Some stickers are transferred from Container A to Container B.
Container A has 5 more stickers than Container B.
How many stickers are transferred from Container A to Container B?

Container A |
Container B |
Before |
80 |
15 |
Change |
- ? |
+ ? |
After |
1 u + 5 |
1 u |
Total number of stickers
= 80 + 15
= 95
Total number of stickers in the end = 1 u + 5 + 1 u = 2 u + 5
The total number of stickers at first and in the end remains unchanged.
2 u + 5 = 95
2 u = 95 - 5 = 90
1 u = 90 ÷ 2 = 45
Number of stickers that are transferred from Container A to Container B
= Number of stickers in Container B in the end - Number of stickers in Container B at first
= 45 - 15
= 30
Answer(s): 30
