(a)
At first
Number of stickers that Adam has = 1 u = 500
Number of stickers that Charlie has = 5 u
Total number of stickers
= 1 u + 5 u
= 6 u
To have equal number of stickers,
the stickers must be equally divided into 2 groups.
In the end
Number of stickers that each boy has
= 6 u ÷ 2
= 3 u
Number of stickers that Charlie must give to Adam
= 5 u - 3 u
= 2 u
= 2 x 500
= 1000
(b)
Number of stickers that each boy will have in the end
= 3 u
= 3 x 500
= 1500
Answer(s): (a) 1000; (b) 1500
