Average of 90 results is 38. If 4 is subtracted from each result, then what will be the new average of the results?

Correct option is B

Given:
Average of 90 results = 38
Formula Used:
When a constant value is subtracted from each item, the average decreases by that value.
Solution:
Original average = 38
If 4 is subtracted from each result, the new average will be 38 - 4 = 34
Therefore, the new average of the results is 34.
