      If 13 years hence from now, β€˜B’ will be 12 years younger than β€˜A’, then find the sum of present ages of β€˜A’ and β€˜B’.

      C 53 years Correct Answer Incorrect Answer
      D 56 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— 1.60 = β€˜1.60x’ years ATQ; (x + 13) + 12 = (1.60x + 13) Or, x + 25 = 1.60x + 13 Or, 12 = 0.60x Or, x = 20 So, present age of β€˜B’ = 20 years And, present age of β€˜A’ = 20 + 12 = 32 years Required sum = 20 + 32 = 52 years
