(a)
20% =
20100 =
15 Number of stickers that Charlie has = 1 u
Number of stickers that Bryan has = 5 u
Total number of stickers
= 1 u + 5 u
= 6 u
6 u = 210
1 u = 210 ÷ 6 = 35
Number of stickers that each boy will have in the end
= 6 u ÷ 2
= 3 u
Number of stickers that Bryan must give to Charlie
= 5 u - 3 u
= 2 u
= 2 x 35
= 70
(b)
Number of stickers that each of them have in the end
= 210 ÷ 2
= 105
Answer(s): (a) 70; (b) 105
