The average of 50 numbers is 38. If two numbers, namely 45 and 55 are discarded, the average of the remaining numbers is
-
- 37.5
- 37.9
- 36.5
- 37.0
- 37.5
Correct Option: A
Here , The average of 50 numbers = 38
Sum of 50 numbers = 50 × 38 = 1900
If two numbers, namely 45 and 55 are discarded , then Sum of 48 numbers = 1900 – 45 – 55 = 1800
∴ Required average = 1800 ÷ 48 = 37.5
