There are 65,438+000 books in the library. The borrower needs to sign the book. It is known that 33 and 4 of these 65,438+000 books are signed by A, B and C respectively.
A+B+C-(A and B)-(B and C)-(A and C)+(A, B and C)

34+47+52-30-25-36+ (A, B and C)

=42+ (Party A, Party B and Party C borrow books)

A、B、30 A、C、25 B、C、36

Then A, B and C can borrow 25 books at most.

So at least one person has borrowed books, at most:

42+25=67 copies

So there are no books borrowed, at least:

100-67=33 copies
