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

- ? |
+ ? |
After |
1 u + 5 |
1 u |
Total number of stickers
= 80 + 35
= 115
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 = 115
2 u = 115 - 5 = 110
1 u = 110 ÷ 2 = 55
Number of stickers that are transferred from Box U to Box V
= Number of stickers in Box V in the end - Number of stickers in Box V at first
= 55 - 35
= 20
Answer(s): 20
