Question 521165: The average of four numbers is 18. If one of the four numbers, 25, is taken away, what is the average of the remaining three numbers? Answer by solver91311(24713) (Show Source):
If the average of 4 numbers is 18, then the sum of the 4 numbers has to be 4 times 18. If you subtract 25 from this sum, you will have the sum of the remaining 3 numbers that you can then divide by 3 to find the average of the 3.
