The ratio of Kamal's and Sagar's ages was 6:5 six years ago. It will be 11:10 after four years. What is Sagar's current age?
A
18
B
16
C
20
D
None of these
Correct Option:
B
Explanation
Six years ago, Kamal:Sagar = 6:5, so let their ages then be 6x and 5x. Four years from now is 10 years after that reference point. Therefore, (6x + 10)/(5x + 10) = 11/10. Solving gives x = 2. Sagar's age six years ago was 10, so his present age is 16 years.
