Question
The ratio of A and B present age is 5:3. The product of
their ages is 1500. What will be the ratio of their ages after 2 years?Solution
Let their present age be 5x and 3x respectively. Product of their ages = 15x² = 1500 => x² = 100 => x = 10 Present age of A = 5x = 50 years Present age of B = 3x = 30 years Ratio of their ages after 2 years = (50+2) : (30+2) = 52:32 = 13:8
