(a) 0.93

(b) 0.95

(c) 0.89

(d) 0.90

Answer: (a) 0.93

Explanation: P(E) + P(not E) = 1

Since, P(E) = 0.05

So, P(not E) = 1 – P(E)

Or, P(not E) = 1 – 0.07

∴ P(not E) = 0.93 - A dice is thrown in the air. The probability of getting odd numbers is

(a) 1/2

(b) 3/2

(c) 3

(d) 4

Answer: (a) 1/2

Explanation: A dice has six faces having values 1, 2, 3, 4, 5 and 6.

There are three odd numbers and three even numbers.

Therefore, the probability of getting only odd numbers is = 3/6 = 1/2 - Two players, Sangeeta and Reshma, play a tennis match. It is known that the probability of Sangeeta winning the match is 0.62. The probability of Reshma winning the match is

(a) 0.62

(b) 0.38

(c) 0.58

(d) 0.42

Answer: (b) 0.38

Explanation:

Probability of Sangeeta’s winning = P(S) = 0.62

Probability of Reshma’s winning = P(R) = 1 – P(S) {since events R and S are complementary}

= 1 – 0.62

= 0.38 - The mode and mean is given by 7 and 8, respectively. Then the median is:

(a) 1/13

(b) 13/3

(c) 23/3

(d) 33

Answer: (c) 23/3

Explanation: Using Empirical formula,

Mode = 3Median – 2 Mean

3Median = Mode + 2Mean

Median = (Mode + 2Mean)/3

Median = [7 + 2(8)]/3 = (7 + 16)/3 = 23/3 - If the mean of first n natural numbers is 3n/5, then the value of n is:

(a) 3

(b) 4

(c) 5

(d) 6

Answer: (c) 5

Explanation: Sum of natural numbers = n(n + 1)/2

Given, mean = 3n/5

Mean = sum of natural numbers/n

3n/5 = n(n + 1)/2n

3n/5 = (n + 1)/2

6n = 5n + 5

n = 5 - The pairs of equations 9x + 3y + 12 = 0 and 18x + 6y + 26 = 0 have

(a) Unique solution

(b) Exactly two solutions

(c) Infinitely many solutions

(d) No solution

Answer: (d) No solution

Explanation: Given, 9x + 3y + 12 = 0 and 18x + 6y + 26 = 0

a1/a2 = 9/18 = 1/2

b1/b2 = 3/6 = 1/2

c1/c2 = 12/26 = 6/13

Since, a1/a2 = b1/b2 ≠ c1/c2

So, the pairs of equations are parallel and the lines never intersect each other at any point, therefore there is no possible solution. - A fraction becomes 1/3 when 1 is subtracted from the numerator and it becomes 1/4 when 8 is added to its denominator. The fraction obtained is:

(a) 3/12

(b) 4/12

(c) 5/12

(d) 7/12

Answer: (c) 5/12

Explanation: Let the fraction be x/y

So, as per the question given,

(x -1)/y = 1/3 => 3x – y = 3…………………(1)

x/(y + 8) = 1/4 => 4x –y =8 ………………..(2)

Subtracting equation (1) from (2), we get

x = 5 ………………………………………….(3)

Using this value in equation (2), we get,

4×5 – y = 8

y= 12

Therefore, the fraction is 5/12. - The roots of 100×2 – 20x + 1 = 0 is:

(a) 1/20 and 1/20

(b) 1/10 and 1/20

(c) 1/10 and 1/10

(d) None of the above

Answer: (c) 1/10 and 1/10

Explanation: Given, 100×2 – 20x + 1=0

100×2 – 10x – 10x + 1 = 0

10x(10x – 1) -1(10x – 1) = 0

(10x – 1)2 = 0

∴ (10x – 1) = 0 or (10x – 1) = 0

⇒x = 1/10 or x = 1/10 - If ½ is a root of the quadratic equation x2-mx-5/4=0, then value of m is:

(a) 2

(b) -2

(c) -3

(d) 3

Answer: (b) -2

Explanation: Given x=½ as root of equation x2-mx-5/4=0.

(½)2 – m(½) – 5/4 = 0

¼-m/2-5/4=0

m=-2 - n² – 1 is divisible by 8, if n is

(a) an integer

(b) a natural number

(c) an odd integer

(d) an even integer

Answer: (c) an odd integer

Explanation:

We know that an odd number in the form (2Q + 1) where Q is a natural number ,

so, n² -1 = (2Q + 1)² -1

= 4Q² + 4Q + 1 -1

= 4Q² + 4Q

Substituting Q = 1, 2,…

When Q = 1,

4Q² + 4Q = 4(1)² + 4(1) = 4 + 4 = 8 , it is divisible by 8.

When Q = 2,

4Q² + 4Q = 4(2)² + 4(2) =16 + 8 = 24, it is also divisible by 8 .

When Q = 3,

4Q² + 4Q = 4(3)² + 4(3) = 36 + 12 = 48 , divisible by 8

It is concluded that 4Q² + 4Q is divisible by 8 for all natural numbers.

Hence, n² -1 is divisible by 8 for all odd values of n. - Find the odd one out.

a) Figure A

b) Figure B

c) Figure C

d) Figure D

Answer: c

Explanation: Here, figure A, figure B and figure D follows a pattern of symbols which are present on its corners that is figure B is 90° rotated representation of figure A. And figure D is the mirror image of figure A. But figure C is neither rotated representation of figure A, nor mirror image of figure A (i.e. not related with figure A). Hence, figure C is the answer. - In a certain code “DELHI” is written as “92675” and “BOMBAY” is written as “431408”. How can “MADRAS” be written in that code?

a) 13241295

b) 61374

c) 109704

d) 261

Answer: c

Explanation: Here, from DELHI AND BOMBAY we can predict that M→1, A→0, D→9. And no other option has 6 digits to code MADRAS.

Therefore MADRAS→109704

Hence, the answer is 109704. - Introducing a man, a woman said, “His Wife is the only daughter of my mother”. How is that man related to the woman?

a) Husband

b) Sister

c) Wife

d) Mother

Answer: a

Explanation: Here, the woman’s mother has only one daughter, who is the wife of that man, i.e. the woman herself is his wife.

Hence, the answer is Husband. - Milly introduced a boy as the son of the only daughter of the mother of her maternal uncle. How is Milly related to that boy?

a) Sister

b) Brother

c) Son

d) Nephew

Answer: a

Explanation: Here, it is clear that the boy’s mother is the only daughter of her mother, who is also the mother of Milly’s maternal uncle i.e. the boy’s mother and Milly’s mother are same i.e. Milly and the boy are siblings.

Hence the answer is Sister. - India : ISRO :: Japan : ?

a) NASA

b) ESA

c) JAXA

d) TESLA

Answer: c

Explanation: From analyzing the left side, we can conclude that ISRO is the space research organization of India.

a) 135

b) 75

c) 195

d) 175

Answer: d

Explanation: Here, the number of students who study any of these subject is:-

200 + 85 – 60 = 225

Since, total number of students is 400, therefore, the number of students who did not study any of these subjects is:-

400 – 225 = 175

Hence, 175 is the answer. - A cowherd had 23 cows. All but seven died. How many will he have left?

a) 111

b) 53

c) 121

d) 181

Answer: c

Explanation: Here, opposite numbers are obtained by multiplying the number by 11, i.e.

35*11=385;

11*11=121;

Hence the answer is 121.
