There are 35 stickers in Container P and 10 stickers in Container Q.
Some stickers are transferred from Container P to Container Q.
Container Q has 5 more stickers than Container P.
How many stickers are transferred from Container P to Container Q?
|
Container P |
Container Q |
Before |
35 |
10 |
Change |
- ? |
+ ? |
After |
1 u |
1 u + 5 |
Total number of stickers
= 35 + 10
= 45
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 = 45
2 u = 45 - 5 = 40
1 u = 40 ÷ 2 = 20
Number of stickers that are transferred from Container P to Container Q
= Number of stickers in Container P at first - Number of stickers in Container P in the end
= 35 - 20
= 15
Answer(s): 15
