The average score of 7 players was initially recorded as 55. However, it was later discovered that a score of 35 had been mistakenly read as 53. Determine the correct average score.(Rounded up to two decimal places)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 52.43.
Average of 7 players = 55
Total score = 55 × 7 = 385
An error was made:
35 was wrongly recorded as 53 → extra 18 added
Correct total = 385 - 18 = 367
Correct average = 367 ÷ 7 = 52.43
