Question
The ratio of A and B present age is 5:2. The product of
their ages is 9000. What will be the ratio of their ages after 3 years?Solution
Let their present age be 5x and 2x respectively. Product of their ages = 10x² = 9000 => x² = 900 => x = 30 Present age of A = 5x = 150 years Present age of B = 2x = 60 years Ratio of their ages after 3 years = (150+3) : (60+3) = 153:63 = 17:7
