Question

The mean of 5 numbers is 27. If one number is excluded , their mean is 25. Find the excluded number.

Answer 1

Answer:

The mean of 5 numbers is 27.

So sum of the numbers = 27 × 5 = 135

Let x number is excluded

Then

Remaining numbers = 4 & sum = 25×4 = 100

So

135 - x = 100

x = 135 - 100 = 35

So the required number is 35
