Some stickers are transferred from Box T to Box U.
Box T has 5 more stickers than Box U.
How many stickers are transferred from Box T to Box U?

Box T |
Box U |
Before |

60 |
Change |
- ? |
+ ? |
After |
1 u + 5 |
1 u |
Total number of stickers
= 95 + 60
= 155
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 = 155
2 u = 155 - 5 = 150
1 u = 150 ÷ 2 = 75
Number of stickers that are transferred from Box T to Box U
= Number of stickers in Box U in the end - Number of stickers in Box U at first
= 75 - 60
= 15
Answer(s): 15
