If the arithmetic mean of seventy five numbers is 35. If each number is increased by 5, then mean of new number is ____?

Correct Answer: B. 40

To find the new mean after increasing each number by 5, you can follow these steps:
1. Original mean: 35
2. Number of values: 75
When each number is increased by 5, the new mean will be:
New Mean=Original Mean+5
New Mean=35+5=40
So the correct answer is B. 40.
