Arithmetic means of 25 values is 10, what is the sum of values?
- 2.5
- 25
- 125
- 250
Explanation
The arithmetic mean (average) of 25 values is 10, so we can set up the equation:
Sum of values / 25 = 10
Multiply both sides by 25:
Sum of values = 25 × 10
Sum of values = 250
So, the correct answer is: 250
