The bar graph shows the number of pupils who borrowed books in Patience 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 51 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 = 11
Number of pupils who borrowed 1 book each = 26
Number of pupils who borrowed 2 books each = 24
Difference between the number of pupils who borrowed only 1 book each and pupils who did not borrow any book
= 26 - 11
= 15
(b)
Number of pupils who borrowed 3 books each
= 51 - 24
= 27
Answer(s): (a) 15; (b) 27
