An average of 90 on four papers means that the total of the four papers must be:

4*90 = 360

If you know the scores of three of the four papers, can you find the minimum of the fourth?

The lowest score the student could make on the last paper and still get an A is 97%. So all the test scores would be: 92, 83, 88, and 97.
