The average of five numbers is 27. If one number is excluded, the average becomes 25. The excluded number is _______?
- 27
- 35
- 30
- None of these
Explanation
Initially, the average of five numbers is 27, so the sum of these five numbers is:
5 x 27 = 135
If one number is excluded, the average becomes 25, which means the sum of the remaining four numbers is:
4 x 25 = 100
Now, let's find the excluded number by subtracting the sum of the remaining four numbers from the initial sum:
135 - 100 = 35
So, the excluded number is 35.
