Before |
95 |
90 |
Change |
- ? |
+ ? |
After |
1 u |
1 u + 85 |
Total number of stickers
= 95 + 90
= 185
In the end
Total number of stickers = 1 u + 1 u + 85 = 2 u + 85
The total number of stickers at first and in the end remains unchanged.
2 u + 85 = 185
2 u = 185 - 85 = 100
1 u = 100 ÷ 2 = 50
Number of stickers that are transferred from Box Y to Box Z
= Number of stickers in Box Y at first - Number of stickers in Box Y in the end
= 95 - 50
= 45
Answer(s): 45
