Q.

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 ?                        


A. 16 Years B. 18 Years
C. 20 Years D. Can not be determined
E. None of these

Answer: Option A
Explaination:

 


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.
