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

### Note

A.M. of 75 numbers = 35.

Sum of 75 numbers = (75 × 35) = 2625.

Total increase = (75 × 5) = 375.

Increased sum = (2625 + 375) = 3000.

**Increased average = (3000/75) = 40**
