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 Sagar's age at present?

Answer 1

so the present age of sagar is 16

Answer 2

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

Then,(6x + 6) + 4/(5x + 6) + 4 = 11/10

10(6x + 10) = 11(5x + 10)

5x = 10

x = 2.

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