The average marks of four subjects is 120. If 33 was misread as 13 during the calculation, what will be the correct average?
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
