(a)
Total number of stickers received = 4 u
4 u = 100
1 u = 100 ÷ 4 = 25
Total number of stickers that David, Tom and Ian received
= 100 - 25
= 75
Total number of stickers that David, Tom and Ian received
= 1 p + 4 p
= 5 p
1 p = 75 ÷ 5 = 15
Number of stickers that David received
= 1 p
= 15
(b)
Number of more stickers that Charlie received more than Tom
= 1 u - 1 p
= 25 - 15
= 10
Answer(s): (a) 15; (b) 10
