How many stickers are transferred from Box W to Box X?

- ? |
+ ? |
After |
1 u + 5 |
1 u |
Total number of stickers
= 90 + 65
= 155
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 = 155
2 u = 155 - 5 = 150
1 u = 150 ÷ 2 = 75
Number of stickers that are transferred from Box W to Box X
= Number of stickers in Box X in the end - Number of stickers in Box X at first
= 75 - 65
= 10
Answer(s): 10
