There are 100 stickers in Container N and 70 stickers in Container P.
Some stickers are transferred from Container N to Container P.
Container P has 60 more stickers than Container N.
How many stickers are transferred from Container N to Container P?

	Container N	Container P
Before	100	70
Change	- ?	+ ?
After	1 u	1 u + 60

Total number of stickers
= 100 + 70
= 170

In the end
Total number of stickers = 1 u + 1 u + 60 = 2 u + 60

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

2 u + 60 = 170
2 u = 170 - 60 = 110

1 u = 110 ÷ 2 = 55

Number of stickers that are transferred from Container N to Container P
= Number of stickers in Container N at first - Number of stickers in Container N in the end
= 100 - 55
= 45

Answer(s): 45
