Change |
- ? |
+ ? |
After |
1 u |
1 u + 35 |
Total number of stickers
= 60 + 35
= 95
In the end
Total number of stickers = 1 u + 1 u + 35 = 2 u + 35
The total number of stickers at first and in the end remains unchanged.
2 u + 35 = 95
2 u = 95 - 35 = 60
1 u = 60 ÷ 2 = 30
Number of stickers that are transferred from Box Q to Box R
= Number of stickers in Box Q at first - Number of stickers in Box Q in the end
= 60 - 30
= 30
Answer(s): 30
