# What will be Excluded Number? If

The mean of five numbers is 18. If one number is excluded, their mean is 16. The excluded number is :

- 25
- 26
- 27
- 30

**Answer: (2) 26**

**Explanation:-**

The mean of five numbers = 18

Then, the sum of five numbers = 18 x 5 = 90

One new number is excluded.

Then, the new mean = 16

The sum of remaining number = 16 x 4 = 64

Excluded number = 90 – 64

= 26

Hence, the excluded is 26.
