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

A 18 years
B 20 years
C 16 years
D 22 years

Correct Answer: 16 years

Let the ages of Kunal and Sugar 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 = 1 ∴ Sagar's present age = (5x + 6) = 16 years.
