Read the questions carefully.
Find the average of the following.
Example:
If the average of four tests of a student is 75 and wants to raise to 80 what must he score in the fifth test?
Average of four tests = 75
Total /4 = 75
Hence total = 75 x 4 = 300
To make the average 80
Total/5 = 80
Hence total = 400
The number he must score in fifth test = 400- 300 Answer: 100
