      C 60 years Correct Answer Incorrect Answer
      D 66 years Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      Let present age of β€˜B’ be β€˜x’ years Present age of β€˜A’ = x Γ— 1.3 = β€˜1.3x’ years ATQ; (x + 8) + 9 = (1.3x + 8) Or, x + 17 = 1.3x + 8 Or, 9 = 0.3x Or, x = 30 So, present age of β€˜B’ = 30 years And, present age of β€˜A’ = 30 + 9 = 39 years Required sum = 39 + 30 = 69 years
