Answers & Solutions:<\/strong><\/span><\/p>\n

1)\u00a0Answer\u00a0(A)<\/strong><\/p>\n

Statement I: $(x-23)^2 = (y-23)^2$
\n=> $x-23 = \\pm (y-23)$
\n=> x=y or x+y = 46
\nStatement II: $(x+y)(\\frac{1}{x} + \\frac{1}{y}) – 4 = 0$
\n=> $\\frac{(x+y)^2}{xy} = 4 $
\n=> $\\frac{x^2 + y^2 + 2xy}{xy} = 4 $
\n=> $\\frac{x^2 + y^2}{xy} = 2 $ or $x^2 + y^2 -2xy = 0$
\n=> $(x-y)^2 = 0$ or x=y<\/p>\n

We can see that the question can be answered using statement 2 alone. Thus, A is the correct answer.<\/p>\n

2)\u00a0Answer\u00a0(A)<\/strong><\/p>\n

The numbers must range from [5,13]
\nSince both 5 and 13 are included in the six numbers, the other 4 numbers must be among 6, 7, 8, 9, 10, 11 and 12.
\nLet\u2019s consider statement 1. So, the sum of the six numbers is 11 more than a perfect square. Min and Max sum of the six numbers can be 48 and 60. So the only perfect square that we should consider is 49. So, the sum of the six numbers should be 49+11 = 60
\nThis is only possible when the six numbers are 5, 9, 10, 11, 12, 13. Since the sum of the numbers is known, the average can be calculated.
\nStatement 2: So, exactly 3 of the six numbers are prime and the sum of the numbers is also prime.
\nNow, 5 and 13 are both prime. So, the third number should be either 7 or 11.
\nLet\u2019s consider 7 as the third prime.
\nSo, the sum should be 5+7+13 + (Sum of 3 composite numbers among 6, 8, 9, 10, and 12) or 25 + (Sum of 3 composite numbers among 6, 8, 9, 10, and 12) prime.
\nBut, none of the combination yields a prime sum.
\nLet\u2019s assume 11 is the third prime.
\nSo, the sum should be 5+11+13 + (Sum of 3 composite numbers among 6, 8, 9, 10, and 12) or 29 + (Sum of 3 composite numbers among 6, 8, 9, 10, and 12) prime.
\nSo, there are 2 possible cases when sum is prime.
\n(i) When the numbers are (5+11+13+6+8+10) where the sum is 53, and
\n(ii) When the numbers are (5+11+13+8+10+12) where the sum is 59
\nWe can see that the average will be different in both the cases. So, II is not sufficient.
\nThus, A is the correct answer.<\/p>\n

3)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

From I, the only possible age of Shyam is 9 years (Since the difference between his present age and his age 5 years ago are perfect squares with a difference of 5)
\nSince we know Shyam\u2019s age we can easily find the Ram\u2019s age as well. 5 years ago Ram’s age was twice the age of Shyam. So Shyam’s age would have been 4. Thus, Ram’s age would have been 8. Thus his present age would be 13.
\nThus I alone is sufficient to answer the question.
\nFrom II, we know that Moan\u2019s age is 7. Thus, Ram\u2019s age would be 35.
\nHence even statement II alone is sufficient. Hence the correct answer is option B.<\/p>\n

4)\u00a0Answer\u00a0(D)<\/strong><\/p>\n

From the statements we know that the decreasing order of heights is:
\nC>D>A and
\nA>B<C
\nCombining these statements we know that, D>A>B. So B is shorter than D.<\/p>\n

5)\u00a0Answer\u00a0(A)<\/strong><\/p>\n

From statement 1 we know that their speeds are v1 and v2. So the distance will be (v1+v2)*t.
\nFrom the second statement we only know the ratio of the speeds and without the absolute values we cannot compute the distance between them.<\/p>\n

6)\u00a0Answer\u00a0(E)<\/strong><\/p>\n

x(y+2)
\nI: x and y are prime.
\nSo, if any of x and y is 2, x(y+2) is a even number. While, when both are odd x(y+2) is also odd.
\nII: y>11
\nThis is clearly not sufficient as even y will yield even number and odd x and y will yield odd number.
\nUsing I and II together:
\nSo, x=2 then the number is even, and when x is odd prime number, the number is odd.
\nThus, the question cannot be answered even by using both statements together.<\/p>\n

7)\u00a0Answer\u00a0(E)<\/strong><\/p>\n

I: If 16a is an integer, a can be 1\/2, 1\/4, 1\/8, 1\/16 or 0.5, 0.25, 0.125, 0.0625
\nThus, from this statement, we can\u2019t infer that the tenth decimal digit is non-zero.
\nII: If 32a is an integer, a can be 1\/2, 1\/4, 1\/8, 1\/16, 1\/32 or 0.5, 0.25, 0.125, 0.0625, 0.03125
\nThus, from this statement, we can\u2019t infer that the tenth decimal digit is non-zero.
\nIf both statements are used, we can infer that \u2018a\u2019 is one among 0.5, 0.25, 0.125, 0.0625.
\nBut, even then we can\u2019t conclude that the tenth decimal digit is non-zero since 0.0625 has 0 has tenth decimal digit.
\nThus, the answer is E.<\/p>\n

8)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

Let the total number of students in 12th standard be x. Then total students in Commerce = .4x and students in Science = .6x
\nNumber of females in the Science stream = .6x $\\times$2 = .12x Thus, no. of males in the Science stream = .48x
\nFrom Statement I, .48x – .12x = 36
\n=> .36x = 36. Thus, x = 100. From this we cannot find the percentage of males in Commerce stream.
\nFrom statement II, Total girls in 12th = .4x
\nThus, total girls in Commerce stream = .4x – .12x = .28x
\nThus, total males in Commerce stream = Total students in Commerce – girls in Commerce = .4x – .28x = .12x
\nFrom this we can find the percent of male students in Commerce. Thus, B alone is enough to answer the given question.<\/p>\n

9)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

We have to find whether the given statements are enough to find whether X is divisible by 12 i.e. X is divisible by both 3 and 4.
\nFrom statement I, X is of the form 16m + 4. 16m + 4 is divisible by 4 but we cannot know whether X is divisible by 3 or not. Thus, statement I alone is not sufficient to answer the given question.
\nFrom statement II, X is of the form 18k + 6. 18k + 6 is divisible by 3 but we cannot know whether X is divisible by 4 or not. Thus, statement II alone is not sufficient sufficient to answer the given question.
\nIf we combine both the statements we find that X is divisible by both 3 and 4. Thus, both statements together can answer if X is divisible by 12. Thus, C is the right choice.<\/p>\n

10)\u00a0Answer\u00a0(E)<\/strong><\/p>\n

From statement I alone, we cannot determine the position of anyone.
\nFrom statement II alone, we can infer some structure, but still we can’t conclude who is the shortest.
\nBut if combine both the statements, then from statement II, we can be sure that B is either at 1st position on at 2nd position. But from statement I, the possibility of B being at the first position can be ruled out. Hence B stands at 2nd position. So C is at fifth and F is at 6th.
\nHence if we combine both the statements together, then we can answer the given question.<\/p>\n

11)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

We are given that N is a two digit number having odd number of factors.
\nSo we can say that N is a perfect square.
\n2 digit perfect squares are 16, 25, 36, 49, 64, 81
\nThe sum of the digits of these numbers is as follow
\n16 – 7
\n25 – 7
\n36 – 9
\n49 – 13
\n64 – 10
\n81 – 9
\nFrom statement I we can rule out 9 but we still have 4 possibilities left. Hence we cannot answer the question from statement I alone.
\nFrom statement II, we know that the sum of the digits is even. There\u2019s only one sum which is even. i.e 10 Hence from we cannot answer the question using statement II alone.<\/p>\n

12)\u00a0Answer\u00a0(D)<\/strong><\/p>\n

The number of students who don\u2019t play any instrument has not been mentioned in the question or in the two statements. Without it, the number of students who play all the three instruments cannot be found out. Thus, the answer is D.<\/p>\n

13)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

To find the relation between x and y we first have to eliminate z.
\nMultiplying the equation from Statement 1 by 5 we get,
\n5x+15y+20z = 400 —- (1)
\nMultiplying the equation from Statement 2 by 4 we get,
\n12x+8y+20z = 400 —- (2)
\nSubtracting equation (1) from (2) we get, x = y.<\/p>\n

14)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

Let a m\/s be the speed of the faster person and b m\/s be the speed of the slower person
\nIn statement I, only the length of the track is given. We cannot find the ratio of their speeds from this information alone.
\nIn statement II, the distance travelled by the slower person is given but not the distance of the faster person. Thus, again we cannot find the ratio of their speeds from this information alone.
\nIf we combine both information we get, the length of track is 450m and distance travelled by the slower person after six meetings as 3700m.
\nWhen the two people meet for the first time, the faster one travels extra distance equal to the length of the track. Thus, the distance travelled by the faster persons after six meetings = 3700+ 450 x 6 = 6400m
\nThus, in equal time the faster one and the slower one travels 6400m and 3700m respectively.
\nThus, the ratio of their speeds = 6400\/3700 = 64 : 37
\nThus, the question can be answered if we combine both the statements together.<\/p>\n

15)\u00a0Answer\u00a0(A)<\/strong><\/p>\n

Let the fixed income be I, performance bonus be B and the total salary be S.
\n$S = I+B$<\/p>\n

From Statement 1 we know that, $I+\\frac{13B}{10}=\\frac{11S}{10}$
\n=> $\\frac{10I}{11}+\\frac{13B}{11}=S=B+I$
\n=> $2B = I$
\nFrom this we can say that the banker\u2019s fixed income accounted for more than 50% of his salary. Hence the question can be answered using Statement 1 alone.<\/p>\n

From Statement 2 we just know that the difference between his fixed income and performance bonus is half that of his fixed income but we do not know which one is higher. The answer to the question asked differs depending on which is higher. So it cannot be answered using Statement 2 alone.<\/p>\n

16)\u00a0Answer\u00a0(D)<\/strong><\/p>\n

According to Statement 1, either x<0 or x>1. When x belongs to (-1,0) $x^3>x$ and when x<-1 $x^3<x$.<\/p>\n

According to Statement 2, x<0. Again we can use the same above example. So Statement 2 is not sufficient.<\/p>\n

Hence both the statements together are also not sufficient to answer the question.<\/p>\n

17)\u00a0Answer\u00a0(A)<\/strong><\/p>\n

Using Statement 1 we can answer the number of people who eat pizza as we know the total population and also the number of people who eat burger.
\nBut in Statement 2 the total population of City A is not given and is thus not sufficient to answer the question.<\/p>\n

Hence Statement 1 alone is sufficient to answer the question.<\/p>\n

18)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

Let a m\/s be the speed of the faster person and b m\/s be the speed of the slower person
\nIn statement I, only the length of the track is given. We cannot find the ratio of their speeds from this information alone.
\nIn statement II, the distance travelled by the slower person is given but not the distance of the faster person. Thus, again we cannot find the ratio of their speeds from this information alone.
\nIf we combine both information we get, the length of track is 450m and distance travelled by the slower person after six meetings as 3700m.
\nWhen the two people meet for the first time, the faster one travels extra distance equal to the length of the track. Thus, the distance travelled by the faster persons after six meetings = 3700+ 450 x 6 = 6400m
\nThus, in equal time the faster one and the slower one travels 6400m and 3700m respectively.
\nThus, the ratio of their speeds = 6400\/3700 = 64 : 37
\nThus, the question can be answered if we combine both the statements together.<\/p>\n

19)\u00a0Answer\u00a0(A)<\/strong><\/p>\n

Let the fixed income be I, performance bonus be B and the total salary be S.
\n$S = I+B$<\/p>\n

From Statement 1 we know that, $I+\\frac{13B}{10}=\\frac{11S}{10}$
\n=> $\\frac{10I}{11}+\\frac{13B}{11}=S=B+I$

20)\u00a0Answer\u00a0(D)<\/strong><\/p>\n

According to Statement 1, either x<0 or x>1. When x belongs to (-1,0) $x^3>x$ and when x<-1 $x^3<x$.<\/p>\n

According to Statement 2, x<0. Again we can use the same above example. So Statement 2 is not sufficient.<\/p>\n
