Question
5 years ago ratio of the ages of the two persons A and B
was 3:1. 3 years hence the ratio of their ages will be 7:3. Find the present age of B.Solution
5 years ago, Let A’s age be 3x and B’s age be x. According to the question, 3 years hence, => (3x + 8)/(x + 8) = 7/3 => 9x + 24 = 7x + 56 => x = 16 Present age of B = x + 5 = 16 + 5 = 21 years
