How many stickers are transferred from Box V to Box W?

- ? |
+ ? |
After |
1 u + 15 |
1 u |
Total number of stickers
= 65 + 20
= 85
Total number of stickers in the end = 1 u + 15 + 1 u = 2 u + 15
The total number of stickers at first and in the end remains unchanged.
2 u + 15 = 85
2 u = 85 - 15 = 70
1 u = 70 ÷ 2 = 35
Number of stickers that are transferred from Box V to Box W
= Number of stickers in Box W in the end - Number of stickers in Box W at first
= 35 - 20
= 15
Answer(s): 15
