The bar graph shows the number of books Primary 6 students read over a week.
- Class 6 _____ and 6 _____ read 250 books in total. Give your answers in letters. (Eg A, B)
- For every 2 books read by the students, they can exchange for 1 gift. How many more gifts did Class 6B exchange than Class 6D?
(a)
Number of books that students in Class 6C read = 90
Number of books that students in Class 6D read = 160
Number of books that students in Class 6C and 6D read
= 90 + 160
= 250
(b)
Number of books that students in Class 6B read more than students read in Class 6D
= 230 - 160
= 70
Number of gifts that students in Class 6B exchanged more than students in Class 6D
= 70 ÷ 2
= 35
