The bar graph shows the number of books Primary 2 students read over a week.
- Class 2 _____ and 2 _____ read 260 books in total. Give your answers in letters. (Eg A, B)
- For every 6 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 = 200
Number of books that students in Class 2C read = 60
Number of books that students in Class 2B and 2C read
= 200 + 60
= 260
(b)
Number of books that students in Class 2A read more than students read in Class 2C
= 180 - 60
= 120
Number of gifts that students in Class 2A exchanged more than students in Class 2C
= 120 ÷ 6
= 20
