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

25 |
Change |
- ? |
+ ? |
After |
1 u + 20 |
1 u |
Total number of stickers
= 65 + 25
= 90
Total number of stickers in the end = 1 u + 20 + 1 u = 2 u + 20
The total number of stickers at first and in the end remains unchanged.
2 u + 20 = 90
2 u = 90 - 20 = 70
1 u = 70 ÷ 2 = 35
Number of stickers that are transferred from Container P to Container Q
= Number of stickers in Container Q in the end - Number of stickers in Container Q at first
= 35 - 25
= 10
Answer(s): 10
