Current age of Ritu and Rinki is in the ratio 3:4. 6 years back, the ratio of their ages was 2:3. What is the present age of Ritu?

Solution

Let their present ages be 3x and 4x.

Six years ago, their ages were (3x - 6) and (4x - 6).

So, according to the question:
(3x - 6) / (4x - 6) = 2 / 3

Cross multiplying,
3(3x - 6) = 2(4x - 6)

Simplifying,
9x - 18 = 8x - 12

x = 6

Therefore, Ritu’s present age = 3x = 18 years.

Answer: 18 years
