- There were 63 students who borrowed at least 1 book. How many of these students borrowed 3 books?
(a)
Number of students who did not borrow any book = 17
Number of students who borrowed 1 book each = 16

Difference between the number of students who borrowed only 2 books each and students who did not borrow any book
= 29 - 17
= 12
(b)
Number of students who borrowed 1 book each
= 63 - 16 - 29
= 18
Answer(s): (a) 12; (b) 18
