1. What is Kishore present age, if after 30 years his age will be 15times of his age 15 years back.

A. 18 yrs

B. 18.2 yrs

C. 19 yrs

D. 20.2 yrs

View Answer

Ans : B

Explanation: Let kishore’s present age be x
kishore’s age before 15 years = (x - 15)
kishore’s’s age after 30 years = (x + 30)
We are given that,
kishore’s’s age after 30 years (x + 30) is 15 times his age 15 years back (x – 15)
Therefore,
(x + 30) = 15 (x – 15)
Solving the equation, we get
x + 30 =15x –225
14x = 255
x = 18.2 years

2. The father's age 7years ago was 11 times the age of his daughter. At present the father's age is 7 times

C. 18.5 yrs

D. 19 yrs

View Answer

Ans : A

Explanation: At present the father's age is 7 times that of his daughter

i.e. Father's present age = 7x.

Father's age 7 years ago was 11 times the age of his daughter

(7x – 7) = 11 * (x – 7)

x = 17.5 years,

The daughter's present age = 17.5 years

3. Mani is 32years older than his son Dinesh. In 4 years, his age will be twice the age of his son. The present
age of his son is

A. 20 yrs

B. 24 yrs

C. 28 yrs

D. 32 yrs

View Answer

Ans : C

Explanation: Let the son's present age be x years.

Then, mani's present age = (x + 32) years

=> x + 36 = 2x + 8

So, x = 28

4. Ratio of ages of three girls are 5:8:10, six years ago, the sum of their ages was 28. Find their present

D. 10,12,16

View Answer

Ans : A

Explanation: Let the present ages are 5x, 8x, 10x.

=> (5x-6) + (8x-6) + (10x-6) = 28

=> 23x = 46

=> x = 2

So their present ages are: 10,16,20

5. Shyam is younger than Sharuk by 22 years. If the ratio of their ages is 5:7, find the age of Shyam

A. 55

B. 77

C. 66

D. 88

View Answer

Ans : A

Explanation: If sharuk age is x, then Shyam age is x-22,

so (x-22)/x = 5/7

=> 2x = 154

=> x = 77

So shyam age is 77 - 22 = 55

54:60

9:10
