      A 30 Correct Answer Incorrect Answer
      B 15 Correct Answer Incorrect Answer
      C 25 Correct Answer Incorrect Answer
      D 20 Correct Answer Incorrect Answer

      Solution

      ⇒ A = (1 + 4/5)B = 9B/5 ⇒ C = (100% - 48 4/7%)(A + B) = 51 3/7% (9B/5 + B) ⇒ C = (3.6/7) × (14B/5) = 7.2B/5 Difference between A and C = 1.8B/5 ⇒ Percentage = (1.8B/5)/(9B/5) × 100 = 0.2 × 100 = 20% ∴ The required percentage = 20%
