Question
The ratio of A and B present age is 5:3. The product of
their ages is 6000. What will be the ratio of their ages after 4 years?Solution
Let their present age be 5x and 3x respectively. Product of their ages = 15x² = 6000 => x² = 400 => x = 20 Present age of A = 5x = 100 years Present age of B = 3x = 60 years Ratio of their ages after 4 years = (100+4) : (60+4) = 104:64 = 13:8
