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.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
