The bar graph shows the number of students who borrowed books in Joy School in a week.
- What was the difference between the number of students who borrowed 2 books each and the number of students who did not borrow any book?
- There were 49 students who borrowed at least 1 book. How many of these students borrowed 3 books?
(a)
Number of students who did not borrow any book = 12
Number of students who borrowed 1 book each = 14
Number of students who borrowed 2 books each = 16
Difference between the number of students who borrowed only 2 books each and students who did not borrow any book
= 16 - 12
= 4
(b)
Number of students who borrowed 1 book each
= 49 - 14 - 16
= 19
Answer(s): (a) 4; (b) 19
