Six years ago, the ratio of 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?	Choose the correct choice from the following answers:
A) 16 years	B) 18 years	C) 88 years	D) 17 years	E) 13 years
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) =&gt; x = 2   Sagar's present age = (5x + 6) = 16 years.   16 yearsnswer: 16 years
