There are 75 stickers in Container E and 45 stickers in Container F.
Some stickers are transferred from Container E to Container F.
Container E has 10 more stickers than Container F.
How many stickers are transferred from Container E to Container F?

- ? |
+ ? |
After |
1 u + 10 |
1 u |
Total number of stickers
= 75 + 45
= 120
Total number of stickers in the end = 1 u + 10 + 1 u = 2 u + 10
The total number of stickers at first and in the end remains unchanged.
2 u + 10 = 120
2 u = 120 - 10 = 110
1 u = 110 ÷ 2 = 55
Number of stickers that are transferred from Container E to Container F
= Number of stickers in Container F in the end - Number of stickers in Container F at first
= 55 - 45
= 10
Answer(s): 10
