There are 25 stickers in Container X and 20 stickers in Container Y.
Some stickers are transferred from Container X to Container Y.
Container Y has 5 more stickers than Container X.
How many stickers are transferred from Container X to Container Y?
|
Container X |
Container Y |
Before |
25 |
20 |
Change |
- ? |
+ ? |
After |
1 u |
1 u + 5 |
Total number of stickers
= 25 + 20
= 45
In the end
Total number of stickers = 1 u + 1 u + 5 = 2 u + 5
The total number of stickers at first and in the end remains unchanged.
2 u + 5 = 45
2 u = 45 - 5 = 40
1 u = 40 ÷ 2 = 20
Number of stickers that are transferred from Container X to Container Y
= Number of stickers in Container X at first - Number of stickers in Container X in the end
= 25 - 20
= 5
Answer(s): 5
