<PRE><B>Question 641858</B>
If the average (arithmetic mean) of eight numbers is 20 and the average of five of these numbers is 14, what is the average of the other three numbers?
----------------
Total points for the eight numbers: 8*20 = 160 
---
Total points for the five numbers: 5*14 = 70 points
---
Average for the other three numbers: (160-70)/3 = 30
----------------------------
