If a person makes a 72 on their quiz that is ten percent and makes a 72 on their second quiz that is ten percent and makes a 77 on their test that is forty percent what is their average?
---------------
10 + 10 + 40 = 60%
What is the other 40% ?

It's a weighted average problem:
72%2A.1=+7.2
72%2A.1=+7.2
77%2A.4=+30.8
---------------
Average: 45.2+
Note: One test is 10%, second is also 10% and third is 40%, all together 60%.
Either you're missing one grade that's worth 40% or this is a real life example and you have one test to go that will be worth 40%.
Anyway, you're 40% short.
