Before |

65 |
Change |
- ? |
+ ? |
After |
1 u + 15 |
1 u |
Total number of stickers
= 100 + 65
= 165
Total number of stickers in the end = 1 u + 15 + 1 u = 2 u + 15
The total number of stickers at first and in the end remains unchanged.
2 u + 15 = 165
2 u = 165 - 15 = 150
1 u = 150 ÷ 2 = 75
Number of stickers that are transferred from Container Q to Container R
= Number of stickers in Container R in the end - Number of stickers in Container R at first
= 75 - 65
= 10
Answer(s): 10
