25 |
Change |
- ? |
+ ? |
After |
1 u |
1 u + 10 |
Total number of stickers
= 65 + 25
= 90
In the end
Total number of stickers = 1 u + 1 u + 10 = 2 u + 10
The total number of stickers at first and in the end remains unchanged.
2 u + 10 = 90
2 u = 90 - 10 = 80
1 u = 80 ÷ 2 = 40
Number of stickers that are transferred from Box U to Box V
= Number of stickers in Box U at first - Number of stickers in Box U in the end
= 65 - 40
= 25
Answer(s): 25
