Change |
- ? |
+ ? |
After |
1 u |
1 u + 50 |
Total number of stickers
= 80 + 50
= 130
In the end
Total number of stickers = 1 u + 1 u + 50 = 2 u + 50
The total number of stickers at first and in the end remains unchanged.
2 u + 50 = 130
2 u = 130 - 50 = 80
1 u = 80 ÷ 2 = 40
Number of stickers that are transferred from Box V to Box W
= Number of stickers in Box V at first - Number of stickers in Box V in the end
= 80 - 40
= 40
Answer(s): 40
