The bar graph shows the number of pupils who borrowed books in Faithfulness 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 73 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 = 30
Number of pupils who borrowed 2 books each = 24
Difference between the number of pupils who borrowed only 2 books each and pupils who did not borrow any book
= 24 - 12
= 12
(b)
Number of pupils who borrowed 1 book each
= 73 - 30 - 24
= 19
Answer(s): (a) 12; (b) 19
