There are 90 stickers in Container V and 30 stickers in Container W.
Some stickers are transferred from Container V to Container W.
Container V has 10 more stickers than Container W.
How many stickers are transferred from Container V to Container W?

Container V |
Container W |
Before |
90 |
30 |
Change |
- ? |
+ ? |
After |
1 u + 10 |
1 u |
Total number of stickers
= 90 + 30
= 120
Total number of stickers in the end = 1 u + 10 + 1 u = 2 u + 10
The total number of stickers at first and in the end remains unchanged.
2 u + 10 = 120
2 u = 120 - 10 = 110
1 u = 110 ÷ 2 = 55
Number of stickers that are transferred from Container V to Container W
= Number of stickers in Container W in the end - Number of stickers in Container W at first
= 55 - 30
= 25
Answer(s): 25
