      Question

      The average age of A and B is 22 years. If A is to be

      replaced by C, the average would be 21 years. The average age of C and A is 23 years. Find the age of A.
      A 20 yr Correct Answer Incorrect Answer
      B 24 yr Correct Answer Incorrect Answer
      C 26 yr Correct Answer Incorrect Answer
      D 25 yr Correct Answer Incorrect Answer

      Solution

      A + B = 2 × 22 = 44 yr B + C = 2 × 21 = 42 yr C + A = 2 × 23 = 46 yr On adding all three, 2 (A + B + C) = 44 + 42 + 46 = 132 ⇒ A + B + C = 66 ∴ A = (A + B + C) – (B + C) = 66 – 42 = 24 yr
