Gao Xiao's Mathematical Interpretation
You get 100 if you are right, and deduct 8 points from 100 if you are wrong.

If you get 60 points, you lose 40 points, that is, you made five mistakes and got 15.

Only 25- 15 = 10 people answered the first question correctly.

Only 23- 15 = 8 people answered the second question correctly.

15 people did it right.

10+8+ 15 = 33 people answered at least one question correctly.

36-33 = 3 people are wrong.
