There are 15 stickers in Container V and 15 stickers in Container W.
Some stickers are transferred from Container V to Container W.
Container W has 10 more stickers than Container V.
How many stickers are transferred from Container V to Container W?

Container V |
Container W |
Before |
15 |
15 |
Change |
- ? |
+ ? |
After |
1 u |
1 u + 10 |
Total number of stickers
= 15 + 15
= 30
In the end
Total number of stickers = 1 u + 1 u + 10 = 2 u + 10
The total number of stickers at first and in the end remains unchanged.
2 u + 10 = 30
2 u = 30 - 10 = 20
1 u = 20 ÷ 2 = 10
Number of stickers that are transferred from Container V to Container W
= Number of stickers in Container V at first - Number of stickers in Container V in the end
= 15 - 10
= 5
Answer(s): 5
