Let s be the score of the 3rd game
s+10 was 1st game
s-5 was 2nd game

s+10 + s-5 + s = 275
3s + 5 = 275
3s = 270
s = 90
n
So, the 3 games were 100 85 90

Don't know why the "highest number" question was asked. The answer is exact.

If they had said "at least 275" or "at most 275" then there would have been an inequality.
