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

Container Q |
Container R |
Before |
95 |
50 |
Change |
- ? |
+ ? |
After |
1 u + 5 |
1 u |
Total number of stickers
= 95 + 50
= 145
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 = 145
2 u = 145 - 5 = 140
1 u = 140 ÷ 2 = 70
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
= 70 - 50
= 20
Answer(s): 20
