The average marks of four subjects is 120. If 33 was misread as 13 during the calculation, what will be the correct average?
Answer: 125
Explanation
The average marks of four subjects is 120, so the total marks are:
120 x 4 = 480
If 33 was misread as 13, that means the actual total marks should be:
480 - 13 + 33 = 500
Now, let's calculate the correct average:
Correct average = Total marks / Number of subjects
= 500 / 4
= 125
