(a)
Number of books that students in Class 3B read = 300
Number of books that students in Class 3C read = 110
Number of books that students in Class 3B and 3C read
= 300 + 110
= 410
(b)

= 250 - 110
= 140
Number of gifts that students in Class 3A exchanged more than students in Class 3C
= 140 ÷ 4
= 35
