(a)
Number of books that students in Class 6C read = 100
Number of books that students in Class 6D read = 160
Number of books that students in Class 6C and 6D read
= 100 + 160
= 260
(b)
Number of books that students in Class 6B read more than students read in Class 6D
= 300 - 160
= 140
Number of gifts that students in Class 6B exchanged more than students in Class 6D
= 140 ÷ 2
= 70
