      E None of these Correct Answer Incorrect Answer

      Solution

      Let the present ages of β€˜A’ and β€˜B’ be 3x years and 4x years, respectively Therefore, 4x + 2 = 10 Or, 2x = 8 Or, x = 4 Sum of present ages of β€˜A’ and β€˜B’ = 3x + 4x = 14 years Sum of present ages of β€˜A’, β€œB’ and β€˜C’ = 22 Γ— 3 = 66 years Therefore, present age of β€˜C’ = 66 – 14 = 52 years
