Some stickers are transferred from Container U to Container V.
Container V has 10 more stickers than Container U.
How many stickers are transferred from Container U to Container V?

Container U |
Container V |
Before |
85 |
55 |
Change |
- ? |
+ ? |
After |
1 u |
1 u + 10 |
Total number of stickers
= 85 + 55
= 140
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 = 140
2 u = 140 - 10 = 130
1 u = 130 ÷ 2 = 65
Number of stickers that are transferred from Container U to Container V
= Number of stickers in Container U at first - Number of stickers in Container U in the end
= 85 - 65
= 20
Answer(s): 20
