- ? |
+ ? |
After |
1 u |
1 u + 50 |
Total number of stickers
= 100 + 100
= 200
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 = 200
2 u = 200 - 50 = 150
1 u = 150 ÷ 2 = 75
Number of stickers that are transferred from Box H to Box J
= Number of stickers in Box H at first - Number of stickers in Box H in the end
= 100 - 75
= 25
Answer(s): 25
