Change |
- ? |
+ ? |
After |
1 u |
1 u + 15 |
Total number of stickers
= 50 + 25
= 75
In the end
Total number of stickers = 1 u + 1 u + 15 = 2 u + 15
The total number of stickers at first and in the end remains unchanged.
2 u + 15 = 75
2 u = 75 - 15 = 60
1 u = 60 ÷ 2 = 30
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
= 50 - 30
= 20
Answer(s): 20
