The bar graph shows the number of books Primary 4 students read over a week.
- Class 4 _____ and 4 _____ read 260 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 4B exchange than Class 4C?
(a)
Number of books that students in Class 4A read = 210
Number of books that students in Class 4C read = 50
Number of books that students in Class 4A and 4C read
= 210 + 50
= 260
(b)
Number of books that students in Class 4B read more than students read in Class 4C
= 270 - 50
= 220
Number of gifts that students in Class 4B exchanged more than students in Class 4C
= 220 ÷ 2
= 110
