The bar graph shows the number of books Primary 2 students read over a week.
- Class 2 _____ and 2 _____ read 300 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 2B exchange than Class 2C?
(a)
Number of books that students in Class 2A read = 220
Number of books that students in Class 2C read = 80
Number of books that students in Class 2A and 2C read
= 220 + 80
= 300
(b)
Number of books that students in Class 2B read more than students read in Class 2C
= 290 - 80
= 210
Number of gifts that students in Class 2B exchanged more than students in Class 2C
= 210 ÷ 2
= 105
