(a)
Total number of stickers received = 5 u
5 u = 135
1 u = 135 ÷ 5 = 27
Total number of stickers that Ken, David and Harry received
= 135 - 27
= 108
Total number of stickers that Ken, David and Harry received
= 1 p + 5 p
= 6 p
1 p = 108 ÷ 6 = 18
Number of stickers that Ken received
= 1 p
= 18
(b)
Number of more stickers that Justin received more than David
= 1 u - 1 p
= 27 - 18
= 9
Answer(s): (a) 18; (b) 9
