The bar graph shows the number of students who borrowed books in Love 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 80 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 = 10
Number of students who borrowed 1 book each = 30
Number of students who borrowed 2 books each = 23
Difference between the number of students who borrowed only 2 books each and students who did not borrow any book
= 23 - 10
= 13
(b)
Number of students who borrowed 1 book each
= 80 - 30 - 23
= 27
Answer(s): (a) 13; (b) 27
