There are 95 stickers in Container D and 60 stickers in Container E.
Some stickers are transferred from Container D to Container E.
Container E has 15 more stickers than Container D.
How many stickers are transferred from Container D to Container E?

	Container D	Container E
Before	95	60
Change	- ?	+ ?
After	1 u	1 u + 15

Total number of stickers
= 95 + 60
= 155

In the end
Total number of stickers = 1 u + 1 u + 15 = 2 u + 15

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

2 u + 15 = 155
2 u = 155 - 15 = 140

1 u = 140 ÷ 2 = 70

Number of stickers that are transferred from Container D to Container E
= Number of stickers in Container D at first - Number of stickers in Container D in the end
= 95 - 70
= 25

Answer(s): 25
