There are 75 stickers in Container V and 25 stickers in Container W.
Some stickers are transferred from Container V to Container W.
Container V has 10 more stickers than Container W.
How many stickers are transferred from Container V to Container W?

	Container V	Container W
Before	75	25
Change	- ?	+ ?
After	1 u + 10	1 u

Total number of stickers
= 75 + 25
= 100

Total number of stickers in the end = 1 u + 10 + 1 u = 2 u + 10

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

2 u + 10 = 100
2 u = 100 - 10 = 90

1 u = 90 ÷ 2 = 45

Number of stickers that are transferred from Container V to Container W
= Number of stickers in Container W in the end - Number of stickers in Container W at first
= 45 - 25
= 20

Answer(s): 20
