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? Options:	A) 16	B) 20	C) 21	D) 10	E) 27
Let the ages of Kunal and Sagar 6 years ago be 6x and 5x years respectively.   Then,	((6x + 6) + 4)*10=	11*((5x + 6) + 4)   10(6x + 10) = 11(5x + 10)   5x = 10   x = 2.   Sagar's present age = (5x + 6) = 16 years   16ns- 16
