      Question

      Present average age of P and Q is 24 years. Present age

      of R is 4 years more than P and 8 years less than Q. Find the ratio of present age of P to the present age of Q.
      A 5 : 7 Correct Answer Incorrect Answer
      B 2 : 3 Correct Answer Incorrect Answer
      C 3 : 5 Correct Answer Incorrect Answer
      D 4 : 5 Correct Answer Incorrect Answer

      Solution

      Let the present age of Q be 'x' years So, present age of P = {(24 X 2) - x} = (48 - x) years Now, according to the data given: 48 - x + 4 = x - 8 Or, 2x = 48 + 4 + 8 Or, 2x = 60 Or, x = 30 (Q's age) Present age of P = (48 - 30) = 18 years Required Ratio (P : Q) = 18 : 30 = 3 : 5
