Box L |
Box M |
Before |
60 |
55 |
Change |
- ? |
+ ? |
After |
1 u |
1 u + 5 |
Total number of stickers
= 60 + 55
= 115
In the end
Total number of stickers = 1 u + 1 u + 5 = 2 u + 5
The total number of stickers at first and in the end remains unchanged.
2 u + 5 = 115
2 u = 115 - 5 = 110
1 u = 110 ÷ 2 = 55
Number of stickers that are transferred from Box L to Box M
= Number of stickers in Box L at first - Number of stickers in Box L in the end
= 60 - 55
= 5
Answer(s): 5
