      B 50 Correct Answer Incorrect Answer
      C 45 Correct Answer Incorrect Answer
      D 60 Correct Answer Incorrect Answer
      E 55 Correct Answer Incorrect Answer

      Solution

      Marks obtained by Rahul and Tarun be ‘6x’ and ‘5x’ respectively.

      So, (6x + 4)/(5x – 5) = 7/5

      6x + 4 = 7x – 7

      x = 11

      Marks obtained by Tarun = 5x = 55
