      Present average age of Aman and Binny is 20 years and

      present age of Chirag is 4 years more and 6 years less than the present age of Aman and Binny, respectively. Find the present age of Chirag.
      A 15 years Correct Answer Incorrect Answer
      B 19 years Correct Answer Incorrect Answer
      C 22 years Correct Answer Incorrect Answer
      D 18 years Correct Answer Incorrect Answer
      E 21 years Correct Answer Incorrect Answer

      Solution

      Let the present age of Binny be 'x' years So, present age of Aman = {(20 X 2) - x} = (40 - x) years Now, according to the data given: 40 - x + 4 = x - 6 Or, 2x = 40 + 4 + 6 Or, 2x = 50 Or, x = 25 Present age of Chirag = (x - 6) = (25 - 6) = 19 years
