Change |
- ? |
+ ? |
After |
1 u |
1 u + 25 |
Total number of stickers
= 95 + 60
= 155
In the end
Total number of stickers = 1 u + 1 u + 25 = 2 u + 25
The total number of stickers at first and in the end remains unchanged.
2 u + 25 = 155
2 u = 155 - 25 = 130
1 u = 130 ÷ 2 = 65
Number of stickers that are transferred from Box J to Box K
= Number of stickers in Box J at first - Number of stickers in Box J in the end
= 95 - 65
= 30
Answer(s): 30
