The ratio of the present ages of A to B is 5 : 3. The ratio of A’s age 4 years ago to B’s age 4 years hence is 1 : 1. What is the ratio of A’s age 4 years hence to B’s age 4 years ago?

3 : 2

5 : 2

3 : 1

2 : 3

Explanation:

Let A’s present age = 5x, and B’s = 3x
Ratio of A’s age 4 years ago to B’s age 4 years hence is 1 : 1. So
(5x-4)/(3x+4) = 1/1
Solve x = 4
So A’s present age = 20, and B’s = 12
Required ratio = (20+4) : (12-4) = 3:1
