Question

The ratio of present ages of Hema and Chinnu is 13:17. Four years ago the ratio of their ages was 11:15. What will be the ratio of their ages six years hence ?
A) 3 : 7
B) 7 : 9
C) 4 : 5
D) 1 : 3

Answer 1

Answer: 4  :  5

Step-by-step explanation:

Let their present ages be 13x and 17x.

Then, 13x-4/17x-4 = 11/15.

Solving this, we get x = 2.

Required ratio = 13x2 + 6/17x2 + 6

                          = 32/40

                            = 4/5.
