There are 85 stickers in Container W and 30 stickers in Container X.
Some stickers are transferred from Container W to Container X.
Container W has 5 more stickers than Container X.
How many stickers are transferred from Container W to Container X?

	Container W	Container X
Before	85	30
Change	- ?	+ ?
After	1 u + 5	1 u

Total number of stickers
= 85 + 30
= 115

Total number of stickers in the end = 1 u + 5 + 1 u = 2 u + 5

The total number of stickers at first and in the end remains unchanged.

2 u + 5 = 115
2 u = 115 - 5 = 110

1 u = 110 ÷ 2 = 55

Number of stickers that are transferred from Container W to Container X
= Number of stickers in Container X in the end - Number of stickers in Container X at first
= 55 - 30
= 25

Answer(s): 25
