The bar graph shows the number of students who borrowed books in Patience School in a week.
- What was the difference between the number of students who borrowed only 1 book each and the number of students who did not borrow any book?
- There were 33 students who borrowed at least 2 books. How many of these students borrowed 3 books?
(a)
Number of students who did not borrow any book = 10
Number of students who borrowed 1 book each = 28
Number of students who borrowed 2 books each = 21
Difference between the number of students who borrowed only 1 book each and students who did not borrow any book
= 28 - 10
= 18
(b)
Number of students who borrowed 3 books each
= 33 - 21
= 12
Answer(s): (a) 18; (b) 12
