There are 95 stickers in Container B and 85 stickers in Container C.
Some stickers are transferred from Container B to Container C.
Container C has 40 more stickers than Container B.
How many stickers are transferred from Container B to Container C?

	Container B	Container C
Before	95	85
Change	- ?	+ ?
After	1 u	1 u + 40

Total number of stickers
= 95 + 85
= 180

In the end
Total number of stickers = 1 u + 1 u + 40 = 2 u + 40

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

2 u + 40 = 180
2 u = 180 - 40 = 140

1 u = 140 ÷ 2 = 70

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

Answer(s): 25
