There are 100 stickers in Container E and 65 stickers in Container F.
Some stickers are transferred from Container E to Container F.
Container E has 25 more stickers than Container F.
How many stickers are transferred from Container E to Container F?

	Container E	Container F
Before	100	65
Change	- ?	+ ?
After	1 u + 25	1 u

Total number of stickers
= 100 + 65
= 165

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 = 165
2 u = 165 - 25 = 140

1 u = 140 ÷ 2 = 70

Number of stickers that are transferred from Container E to Container F
= Number of stickers in Container F in the end - Number of stickers in Container F at first
= 70 - 65
= 5

Answer(s): 5
