeneSt sense of how they' can serve our human needs and complement our human talents will have a distinct competitive advantage. Much of the criticism of the liberal arts is based on the false assumption that liberal arts students lack rigor in comparison to those participating in the STEM disciplines and that they are 'soft' and unscientific whereas those who study STEM fields learn the scientific method. In fact the liberal arts teach many methods of rigorous inquiry and analysis, such as close observation and interviewing in ways that hard science adherents don't always appreciate. Many fields have long incorporated the scientific method and other types of data driven scientific inquiry and problem solving. Sociologists have developed sophisticated mathematical models of societal networks. Historians gather voluminous data on centuries-old household expenses, marriage and divorce rates, and the world trade, and use data to conduct statistical analyses, identifying trends and contributing factors to the phenomena they are studying. Linguists have developed high-tech models of the evolution of language, and they've made crucial contributions to the development of one of the technologies behind the rapid advance of automation- natural language processing, whereby computers are able to communicate with the, accuracy and personality of Siri and Alexa. It's also important to debunk the fallacy that liberal arts students who don't study these quantitative analytical methods have no 'hard' or relevant skills. This gets us back to the arguments about the fundamental ways of thinking, inquiring, problem solving and communicating that a liberal arts education teaches.
What is the central theme of the passage?
Option A captures the main point of the passage, i.e. STEM skills and social liberal skills both are required to develop products which are most relevant today. Option B and C do not consider social liberal skills. Option D is too extreme by saying can solve all the problems. The answer is option A.
How can companies gain an edge in today's era of technological innovation?
Option C best captures the point mentioned in the passage. In the passage, nowhere it is discussed about the price of products. Therefore, option B is incorrect.
Option A did not mention the point on how products should help to deal with variety of social problems.
In the passage, nowhere it is mentioned that products should be similar to human beings.
Hence, the answer is option C.
What is the author's opinion with regard to the contribution of students of liberal arts and those of STEM, in this new technological age?
The author thinks that people who study things like history, literature, and social sciences (liberal arts) are really good at understanding people. This helps them make technology that actually fits what humans need and want. People in science and technology fields (STEM) are great at building the technology, but the liberal arts folks are key to making it feel more human.
Options A and C are clearly incorrect. Option B is incorrect because the author gives examples where liberal arts students contributed to technological innovations. The answer is option D.

PASSAGE 5
For policy makers to this day. GDP remains the definitive yardstick for economic performance, permitting them to assess the health and progress of a nation's economy and, by extension, people's lives. Yet GDP's dominance has brought criticism. It fails to capture changes to an economy's structure, such as the shifts to a service-led or technology-based economy. Some have protested that it fails to capture the unofficial or black market economy. Others have asserted that any purely economic indicator by itself may be inadequate to truly measure society's progress. It is therefore no surprise that over the last several decades, economists, • sociologists, and other academics have devised other metrics for tracking happiness, well-being, and social progress, some of which have garnered a substantial following. Implicit in these metrics is a challenge to GDP as the dominant measure of human progress-despite the fact that these measures sometimes themselves rely on GDP or some variance of GDP and come with limitations of their own. Even so, GDP remains a compelling measure of economic as well as social progress inasmuch as improvements in economic GDP translate into social progress. Policymakers have nevertheless become interested in these alternative measures, which, even if they do not displace GDP as the most prominent measure of economic growth, have value in complementing GDP in future assessments for economic and living standard progress. Furthermore, these proposed additions to GDP remind us that the endgame for public policy is progress and improved living standards rather than GDP growth for growth's sake. Nonetheless. these rankings reveal that consistently richer Countries (in terms of GDP) rank at the top of the indices and poorer ones at the bottom. For example, happiness indices reflect a demand that happiness be recognized as a criterion for government policy. First published in 2012, the World Happiness Report measures happiness by indexing GDP per capita alongside social support, life expectancy, freedom, generosity, and the absence of corruption. Of the 155 Countries collated in the 2017 World floppiness Report, the ten happiest countries, in descending order, are Norway. Denmark, Iceland, Switzerland. Finland, the Netherlands, Canada, New Zealand, Australia, and Sweden. The ten least happy countries, beginning with the least happy, are the Central African Republic, Burundi, Tanzania, Syria, Rwanda, Togo, Guinea, Liberia, South Sudan, and Yemen: While the United States is the largest country in GDP terms, it ranks fourteenth on the 2017 happiness index. A more traditional measure that goes beyond GDP alone is the United Nations' Human Development Index (HIM). First published in 1990, the HDI assesses longevity, education, and income across each nation's population, on the premise "that people and their capabilities should be the ultimate criteria for assessing the development of a country, not economic growth alone." The HDI reveals how two countries with the same level of gross national income (GNI)-that is, the total domestic output (GDP) plus foreign GDP generated by citizens abroad, minus domestic output created by foreigners-can end up with such different outcomes. In this way, it allows observers to compare the relative effectiveness of different policy choices and capital investments. In this index, Norway, Australia. and Switzerland rank at the top, with GNIs above USS40,000, and the Central African Republic, Niger, and Chad arc at the bottom of the index, all with GNIs of less than US$2,000 per capita. Some of these measures move beyond individuals and attempt a holistic assessment of the health of society. Since its founding in 2012, the Social Progress Imperative has offered a Social Progress Index that examines a range of social and environmental indicators beyond GDP, from access to electricity to religious tolerance; to measure three distinct dimensions of social progress: Basic Human Needs, Foundations of Wellbeing, and Opportunity. The 2017 Social Progress Index covers 133 countries and 94 percent of the world's population. The world as a whole would score 64.85 in Social Progress based on an average of all countries. On average, the top cluster of fourteen countries ranked as having "very high social progress"-including Denmark, Finland, Iceland, Norway, and Switzerland among others-scores 94.92 on Basic Human Needs, Foundations of Wellbeing, and Opportunity. The cluster of seven countries described as having' very low social progress" include the Central African Republic, Afghanistan. Chad, Angola, Niger, Guinea, and Yemen. For this cluster the average dimension scores of Basic Human Needs, Foundations of Wellbeing, and Opportunity are 42.67, 45.42, and 27.74. What can we learn from these various indices? While noneconomic factors such as health, well-being, and quality of life matter to humanity, economic measures such as GDP generally correlate to success in the other areas, with a small amount of variation among those who are awarded the top spot. In a nutshell, economic growth underpins all else; a country needs economic growth to achieve happiness, well-being, and ultimately human progress. To be sure, GDP estimates provide a snapshot of GDP at a single point in time, but nothing more. A large GDP can indicate that a country is rich yet mask that its economy might be struggling and scarcely growing.
What is the author's opinion regarding GDP as a measure for economic performance of a country?
In last paragraph it is mentioned that GDP estimates a snapshot of GDP(only economic perception) at a single point in time, but nothing more. A large GDP can indicate that a country is rich yet mask that its economy might be struggling and scarcely growing. This implies that GDP provides accurate and incomplete information.
The answer is option C.
What are the characteristics of non GDP measures?
As per the passage, Non GDP measures such HDI, SPI goes beyond the economic factors, i.e. social progress, education, well being, quality of life etc., Option C captures the point correctly. The answer is option C.
According to the passage, what is the difference between using just GDP measures and using non GDP measures in policy making?
The passage highlights that GDP is a valuable economic indicator that measures economic performance, but it doesn't capture other important factors like happiness, well-being, and social progress. Non-GDP measures, such as the World Happiness Report, HDI, and Social Progress Index, provide a broader picture that can reveal gaps in public policy, focusing on social and environmental aspects beyond just economic performance. This is captured in Option C.
Option A: The passage does not claim that GDP correlate to overall success or that non-GDP measures do not contribute to understanding social progress.
Option B: The passage mentions non-GDP indices as being important and valuable, and while they may not be perfect, they aren't open to interpretation. They aim to assess different dimensions of social progress, which can also inform policy decisions.
Option D: The passage does not mention that most countries do not accept non-GDP measures.

Options A and D have errors in parallelism. Option B mentions 'from...and to' which is not correct. Option C is correct, considering all the aspects. The answer is option C.
Although the square root of a negative number has no real value, it is not necessarily true that equations involving imaginary numbers like these are practically inapplicable.
The idea conveyed by the whole sentence is that while the square root of a negative number has no real value, equations involving such numbers may have practical applications. Due to the usage of "not necessarily," the answer we are looking for should be phrased as "such equations have no practical applications" and the double negation will give the sentence a positive essence.
The only answer that conveys the required sense is B.
The sentences given in each question, when properly sequenced, form a coherent paragraph. Each sentence is labelled with a letter. Choose the most logical order of sentences from among the given choices to construct a coherent paragraph.
A. But, clearly, the government still has the final say.
B. In the past few years, the Reserve Bank of India might have wrested considerable powers from the government when it comes to monetary policy.
C. The RBI's announcements on certain issues become effective only ,after the government notifies them.
D. Isn't it time the government vested the RBI with powers to sanction such changes, leaving their ratification later?
B is an opening statement in which it is suggested that that RBI has taken over several aspects of monetary policies from the government. A indicates that despite having certain powers, the final decision rests with the government. C elaborates A with an example. D poses a question for the reader to decide after reading all the above statements.
Hence the correct order is BACD.
A. All levels of demand, whether individual, aggregate, local, national, or international are subject to change.
B. At the same time, science and technology add new dimensions to products, their uses and the methods used to market them.
C. Aggregate demand fluctuates with changes in the level of business activity, GNP and national income.
D. The demand of individuals tend to vary with changing needs and rising income.
Sentence A gives the basic premise of what is being discussed in the passage i.e. that all demands are subject to change. Thus, sentence A is apt as the opening sentence of the paragraph. D further discusses the individual demands and C discusses aggregate demand. DC discuss the demands chronologically and hence ADC is the mandatory pair. B is driving the paragraph on a tangential nuanced idea apart from demand. Thus ADCB is the right choice.
A Business Group has 3 Companies X,Y,Z and a Trust P which is engaged in charitable activities. Each group company has to donate 5% of its own funds to the Trust, excluding the loan which the company has taken from other companies of the group. X has given a loan to Y which is equivalent to 10% of the funds of Y. After receiving the loan, Y has funds which are 2 times the funds of Z. If Z gave Rs. 10,000 as donation to the Trust P, how much is the approximate contribution of 'Y' to the Trust P ?
Z's funds = 10000 x 100/5 = 2 lakhs
Y has funds which are 2 times the funds of Z => 4 lakhs
X has given loan to Y which is equal to 10% of funds of Y
y's funds + 10% of Y's funds = 4 lakhs
Y's funds = 4/1.1 lakhs
Y's donation = 5/100 (4/1.1lakhs) = 18181.81
A bucket contains 200cc of liquid. A solid ball is dropped in the bucket resulting in the rise of liquid level to 1.3 times of its original level. If the radius of the base of the bucket is 3 cm and the radius of the surface of the liquid level is 1 cm more than the radius of the base of the bucket before the ball is dropped. Find the volume of the solid metal ball.
Let height of liquid level before the ball was dropped be h
The radius of the surface of the liquid level then is 4cm
We know that the volume of the bucket or frustum is V = $$\frac{1}{3}\pi h(R^2+r^2+Rr)$$
$$\frac{h}{3}\pi\ \left(4^2+3^2+4\cdot3\right)\ =200cc$$
=> h = $$\frac{600}{37\pi\ }$$
The liquid level raises by 0.3h as a result of the solid metal ball being dropped.
By similarity, the radius of the surface of the liquid level after metal ball is dropped is 4.3cm
Volume of he solid metal ball = $$\frac{1.3h}{3}\left(4^2+3^2+4.3\left(3\right)\right)\ -\ 200$$ = 83.82cc

Using 5 dots in each of the lines PQ, RS, TU and VW as the vertices, how many triangles can be drawn such that the base is on any one of the above lines?
The base on any one of the lines can be formed in $$5_{C_2}=10\ ways$$
To form a triangle, the base has to be joined to any of the 15 points on the other lines
Number of triangles that can be drawn when the base is on any of the lines = 10 *15 =150
and number of triangles that can be drawn totally = 150*4 = 600
In the triangle PQR, S is the midpoint of QR. X is any point on PR. T is the point on QR such that PT || SX. If the area of triangle PQR is 5.8 sq. cm. then the area of triangle RTX is
S is the midpoint of QR. So, area of PSR = $$\frac{1}{2}\left(Area\ of\ PQR\right)\ =\ \frac{5.8}{2}=2.9$$
PT||XS
So area of XSP = area of XST ( same height and same base)
Adding area of XSR on both sides, we have area of PSR = Area of RTX
=> area of PSR = Area of RTX = 2.9 sq.cm
Given $$P(x,y) = x^2+ xy + y^2; Q(x,y) = x^2- xy + y^2.$$ Find the value of $$P(7, Q(9,4))$$
Q(x,y) = x^2- xy + y^2.$$
Q(9,4) = $$9^2-4\cdot9+4^2=81+16-36=61$$
P(7,61) = $$7^2+7\cdot61+61^2=\ 49+427+3721=4197$$
In the given figure, PA=QB and PRQ is the arc of the circle, centre of which is O such that angle POQ = 90°. If AB= 25$$\sqrt{2}$$cm and the perpendicular distance of AB from centre O is 30cm. Find the area of the shaded region?

PA = QB and A=B = $$90^{\circ\ }$$
=> PQBA is a rectangle.
Area of the shaded region = (Area of PQBA - Area of the segment PRQ)
$$PQ=AB=25\sqrt{\ 5}$$
$$PO=QO=\frac{PQ}{\sqrt{\ 2}}=25$$ = radius of the circle.
The perpendicular from O to PQ is $$\frac{25}{\sqrt{\ 2}}$$
Distance from the foot of the perpendicular to AB = $$30-\frac{25}{\sqrt{\ 2}}$$
Area of PQBA = $$\left(30-\frac{25}{\sqrt{\ 2}}\right)\left(25\sqrt{\ 2}\right)=750\sqrt{\ 2}-625$$
Area of segment PRQ = Area of sector OPRQ - Area of triangle OPQ = $$\frac{90}{360}\pi\ 25^2-\frac{1}{2}25^2$$
Area of shaded region = $$\left(750\sqrt{\ 2}-625\right)-\left(\frac{90}{360}\pi\ 25^2-\frac{1}{2}25^2\right)$$

The roots of quadratic equation $$y^2 -8y + 14$$ are $$\alpha$$ and $$\beta$$. Find the value of $$(1 + \alpha + \beta^2)(1 + \beta + \alpha^2)$$
$$\alpha\beta\ \ =\ 14$$
$$\alpha\ +\beta\ \ =\ 8$$
$$(1 + \alpha + \beta^2)(1 + \beta + \alpha^2)$$ = $$1+\beta\ +\alpha\ ^2+\alpha\ +\alpha\ \beta\ +\alpha\ ^3+\beta\ ^2+\beta\ ^3+\left(\alpha\ \beta\ \right)^2$$
$$\alpha\ ^2+\beta\ ^2=\left(\alpha\ +\beta\ \right)^2-2\alpha\ \beta\ \ =\ 64-28\ =\ 36$$
$$\alpha\ ^3+\beta\ ^3=\left(\alpha+\beta\ \ \right)^3-3\alpha\ \beta\ \left(\alpha\ +\beta\ \right)=512-336=176$$
Hence $$1+\beta\ +\alpha\ ^2+\alpha\ +\alpha\ \beta\ +\alpha\ ^3+\beta\ ^2+\beta\ ^3+\left(\alpha\ \beta\ \right)^2$$ = 1 + 8 + 36+176+14 + 196 = 431

Ram, Ravi and Ratan can alone finish an assignment in 9 days, 12 days and 15 days respectively. They decide to complete a work by working in turns. Ram works alone on Monday, Ravi does the work alone on Tuesday, followed by Ratan working alone on Wednesday & so on. What proportion of the complete work is done by Ravi?
Part of the work completed on Monday, Tuesday and Wednesday = 1/9 +1/12 + 1/15 = 47/180
Part of the work completed at the end of 9 days of work = 47(3)/180 = 47/60
remaining part of the work= 13/60 = 39/180
Part of the work completed by ram on 10th day = 1/9 = 20 /180
Part of the work completed by Rvi on 11th day = 1/12 = 15/180
remaining part of the work = 4/180
Ratan can do 12//180th of work on 12th day. Hence he needs 1/3rd of the 12th day.
Proportion of the completed work done by Ravi = 3(1/12) + 15/180 = 1/3

Joseph diametrically crosses a semi-circular playground and takes 48 seconds less than if he crosses the playground along the semi-circular path. If he walks 50 metres in one minute, the diameter of playground is
Speed of joseph = 50/60 = $$\frac{5}{6}$$ m/s
Let the radius of circular playground be r
Speed = distance/ time
Time to diametrically cross a semi-circular playground t1= $$\frac{2r}{\frac{5}{6}}$$ = $$\frac{12r}{5}$$
Time to cross the playground along the semi-circular path t2 = $$\frac{\pi\ r}{\frac{5}{6}}=\frac{\left(6\pi\ r\right)}{5}$$
t1-t2 = 48
$$\frac{12r}{5}-\frac{\left(6\pi\ r\right)}{5}\ =\ 48$$
=> r = 35m
hence diameter = 70m
Garima had only Rs. 200. Rs. 500 and Rs. 2000 notes in her wallet. She goes to Shoppers Stop. purchases some dresses and gives half of her Rs. 2000 notes & in turn receives same number of Rs. 200 notes. She then goes to a restaurant and gives all her Rs. 500 notes and receives thirty Rs. 2000 notes, which increases the number of Rs. 2000 notes she had by. 75%.- If now she has fifty Rs. 200 notes. what were the original number of Rs. 2000 and Rs. 200 notes she had at the start?
Garima had x notes of Rs 2000. She gave x/2 notes of Rs 2000. She is left with x-x/2 = x/2 notes
x/2 + 30 = 1.75x/2
=> x= 80
So, she remains 80/2 = 40 Rs 200 notes
So she must be having 50-40 = 10 Rs 200 notes.
A metallic solid is made up of a solid cylindrical base with a solid cone on its top. The radius of the base of the cone is 5 cm. and the ratio of the height of the cylinder and the cone is 3:2. A cylindrical hole is drilled through the solid with height equal to 2/$$3^{rd}$$ of the height of solid. What should be the radius (in cm) of the hole so that the volume of the hole is 1/$$3^{rd}$$ of the volume of the metallic solid after drilling?
H - volume of hole
R - volume of remaining solid
T - Total volume
It is given, $$H\ =\ \frac{1}{3}R$$
H + R = T
T = 4H
$$\frac{1}{3}\pi\ \left(25\right)\left(2x\right)+\pi\left(25\right)\left(3x\right)=4\times\pi\ r^2\left(\frac{10}{3}x\right)$$
$$r^2=\frac{275}{40}$$
$$r\ =\sqrt{\frac{\ 55}{8}}$$
The answer is option D.
Nitin installed an overhead tank on the roof of his newly constructed house. Three taps are connected to the tank: 2 taps A and B to fill the tank and one tap C to empty it. Tap A alone can fill the tank in 12 hours, while tap B alone takes one and a half times more time than tap A to fill the tank completely. Tap C alone can empty a completely filled tank in 36 hours. Yesterday, to fill the tank, Nitin first opened tap A, and then after 2 hours opened tap B also. However after 6 hours he realised that tap C was open from the very beginning. He quickly closes tap C. What will be the total time required to fill the tank?
Tap A alone can fill the tank in 12 hours
Tap B alone can fill the tank in 12*1.5 = 18 hours
Tap C alone can empty the tank in 36 hours
Let the total volume of the tank be 36 units
A fills 3 units, B fills 2 units and C empties 1 units in an hour.
Let the total time taken be 't'
t(3) + (t-2)2 - 6(1) = 36
5t = 46
t = 9.2 hrs = 9 hours 12 minutes
The answer is option C.
At the foot of the mountain, the angle of elevation of the summit at the top of the mountain is 45°. After ascending 100 metres, at a slope of 30° up the mountain towards the summit. the angle of elevation of the summit is 60°. Find the height of the summit.

Let the point intersecting inside triangle ABC be 'E'.
It is given, $$\ \angle\ AED$$ = 60, $$\ \angle\ ABC$$ = 45, $$\ \angle\ EBC$$ = 30 and BE = 100
At point E, $$\ \angle\ BEF\ =60,\ \angle\ DEF=90\ and\ \angle\ AED\ =\ 60$$
$$\ \angle\ AEB\ =\ 360\ -\ 60\ -\ 60\ -\ 90\ =\ 150$$
In triangle AEB, $$\ \angle\ EAB\ =\ 180\ -\ 150\ -\ 15\ =\ 15$$
$$\ \angle\ EAB\ =\angle\ EBA$$
Therefore, EA = 100 (as BE = 100)
EF = DC = 50
In triangle AED,
$$ED^2+AD^2=AE^2$$
ED = x, AD = $$\sqrt{\ 3}$$x
$$4x^2=\left(100\right)^2$$
2x = 100
x = 50
Height of summit = $$\sqrt{\ 3}x\ +\ 50$$ = $$50\left(\sqrt{\ 3}+1\right)$$
The answer is option A.
Land Cruiser Prado, the latest SUV from Toyota Motors, consumes diesel at the rate of $$\frac{1}{400}\left\{ \frac{1000}{x} + x\right\}$$litres per Km. when travelling at the speed of x km/hr. The diesel costs Rs. 65 per litre and the driver is paid Rs. 50 per hour. Find the steady speed that will minimize the total cost of a 1000 km trip?
Total cost=Fuel cost+ Driver’s cost
Fuel cost=Total distance × Cost of Diesel per km
Fuel cost=1000×[1/400 {(1000/x)+x} ]×65
Fuel cost = 162500/x + 162.5x
Now, substituting the values from the given choices, we find that at x=36, the total cost is minimum.
Hence. Option B is correct.
In a survey on the viewership of the TV channels, 73% of those surveyed viewed at least one of the three Channels: Star Plus, Sab TV, and Sony. 38% of those surveyed viewed Star Plus, 39% viewed Sony, and 23% viewed Sab TV. 11% of all those surveyed viewed all the three channels. What percentage of those surveyed, viewed more than one of the three TV channels?

It is given that 73% of those surveyed viewed at least one of the three Channels; this implies 27% viewed none of the channels
a + b + c + d + e + f + g = 73
It is given, g = 11
a + b + c + d + e + f = 62 ......... (1)
a + b + c + 2(d+e+f) + 3g = 38 + 39 + 23
a + b + c + 2(d+e+f) + 3g = 100
a + b + c + 2(d + e + f) = 67 .......... (2)
Subtracting (1) from (2), we get
d + e + f = 67 - 62 = 5
The percentage of those surveyed, viewed more than one of the three TV channels = d + e + f + g = 5 + 11 = 16
The answer is option A.
A physical therapist of Russian football team knows that the team will play 40% of its matches on artificial turf, this season. Because of his vast experience, he•knows that a football player's chances of incurring a knee injury is 50% higher if he is playing on artificial turf instead of grass. If the player's chances of a knee injury on artificial turf is 0.42, what is the probability that a football player with knee injury, incurred the injury while playing on grass?
Probability of playing on grass = 0.6
Probability of playing on Artificial turf = 0.4
Probability of injury on artificial turf = $$\frac{3}{2}$$(probability of injury on grass)
0.42 = $$\frac{3}{2}$$(probability of injury on grass)
Probability of injury on grass = 0.28
Applying Baye's theorem,
Probability of injury on grass = $$\ \frac{\ 0.6\times\ 0.28}{0.6\times\ 0.28+0.4\times\ 0.42}\approx\ 0.5$$
The answer is option C.
The square root of $$1 + x^2 + \sqrt{1 + x^2 + x^4}$$is
$$1+x^2+\sqrt{\ 1+x^2+x^4}$$
=$$\frac{1}{2}\left(2+2x^2+2\sqrt{\ 1+x^2+x^4}\right)$$
=$$\frac{1}{2}\left(1+x+x^2+1-x+x^2+2\sqrt{\left(1+x+x^2\right)\left(1-x+x^2\right)}\right)$$
=$$\frac{1}{2}\left(\sqrt{\ 1+x+x^2}+\sqrt{\ 1-x+x^2}\right)^2$$
$$\sqrt{\ 1+x^2+\sqrt{\ 1+x^2+x^4}}=\sqrt{\frac{1}{2}\left(\sqrt{\ 1+x+x^2}+\sqrt{\ 1-x+x^2}\right)^2\ }$$
$$\sqrt{\ 1+x^2+\sqrt{\ 1+x^2+x^4}}=\frac{1}{\sqrt{\ 2}}\left(\sqrt{1+x+x^2}+\sqrt{\ 1-x+x^2}\ \right)$$
The answer is option A.
$$\log_2 x.\log_{\frac{x}{64}}2 = \log_{\frac{x}{16}}2$$; then $$x = ?$$
$$\log_ba\ =\ \frac{1}{\log_ab}$$
$$\log_2 x.\log_{\frac{x}{64}}2$$ = $$\frac{\log_2x}{\log_2\left(\frac{x}{64}\right)}=\frac{\log_2x}{\log_2x-6}$$
Similarly,
$$\log_{\frac{x}{16}}2$$=$$\frac{1}{\log_2x-4}$$
Let $$\log_2x=t$$ => $$\frac{t}{t-6}=\frac{1}{t-4}$$ => $$t^2-5t+6=0$$ => $$\left(t-2\right)\left(t-3\right)=0$$ => t=2,3
.'. $$\log_2x=2\ or\ 3\ =>\ x=4\ or\ 8.$$
Hence, B is correct.
