Understanding

Application

The ratio of present ages of Ajay and Vijay is 2 : 3. 4 years ago the ratio of their ages was 3 : 5.

Suppose the present ages of Ajay and Vijay are 2x and 3x respectively.

So,

(2x – 4) : (3x – 4) = 3 : 5

10x – 20 = 9x – 12

x = 8

Hence,

Vijay's present age = 3x = 24 years
