75 |
Change |
- ? |
+ ? |
After |
1 u |
1 u + 60 |
Total number of stickers
= 85 + 75
= 160
In the end
Total number of stickers = 1 u + 1 u + 60 = 2 u + 60
The total number of stickers at first and in the end remains unchanged.
2 u + 60 = 160
2 u = 160 - 60 = 100
1 u = 100 ÷ 2 = 50
Number of stickers that are transferred from Box K to Box L
= Number of stickers in Box K at first - Number of stickers in Box K in the end
= 85 - 50
= 35
Answer(s): 35
