Answer:

The total numbers of problems is 95

Explanation:

Let the total numbers of problems be x

So, Total no. of problems x is 100%

Correct no. of problems on test = 76

We are given that he received a grade of 80%.

So, Correct no. of problems is 80 i.e. 80%

So,
$(x)/(76)=(100)/(80)\\x=(100)/(80) * 76\\x=95$

Hence the total numbers of problems is 95
