There are five scoring situations.

Think of it as five drawers.

At least 5 students have the same score, so at least:

5×4+ 1=2 1 person

If at least five students get the same score in each question, it will be the same as the landlord.

It should be 37 people

In any case, the answers in the book are unreasonable.

Believe in yourself and the truth!
