The bar graph shows the number of pupils who borrowed books in Joy School in a week.
- What was the difference between the number of pupils who borrowed only 1 book each and the number of pupils who did not borrow any book?
- There were 24 pupils who borrowed at least 2 books. How many of these pupils borrowed 3 books?
(a)
Number of pupils who did not borrow any book = 12
Number of pupils who borrowed 1 book each = 15
Number of pupils who borrowed 2 books each = 10
Difference between the number of pupils who borrowed only 1 book each and pupils who did not borrow any book
= 15 - 12
= 3
(b)
Number of pupils who borrowed 3 books each
= 24 - 10
= 14
Answer(s): (a) 3; (b) 14
