- ? |
+ ? |
After |
1 u |
1 u + 45 |
Total number of stickers
= 80 + 65
= 145
In the end
Total number of stickers = 1 u + 1 u + 45 = 2 u + 45
The total number of stickers at first and in the end remains unchanged.
2 u + 45 = 145
2 u = 145 - 45 = 100
1 u = 100 ÷ 2 = 50
Number of stickers that are transferred from Box F to Box G
= Number of stickers in Box F at first - Number of stickers in Box F in the end
= 80 - 50
= 30
Answer(s): 30
