How many stickers are transferred from Container Q to Container R?

Container Q |
Container R |
Before |
80 |
55 |
Change |
- ? |
+ ? |
After |
1 u |
1 u + 35 |
Total number of stickers
= 80 + 55
= 135
In the end
Total number of stickers = 1 u + 1 u + 35 = 2 u + 35
The total number of stickers at first and in the end remains unchanged.
2 u + 35 = 135
2 u = 135 - 35 = 100
1 u = 100 ÷ 2 = 50
Number of stickers that are transferred from Container Q to Container R
= Number of stickers in Container Q at first - Number of stickers in Container Q in the end
= 80 - 50
= 30
Answer(s): 30
