Question

Six years ago, the ratio of the ages of Kunal and Sagar was 6 : 5. Four years hence, the ratio of their ages will be 11 : 10. What is Sagars age at present?

Answer: Option A

Let the ages of Kunal and Sagar 6 years ago be 6x and 5x years respectively.

Then, \(\frac{(6x+6)+4}{(5x+6)+4} = \frac{11}{10}\)

10(6x + 10) = 11(5x + 10)

5x = 10

x = 2.

So Sagar's present age = (5x + 6) = 16 years.
