There are 85 stickers in Container J and 50 stickers in Container K.
Some stickers are transferred from Container J to Container K.
Container J has 5 more stickers than Container K.
How many stickers are transferred from Container J to Container K?

	Container J	Container K
Before	85	50
Change	- ?	+ ?
After	1 u + 5	1 u

Total number of stickers
= 85 + 50
= 135

Total number of stickers in the end = 1 u + 5 + 1 u = 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 J to Container K
= Number of stickers in Container K in the end - Number of stickers in Container K at first
= 65 - 50
= 15

Answer(s): 15
