The bar graph shows the number of books Primary 2 pupils read over a week.
- Class 2 _____ and 2 _____ read 370 books in total. Give your answers in letters. (Eg A, B)
- For every 2 books read by the pupils, they can exchange for 1 gift. How many more gifts did Class 2A exchange than Class 2C?
(a)
Number of books that pupils in Class 2B read = 270
Number of books that pupils in Class 2C read = 100
Number of books that pupils in Class 2B and 2C read
= 270 + 100
= 370
(b)
Number of books that pupils in Class 2A read more than pupils read in Class 2C
= 200 - 100
= 100
Number of gifts that pupils in Class 2A exchanged more than pupils in Class 2C
= 100 ÷ 2
= 50
Answer(s): (a) B, C; (b) 50
