If the mean of four numbers is 95, what is their total sum?

Explanation:
The mean tells you the total sum of all numbers when you know how many numbers there are. To get the sum, multiply the mean by the count. Here there are four numbers and the average is 95, so the total sum is 95 × 4 = 380. A sum of 360 would give an average of 90, 400 would give 100, and 420 would give 105, which don’t match the given mean.
