Asked by Karen

The average of five number is 56. Four of the numbers are the same. The average of one of the four number and the fifth number is 80. What is the fifth number.

56*5=280
80*2=160
280-160=120
5/120=24

Is 24 correct?
Answered by bobpursley
No. Shouldn't the 120 be divided by three?

40,40,40,40,120 it seems to me.

That makes sense I need to leave out the 1st and the fifth number and use just the three numbers that are not calculated. Bob you are a life saver thank you.
