The ratio of A and B present age is 8:5. The product of
their ages is 4000. What will be the ratio of their ages after 5 years?Solution
Let their present age be 8x and 5x respectively. Product of their ages = 40x² = 4000 => x² = 100 => x = 10 Present age of A = 8x = 80 years Present age of B = 5x = 50 years Ratio of their ages after 5 years = (80+5) : (50+5) = 85:55 = 17:11
