      Question

      Arun's average score across six subjects, including

      English and Mathematics, is recorded as 55. However, there was an error in reporting his marks for English and Mathematics: instead of the correct scores of 45 and 75, they were incorrectly noted as 54 and 27. Determine Arun's actual average score in these six subjects.
      A 64 Correct Answer Incorrect Answer
      B 61.5 Correct Answer Incorrect Answer
      C 57.5 Correct Answer Incorrect Answer
      D 65 Correct Answer Incorrect Answer

      Solution

      Sum of marks scored by Arun according to the wrongly printed mark sheet = 55 X 6 = 330 Actual sum of marks scored by Arun = 330 - (54 + 27) + (45 + 75) = 369 So, actual average marks scored by Arun = 369 ÷ 6 = 61.5
