The bar graph shows the number of books Primary 6 students read over a week.
- Class 6 _____ and 6 _____ read 290 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 6A exchange than Class 6C?
(a)
Number of books that students in Class 6B read = 240
Number of books that students in Class 6C read = 50
Number of books that students in Class 6B and 6C read
= 240 + 50
= 290
(b)
Number of books that students in Class 6A read more than students read in Class 6C
= 230 - 50
= 180
Number of gifts that students in Class 6A exchanged more than students in Class 6C
= 180 ÷ 4
= 45
