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?	Choose the correct answer:
A) 14
B) 15
C) 16
D) 17
E) 18
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.   ANSWERS : 16
