The average of 36 numbers was found to be 45. Later, it was detected that 84 was misread as 48. Find the correct average of the given numbers.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 46
Given that
The average of 36 numbers = 45
The sum of 36 numbers = 45 × 36 = 1620
Later, it was detected that 84 was misread as 48
According to the question
The correct sum of 36 numbers = 1620 - 48 + 84 = 1656
Hence, the required average = 1656/36 = 46
