      E None of these Correct Answer Incorrect Answer

      Solution

      ATQ,

      T – 6 = 1/2 * (T + 14)

      2T – 12 = T + 14

      T = 26

      Present age of T = 26 years

      S + 10 + T + 10 = 84

      S + 10 + 26 + 10 = 84

      S = 84 – 46 = 38 years

      R + 3 = 3/2 * (38 + 6)

      R + 3 = 3/2 * 44

      R = 66 – 3 = 63 years
