Ages 15Q

15.  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 

A.24                    B.29

C.26                   D.32

Answer:          24

Explanation:  

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.
