There are 65 stickers in Container D and 20 stickers in Container E.
Some stickers are transferred from Container D to Container E.
Container E has 5 more stickers than Container D.
How many stickers are transferred from Container D to Container E?
|
Container D |
Container E |
Before |
65 |
20 |
Change |
- ? |
+ ? |
After |
1 u |
1 u + 5 |
Total number of stickers
= 65 + 20
= 85
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 = 85
2 u = 85 - 5 = 80
1 u = 80 ÷ 2 = 40
Number of stickers that are transferred from Container D to Container E
= Number of stickers in Container D at first - Number of stickers in Container D in the end
= 65 - 40
= 25
Answer(s): 25
