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 50 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 = 10
Number of pupils who borrowed 1 book each = 11
Number of pupils who borrowed 2 books each = 23
Difference between the number of pupils who borrowed only 2 books each and pupils who did not borrow any book
= 23 - 10
= 13
(b)
Number of pupils who borrowed 1 book each
= 50 - 11 - 23
= 16
Answer(s): (a) 13; (b) 16
