Q.

The ratio of the ages of Swati and Varun is 2: 5. After 8 years, their ages will be in the ratio of 1 : 2. The difference in their present ages (in years) is ?                          [C.B.I 1993]
A. 24 B. 29
C. 26 D. 32

Answer: Option A
Explaination:

 


Let Swati age = 2x & Varuns age = 5x.


((2x + 8) / (5x + 8) )= (1/2) hence 2(2x+8) = (5x+8) so x=8.

Swatis age = 16 years & Varun's age =40 years.

Difference of their ages = 24 years.
