      Question

      The ratio of A and B present age is 3:2. The product of

      their ages is 2400. What will be the ratio of their ages after 5 years?
      A 17:11 Correct Answer Incorrect Answer
      B 19:9 Correct Answer Incorrect Answer
      C 17:7 Correct Answer Incorrect Answer
      D 13:9 Correct Answer Incorrect Answer

      Solution

      Let their present age be 3x and 2x respectively. Product of their ages = 6x² = 2400 => x² = 400 => x = 20 Present age of A = 3x = 60 years Present age of B = 2x = 40 years Ratio of their ages after 5 years = (60+5) : (40+5) = 65:45 = 13:9
