## Solving sample questions for Quantitative Ability:

1. What decimal of an hour is a minute?

A. .0166

B. .0256

C. .060

D. .000126

Explanation:

2. The H.C.F. of two numbers is 30 and the other two factors of their L.C.M. are 10 and 12. The larger of the two numbers is:

B. 320

C. 360

D. 345

Explanation:

Clearly, the numbers are (30 x 10) and (30 x 12).

Larger number = (30 x 12) = 360.

3. If half of one-fourth of a number is 13, then four-tenth of that number is:

A. 35.6

B. 36.5

C. 45.2

D. 41.6

Explanation:

Let the number be x.

Then, 1/2 of 1/4 of x=13

→ x=13*8 = 104

required number =4/10 * 104 = 41.6

4.If a man walks at 12 km/h instead of 9 km/h, he would have walked 15 km more. The actual distance traveled by him is:

A. 45km

B. 56km

C. 77km

D. 50km

Explanation:

Let the actual distance traveled be x km.

x/9 =(x+15)/12

12x = 9x + 135

3x = 135

x = 45 km.

5. A can do a piece of work in 8 days and B can do same work in 6 days. A and B undertook to do it for Rs. 3200. With the help of C, they completed the work in 3 days. How much is to be paid to C?

A. Rs. 500

B. Rs. 700

C. Rs. 400

D. Rs. 650

Explanation:

C's 1 day's work = 1/3 - (1/8 + 1/6 ) = 1/3 - 7/24 = 1/24

A's wages : B's wages : C's wages = 1/8 : 1/6 : 1/24 = 3 : 4 : 1

C's share (for 3 days) = Rs. ( 3 * 1/24 * 3200) = Rs. 400.

6. Two students A and B appeared for an examination. A secured 10 more marks than B which is equal to 60% of the sum of their marks. The marks obtained by A and B  are:

A. 35, 325

B. 39, 29

C. 42, 32

D. 30, 20

Explanation:

Let their marks be (x + 10) and x.

Then, x + 10 = (60 / 100) (x + 10 + x)

→ 10(x + 10) = 6(2x + 10)

→ 2x = 40

→ x = 20

Hence, their marks are 30 and 20

7. A mother said to his son, "I was as old as you are at the present at the time of your birth". If the mother's age is 40 years now, the son's age 3 years back was:

A. 14 years

B. 17 years

C. 33 years

D. 40 years

Explanation:

Let the son's present age be x years. Then, (40 - x) = x

2x = 40.

x = 20.

Son's age 3 years back (20 - 3) = 17 years.

8. In how many ways can the letters of the word 'MANAGE' be arranged?

A. 360

B. 144

C. 256

D 720

Explanation:

The word 'MANAGE' contains 6 letters, namely 1M,2A,1N,1G, and 1N.

The required number of ways = 6! / (1!)(2!)(1!)(1!)(1!) = 360

9.if log a/b + log b/a = log (a+b), then

A. a + b = 1

B. a - b = 1

C. a = b

D. a2 - b2 = 1

Explanation:

According to formulae:

log a/b + log b/a = log a+b

log a+b = log (a/b * b/a) = log 1

Hence, a + b = 1.
