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 2 books each and the number of pupils who did not borrow any book?
- There were 58 pupils who borrowed at least 1 book. 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 = 16
Difference between the number of pupils who borrowed only 2 books each and pupils who did not borrow any book
= 16 - 12
= 4
(b)
Number of pupils who borrowed 1 book each
= 58 - 15 - 16
= 27
Answer(s): (a) 4; (b) 27
