1. Ten years ago, P was half of Q in age. If the ratio of their present ages is 3:4, what will be the total of their present ages

A) 35

B) 34

C) 45

D) 25

Ans. A

Let the present age of P and Q be 3x and 4x respectively.

Ten years ago, P was half of Q in age

=> 2(3x ? 10) = (4x ? 10)

=> 6x ? 20 = 4x ? 10

=> 2x = 10

=> x = 5

2. The total age of A and B is 12 years more than the total age of B and C. C is how many year younger than A

A) 11

B) 12

C) 13

D) 14

Ans. B

Given that A+B = 12 + B + C

=> A ? C = 12 + B ? B = 12

=> C is younger than A by 12 years

3. The ages of two persons differ by 16 years. 6 years ago, the elder one was 3 times as old as the younger one. What are their present ages of the elder person

A) 15

B) 20

C) 25

D) 30

Ans. D

Let’s take the present age of the elder person = x

and the present age of the younger person = x ? 16

(x ? 6) = 3 (x-16-6)

=> x ? 6 = 3x ? 66

=> 2x = 60

=> x = 60/2 = 30

4. The ages of two persons differ by 20 years. If 5 years ago, the elder one be 5 times as old as the younger one, their present ages (in years) are respectively

A) 20,20

B) 20,10

C) 25,15

D) 30,10

Ans. D

Let their ages be x and (x + 20) years.

5 (x – 5) = (x + 20 – 5) or 4x = 40 or x = 10.

Their present ages are 30 years and 10 years

5. Ratio between Rahul and Deepak is 4:3, After 6 Years Rahul age will be 26 years. What is Deepak present age.

A) 14

B) 15

C) 20

D) 22

Ans. B

Present age is 4x and 3x,

=> 4x + 6 = 26 => x = 5

So Deepak age is = 3(5) = 15
