There are 95 stickers in Container E and 40 stickers in Container F.
Some stickers are transferred from Container E to Container F.
Container F has 5 more stickers than Container E.
How many stickers are transferred from Container E to Container F?

	Container E	Container F
Before	95	40
Change	- ?	+ ?
After	1 u	1 u + 5

Total number of stickers
= 95 + 40
= 135

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

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

2 u + 5 = 135
2 u = 135 - 5 = 130

1 u = 130 ÷ 2 = 65

Number of stickers that are transferred from Container E to Container F
= Number of stickers in Container E at first - Number of stickers in Container E in the end
= 95 - 65
= 30

Answer(s): 30
