The bar graph shows the number of books Primary 6 pupils read over a week.
- Class 6 _____ and 6 _____ read 220 books in total. Give your answers in letters. (Eg A, B)
- For every 2 books read by the pupils, they can exchange for 1 gift. How many more gifts did Class 6B exchange than Class 6D?
(a)
Number of books that pupils in Class 6C read = 60
Number of books that pupils in Class 6D read = 160
Number of books that pupils in Class 6C and 6D read
= 60 + 160
= 220
(b)
Number of books that pupils in Class 6B read more than pupils read in Class 6D
= 250 - 160
= 90
Number of gifts that pupils in Class 6B exchanged more than pupils in Class 6D
= 90 ÷ 2
= 45
