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 71 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 = 20
Number of pupils who borrowed 1 book each = 14
Number of pupils who borrowed 2 books each = 29
Difference between the number of pupils who borrowed only 2 books each and pupils who did not borrow any book
= 29 - 20
= 9
(b)
Number of pupils who borrowed 1 book each
= 71 - 14 - 29
= 28
Answer(s): (a) 9; (b) 28
