- ? |
+ ? |
After |
1 u |
1 u + 70 |
Total number of stickers
= 70 + 70
= 140
In the end
Total number of stickers = 1 u + 1 u + 70 = 2 u + 70
The total number of stickers at first and in the end remains unchanged.
2 u + 70 = 140
2 u = 140 - 70 = 70
1 u = 70 ÷ 2 = 35
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
= 70 - 35
= 35
Answer(s): 35
