There are 60 stickers in Container D and 25 stickers in Container E.
Some stickers are transferred from Container D to Container E.
Container D has 25 more stickers than Container E.
How many stickers are transferred from Container D to Container E?

	Container D	Container E
Before	60	25
Change	- ?	+ ?
After	1 u + 25	1 u

Total number of stickers
= 60 + 25
= 85

Total number of stickers in the end = 1 u + 25 + 1 u = 2 u + 25

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

2 u + 25 = 85
2 u = 85 - 25 = 60

1 u = 60 ÷ 2 = 30

Number of stickers that are transferred from Container D to Container E
= Number of stickers in Container E in the end - Number of stickers in Container E at first
= 30 - 25
= 5

Answer(s): 5
