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

Container Q |
Container R |
Before |
45 |
20 |
Change |
- ? |
+ ? |
After |
1 u + 5 |
1 u |
Total number of stickers
= 45 + 20
= 65
Total number of stickers in the end = 1 u + 5 + 1 u = 2 u + 5
The total number of stickers at first and in the end remains unchanged.
2 u + 5 = 65
2 u = 65 - 5 = 60
1 u = 60 ÷ 2 = 30
Number of stickers that are transferred from Container Q to Container R
= Number of stickers in Container R in the end - Number of stickers in Container R at first
= 30 - 20
= 10
Answer(s): 10
