Given: Anuj takes 1 day to complete a job. Bharat takes twice the time as Anuj to complete the same job. Chetan takes twice the time as Bharat to complete that job. Dhiraj takes twice the time as Chetan to complete that job.
(A) Chetan and Dhiraj will take 8/3 days to complete the work
(B) The second fastest pair to complete the work is Anuj and Dhiraj
(C) The second slowest pair to complete the work is Bharat and Dhiraj
(D) Bharat and Dhiraj will take 4/3 days to complete the work
Anuj takes 1 day to complete
Bharat takes 2 days
Chetan takes 4 days and Dhiraj takes 8 days to complete
option A chetan and Dhiraj together will take $$\frac{4\times\ 8}{4+8}=\frac{32}{12}=\frac{8}{3\ }days$$so A is correct.
Now calculating for all we get AB in 2/3 days AC in 4/5 days AD in 8/9 days BC in 8/6 days BD in 16/10 days
So we can say BD is 2nd slowest pair
Hence A and C are correct
How many ten-digit numbers can be formed using all the digits of 2435753228 such that odd digits appear only in even places?
we have : 2435753228
Now here we have 5 odd digits and 5 even digits and total 10 places
so 5,5,3,3,7 will arrange in 5 places and 2,2,2,8,4 will arrange in 5 places
we get : total arrangements =$$\frac{5!}{3!}\times\ \frac{5!}{2!\times\ 2!}$$
we get $$\frac{\left(5!\right)^2}{3!\ \left(2!\right)^2}$$
Given below are two statements
Statement I : $$(543)_6$$ is equivalent to $$(317)_8$$
Statement II : The last 4 bits in the binary representation of a multiple of 16 is 1000.
In light of the above statements, choose the correct answer from the options given below
543 in base 6 expressed in decimal form =5(36)+4(6)+3 =207
317 in base 8 expressed in decimal form = 3(64)+8+7 =207
So statement 1 is correct
Now 16 in base 2 = 10000
32 in base 2 = 100000
Therefore statement 2 is false
Hence C is the correct answer
During the next year, the probability that a Company A releases a mobile is 0.7. The probability that mobile is a success. given that it is released by the Company is 0.8. The probability that a mobile is a success and released by a Company B is 0.28. A mobile released by either Company A or Company B during the next one year is a success. Find the probability that it is released by Company A.
Probability that A releases a mobile = 0.7
Probability that mobile is a success given that it is released by A = 0.8
Probability that mobile is released by A and is success = 0.8*0.7 = 0.56
And probability that mobile is a success and released by B = 0.28
Total probability for success = 0.56+0.28 = 0.84
Now Probability that it is success and is released by A = 0.56/0.84 = 2/3
If a is $$\frac{3}{2}$$ times of b, b is $$\frac{3}{4}$$th of c and d is $$\frac{1}{4}$$th of c, the ratio of a and d is
$$a=\frac{3}{2}b$$
b=$$\frac{3}{4}c$$ and
d=$$\frac{c}{4}$$
c=4d
Now substituting we get
$$a=\frac{3}{2}\ \times\ \frac{3}{4}\times\ 4d$$
so we get a=$$a=\frac{9}{2}d$$
a:d=9:2
Pipe X can fill a tank in 12 hours and pipe Y can empty the tank in 18 hours. Both pipes are opened at 8 am and after some time Y is closed, and the tank is full at 10 pm on the same day. At what time was pipe Y closed?
Let volume be 36 units
so X fills at 3 units per hour and Y empties at 2 units per hour
Now Tank was filled in 14 hrs so X filled 14*3 =42 units
Now therefore Y emptied 6 units
so it will empty 6 units in 3 hours
so Y will be closed at 11 am
The price of an apple is twice that of an orange. The price of an orange is thrice that of a banana.If the price of an apple increases by 10%, price of an orange increases by 30% and the price of a banana increases by 20%. Find the percentage increase in the price of 20 apples, 20 oranges and 20 bananas.
Let price of banana be x
so price of orange = 3x
and price of apple will be 6x
Price of 20 bananas , apples and oranges = 200 x (1)
Now f the price of an apple increases by 10%,
it becomes = 6.6x
so price of 20 apples = 132x
if price of an orange increases by 30% it becomes = 3.9x
so price of 20 oranges = 78x
if price of a banana increases by 20%
it becomes 1.2 x
so price of 20 bananas = 24x
Now total price of 20 bananas , apples and oranges =234x (2)
So Percentage change in price = $$\frac{234x-200x}{200x}\times\ 100=\ 17$$%
The difference between the compound interest and simple interest for two years on a certain sum at a certain rate of interest is Rs. 64. The compound interest for two years is Rs. 704. The principal is
We have
$$P\left(\frac{R}{100}\right)^2=\ 64$$
And
$$P\left(1+\left(\frac{R}{100}\right)\right)^{^2}-p\ =\ 704$$
Now dividing both we get :
$$\frac{\left(\frac{R}{100}\right)^2}{\left(1+\frac{R}{100}\right)^2-1}\ =\ \frac{1}{11}$$
Solving we get R/100 = 5
Now substituting we get P = 64*25 = 1600
A vessel has 500 litres of milk. 50 litres of milk is replaced with 50 litres of water in this vessel. If this operation is repeated another 2 more times, whatis the percentage of milk in the vessel at the end?
We have formula :
F = $$I\left(1-\frac{K}{\left(V\right)}\right)^n$$
Here n =3 V =500 k =50
substituting we get
F/I = 729/1000
Therefore in percentage F = 72.9 percent

A started a business with Rs. 50000. After three months, B joins with an investment of Rs. 60000 and A withdraws Rs. 10000 out of his capital. Three months later, B brought in Rs. 20000 more. At the end of the year, what should be the ratio in which they A and B share the profits?
Profit share = Investment * Time period
Now we get ratio of profit of A and B :
$$\frac{50,000\times\ 3\ +\ 40,000\times\ 9}{60,000\times\ 3\ +\ 80,000\times\ 6}$$
we get ratio as $$\frac{510}{660\ }=\ \frac{17}{22}$$
In a company there are 252 engineers, in which the ratio of the number of electronics engineers and computer engineers is 2 : 1. The ratio of the number of electronics engineers and computer engineers becomes 1:1 after recruitment of some more computer engineers. The average age of all the engineers is now 22 years and the average age of the computer engineers is 2 years less than the average age of electronics engineers.
(A) The average age (in years) of electronics engineers is 21
(B) The average age (in years) of computer engineers is 21
(C) The average age (in years) of electronics engineers is 23
(D) The average age (in years) of electronics engineers is 25
(E) The average age (in years) of computer engineers is 23
Choose the correct answer from the options given below:
Number of electronics engineers initially = $$\frac{2}{3}\times\ 252\ =\ 168$$
So number of computer engineers initially = 252-168 =84
Now number of computer engineers recruited to make ratio 1:1 = 168-84 =84
Let average age of computer engineers be x
so total age will be 168x
Now average age of electronics engineers will be : x+2
So total age will be : (x+2) 168
Now as per given
Total age = 336(22)
Equating we get :
336(22) = 336(x+1)
we get x=21
so B and C are correct
In triangle PQR. PS is perpendicular to QR and S divides QR in the ratio of 3 : 1 internally. If PQ=21 and PR =9,find QR.
we have :
Triangles PSR and PSQ are right triangles
so using pythaghoras theorem
we get
441 = $$PS^2+9x^2$$
81 =$$PS^2+x^2$$
subtracting we get
360=$$8x^2$$
$$x^2\ =45$$
x=$$3\sqrt{\ 5}$$
QR = 4x = $$12\sqrt{\ 5}$$

In a 1000 metre race, Rahul reaches the finishing line 5 seconds before than Raj and beats Raj by 50 metre. What is Rahul's speed (in m/s)?
Let speed of Raj be v1 and speed of Rahul be v2
Now Rahul reaches 5 seconds before Raj and beats him by 50m
so Raj covers 50m in 5 seconds
so v1 = 10m/s
Now When Raj covers 950m Rahul covers 1000m (in the same time )
so we get $$\frac{v1}{v2}=\frac{1000}{950}$$
v1 =$$\frac{200}{19}\ =10\ \frac{10}{19}\ $$ m/sec
A shopkeeper claims to sell rice at cost price. He uses a false weight with the intention of selling rice at 25% profit. After selling Rice to a customer, he realizes that the customer has paid 10% less than what he should have paid. What is the actual profit percentage made by the shopkeeper?
Let cost price be 1000 per Kg of rice
Now to make 25% profit at 1000
He will sell 800 gm of rice
Now C.P of 800 gm of rice = 800
Now he sold at 10% less than 1000 so S.P = 900
Now therefore profit = $$\frac{900-800}{800}\times\ 100\ =\ \frac{100}{8}=12.5\ \%$$
Meera and Sarika attempted to solve a quadratic equation in x. Sarika made a mistake in reading the coefficient of x and obtained the roots as 12 and 16. Meera made a mistake in reading the constant term of the equation. She obtained the roots as-22 and - 6. The corrects root(s) is (are) :
(A) -16
(B) -12
(C) 12
(D) 16
Choose the correct answer from the options given below:
Let quadratic equation be $$x^2+bx+c\ =0$$
Now Sarika made a mistake in reading b , so she would have read c correctly
so c/1 = product of roots =192 (1)
Meera made a mistake in reading the constant term of the equation so she would have read b correctly
now sum of roots = -b/1 =-28 (2)
we get b =28 , c =192
so quadratic becomes
$$x^2+28x+192$$
we get (x+16)(x+12) =0
roots are -16 , -12

Which of the following equations best describes the graph given below?
In these type of questions
we go through the options :
Now when x=6 or -6 the value of y is 0
so let us put value of y=0 in all options and check which option satisfies x=6 and -6
Putting x=6 and y=0 in option A
we get |6+0|-|6-0| = 0
But RHS =6 so this option is discarded
Now putting in option B
|6-0|+|6+0| =12
But RHS is 10
so this option is also discarded .
Now option C we get
|6|-0 =6
so we can say graph can be of |x|-|y|=6
Now satisfying option D
we get |6+0|-|6-0|=0
So we can say 6,0 and -6,0 satisfies option D as well
Now you have to eliminate between C and D
If you observe |x+y|-|x-y|=0 will pass through origin
and the graph here is not passing through origin so you can eliminate option D
Therefore the graph will be |x|-|y|=6
In a company, the average salary of the boys is Rs. 50000. The average salary of all the employees is Rs. 48000. There are 80 boys in the company and the average salary of the girl is Rs. 40000. What is the number of girls working in the company?
Let girls be x
Total employees will be 80+x
now total value of money will be same :
i.e Average of 1employee (Number of employees ) will be equal to (Average of boys)* Number of boys +(Average of girls)*Number of girls
we get 48000(80+x) = 50,000(80)+40,000(x)
48(80+x) = 50(80) +40x
we get 8x =160
x=20
A roller is 4m long and has a diameter of 0.7m. It takes exactly 2000 rotations of the roller to level a road. If the cost of using the roller is Rs.4 per square metres, then the total cost of levelling the roadis :
Assume, $$\pi=\frac{22}{7}$$
Curved Surface area of roller = $$2\pi\ rh$$
Cost = Area covered* cost per meter square
so we get total cost = $$2\times\ \frac{22}{7}\times\ \frac{7}{20}\times\ 4\times\ 4\times\ 2000$$
=Rs 70,400

Study the pie chart and answer the questions that follow:
Note : The value of exports represents the angle corresponding to each country in the pie chart.
The ratio of the value of exports between the total exports of USA and Japan to the total exports of Australia and France is
Total value for USA and Japan = 54+45 = 99
Total value for Australia and Japan = 18+27 = 45
The ratio of the total exports of the USA and Japan to the total exports of Australia and France = 99:45 = 11:5
What is number of countries whose exports are more than the average exports per country? (Assume‘Others’ as a single country)
Total countries = 10
So average angle will be 360/10 = 36
Now therefore countries subtending angle>35 are 5 .
By how much does the value of the exports of Japan exceed that of Australia?
Angle exceeds by 45-18 =27
so value will be $$\frac{27}{360}\times\ 144,000$$= 10,800 billion$
What is value of total exports of USA and France as a percentage of the total exports of Japan, China, Russia and Hongkong?
Total angle of USA and France =81
Total angle of Japan, China, Russia and Hongkong =122.4
Now therefore total exports of USA and France as a percentage of the total exports of Japan, China, Russia and Hongkong:$$\frac{81}{122.4}\times\ 100=66.1764$$
The minimum value of $$\frac{3(6+x)(x+12)}{2(4+x)}$$, Where $$x>-4$$ is
Let $$x+4=y$$
So, the expression $$\frac{3\ \left(x+6\right)\left(x+12\right)}{2\left(x+4\right)}$$ equals $$\frac{3*(y+2)(y+8)}{2*y}$$
This equals $$\frac{3}{2} \times (y+16/y+10)$$
The minimum value of $$y+16/y$$ is 8 when $$y$$ equals 4
So, the minimum value of the expression is 3/2*18 = 27
Let $$g(x)+g(\frac{1}{x})=1+3x$$. Find the value of $$g(3)$$.
The question appeared in CMAT 2021 Slot 2 and the question is incorrect . Marks were awarded to students.
Find the sum ofthe following series (with infinite terms):
$$2\sqrt{2},\frac{4}{\sqrt{3}},\frac{4\sqrt{2}}{3},.....$$
The series is an infinite Geometric progression with first term as $$2\sqrt{\ 2}$$ and common ratio $$\sqrt{\ \frac{2}{3}}$$
Now we know that sum of an infinite geometric progression = $$\frac{a}{1-r}$$ where r is the common ratio and a is first term
so we get sum =$$\frac{2\sqrt{\ 2}}{1-\sqrt{\ \frac{2}{3}}}$$
=$$=\ \frac{2\sqrt{\ 6}}{\sqrt{\ 3}-\sqrt{\ 2}}$$
Rationalizing the denominator
we get :$$=\frac{2\sqrt{\ 6}\left(\sqrt{\ 3}+\sqrt{\ 2}\right)}{3-2}$$
= $$2\sqrt{\ 6}\left(\sqrt{\ 3}+\sqrt{\ 2}\right)$$
In a certain language
ABCD is coded as CABF

If A # B means A is the mother of B
A $ B means A is the father of B
A % B means A is sister of B
A * B means A is the son of B
A @ B means A is brother of B and
A ! B means A is the daughter of B
In the expression P$Q#R@S, how is R related to P?
P$Q means P is the father of Q
Now Q#R will mean Q is mother of R
So we can say R's mother's father is P
So R is either Grand daughter or Grand son of P
Now R@S means R is brother of S so R is a male so R is grandson of P

210-195 =15 ; 195-175 =20 ; 175-150 =25 ; 150-120 =30
so we get next number as 120-35 =85
P,Q, R, S, T, U, V, W are sitting in a row facing north
(A) P is fourth to right of T
(B) S is fourth to the left of Q
(C) R and U, which are both at the ends are neighbours of Q and T respectively
(D) W is immediate left of P and P is neighbour of Q
Who are the immediate neighbours of W?
From A and C we get
UT_ _ _ _PQR
Now combining all we get :
UTSVWPQR
So neighbours of W are P and V
P,Q, R, S, T, U, V and W are sitting round the circle and are facing the centre: P is second to the right of T who is the neighbour of R and V. S is not the neighbour of P. V is the neighbour of U. Q is not between S and W. W is not between U and S. U is the rightof S.
Who is sitting adjacent to V?
We get the arrangement as :
U and T are adjacent to V
Three out of four are alike in a particular pattern and hence form a group. Find which does not belong to the group
2835, 5671, 8505, 11344
Now 5671-2835 =2836
8505-5671 =2834
Now 11344-8505=2839
Now the difference should have been 2832 so we can say 11344 is the wrong term or it do not belong the group

What is the input if the following is the arrangement of Step IV?
9, 75, 113, 213, 33, 5
Step IV we have 9, 75, 113, 213, 33, 5
Now step II+5 = Step III and Step III-2 =StepIV
So we get Step II Step IV -3
Now so Step II =6,72,110,210,30,2
Now Input is k then step 1 is k^2 and step 2 is k^2+k
so equating k^2+k with numbers we get input as :
2,8,10,14,5,1
Among the six persons P, Q, R. S, T, U. each is having different weights
P is heavier than 3 persons. R is lighter than T
S is lighter than only Q
R is not the lightest
Who is lighter and heavier than P respectively?
S is lighter than only Q so we can say S is 2nd heaviest and Q is heaviest
P is heavier than 3 persons so P is the third heaviest
we get Q>S>P
Now T>R as per 1 and R is not the lightest so U is the lightest
we get Q>S>P>T>R>U
so T and S are lighter and heavier than P respectively.

Read the Passage below and answer the question that follows:
Human beings are connected at the level of feeling and emotion: in such a degree that there is practically a subterranean network of the psyche in which some encounters are damaging, some nourishing. This emotional exchange is typically at a subtle. almost imperceptible level. The way a colleague says ‘thank you’ can leave one feeling ignored, resented or genuinely welcomed and appreciated. We catch feelings from one another as though they were some kind of social virus. Every space is full of emotional signals and every time people connect, they transmit and receive those signals. These emotional encounters have an effect on all the people in that particular circle. Those who are socially skillful can control these emotional messages. A civil and polite society is able to regulate and control these emotional relationships in less damaging ways. The Emotional Quotient of a society is the sum total of the emotional intelligence of its citizens. When we compliment others for being considerate, we are actually acknowledging their emotional intelligence. The company of such people is a relaxing experience and they are a valuable and enriching presence in any society. Whether we like it or not, we are all interdependent in terms of our feelings and emotions and our emotional intelligence form the framework of society.
The author feels that when we meet people some meetings can be
According to the given passage, the company of some people is a relaxing experience, they are a valuable and enriching presence in any society. Therefore, answer is option B.
The company of what kind of people is relaxing?

Read the passage and answerthe question thatfollows:
The human body is nothing but a set of chemical reactions in some form or the other. The religious scriptures believe that man was made out of the image of the creator of the universe. Does this mean that Oxygen was pumped into the human body and carbon dioxide pumped out to create this being? Is life just the process of oxygenation and decarburization? If the human body is managed by these two processes, then we can safely believe that life came into existence due to these chemical reactions. The highly complex chemicals compounds present in the human body are not evident in lower animals or plants. These substances were born because of the synthesis of other smaller molecules.
A large number of recognized chemicals has been observed and provedto be involved in the transmission of impulses from one tissue or cell to another. Some examples of such chemicals are adrenaline, dopamine, acetylcholine, endorphins and encephalin. The increase or decrease of any one of these chemicals, interferes with the normal functioning of cells and tissues. This creates diseases in the body, and the restoration of their supply cures the diseases. The deficiency of acetylcholine leads to Alzheimer’s disease, while a decrease in dopamine leads to Parkinson’s disease and its increase causes schizophrenia, a mental disorder. Endorphins and encephalon work like a drug to produce sensations like pleasure and reduce pain. In depressed persons, lower levels of serotonin and adrenaline are observed. Exercise and meditation help release endorphins in order to produce a scene of calmness and pleasure. As for love, the brain releases a chemical substance called phenyl ethylene which acts like an amphetamineto increase mental alertness and physical energy. People with low levels of these chemicals develop a craving for foods such as chocolates, which are rich in such compounds.
Which one of the words given below can be used in place of ‘a mental disorder’ as used in the passage?
In the second paragraph of the passage, the author mentions, "while a decrease in dopamine leads to Parkinson’s disease and its increase causes schizophrenia, a mental disorder."
Hence, the answer is option D.
Which one of these wordsis the right synonym for ‘synthesis’ as used in the passage:
Consider the last line of the first paragraph: "These substances were born because of the synthesis of other smaller molecules."
From this context, we can infer that 'synthesis' means "mixing/combining". Among the option, Fusion and Union are the candidates. Fusion is a better alternative than Union in this context.
Hence, the answer is option B.
Which one of the words given below is the right antonym for ‘alertness’ as used in the passage?
In the second paragraph, the author mentions, "a chemical substance called phenyl ethylene which acts like an amphetamine to increase mental alertness and physical energy."
In the context of the line, mental alertness means the ability to concentrate.
Among the options, option A is the best choice.

I doubt if I ________ resisted the temptation
The correct answer is "could have" because the sentence talks about whether it was possible to resist temptation in the past. "Would have" is used for imaginary situations, but it is not correct here. "Should have" means it was the right thing to do, but that’s not what the sentence is saying. "Will have" talks about the future, so it doesn’t fit. The best choice is "could have" because it expresses possibility in the past. The correct sentence is: "I doubt if I could have resisted the temptation."

After reading the passage given below, choose the best answer to each question that follows:
In contrast to traditional analyses of minority business, the sociological analysis contends that minority business ownership is a group-level phenomenon, in that it is largely dependent upon social-group resources for its development. Specifically. this analysis indicates that support networksplay critical role in starting and maintaining minority business enterprises by providing owners with a range of assistance, from the informal encouragementof family members and friends to dependable sources of labor andclientele from the owner's ethnic group. Suchself-help networks, which encourage and support ethnic minority entrepreneurs, consist of “primary” institutions, those closest to the individual in shaping his or her behavior and beliefs. They are characterized by the face-to-face association and cooperation of persons united by ties of mutual concern. They form an intermediate social level between the individual and larger “secondary”institutions based on impersonal relationships. Primary institutions comprising the support network include kinship, peer. and neighborhood or community subgroups. A major function of self-help networks is financial support. Most scholars agree that minority business owners have dependedprimarily on family funds and ethnic community resources for investmentcapital. Personal savings have been accumulated, often through frugal living habits that require sacrifices by the entire family and are thus a product of long-term family financial behavior. Additional loans andgifts from relatives, forthcoming because of group obligation rather than narrow investment calculation, have supplemented personal savings. Individual entrepreneurs do not necessarily rely on their kin because they cannot obtain financial backing from commercial resources. They may actually avoid banks because they assume that commercial institutions either cannot comprehend the special needs of minority enterprise or charge unreasonably high interest rates. Within the larger ethnic community, rotating credit associations have been usedto raise capital. These associations are informal clubs of friends and other trusted members of the ethnic group who make regular contributions to a fund that is given to each contributor in rotation. One author estimates that 40 percent of New York Chinatown firms established during 1900-1950 utilized such associations as their initial source of capital. However, recent immigrants andthird or fourth generationsof older groups now employrotating credit associations only occasionally to raise investment funds. Some groups, like Black Americans, found other means of financial support for their entrepreneurial efforts. The first Black-operated banks were created in the late nineteenth century as depositories for dues) collected from fraternal or lodge groups. which themselves had sprung from Black churches. Black banks made limited investments in other Black enterprises. Irish immigrants in American cities organized many building and loan associations to provide capital for home construction and purchase. They, in turn, provided work for many Irish home-building contractor firms. Other ethnic and minority groups followed similar practices in founding ethnic-directed financial institutions.
