The bar graph shows the number of books Primary 2 students read over a week.
- Class 2 _____ and 2 _____ read 320 books in total. Give your answers in letters. (Eg A, B)
- For every 4 books read by the students, they can exchange for 1 gift. How many more gifts did Class 2A exchange than Class 2C?
(a)
Number of books that students in Class 2B read = 260
Number of books that students in Class 2C read = 60
Number of books that students in Class 2B and 2C read
= 260 + 60
= 320
(b)
Number of books that students in Class 2A read more than students read in Class 2C
= 220 - 60
= 160
Number of gifts that students in Class 2A exchanged more than students in Class 2C
= 160 ÷ 4
= 40
