The bar graph shows the number of students who borrowed books in Gentleness 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 68 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 = 21
Number of students who borrowed 2 books each = 27
Difference between the number of students who borrowed only 2 books each and students who did not borrow any book
= 27 - 10
= 17
(b)
Number of students who borrowed 1 book each
= 68 - 21 - 27
= 20
Answer(s): (a) 17; (b) 20
