Paul and Ryan had 51 staplers. After Paul gave 24 staplers to Ryan. Ryan, in return, gave half of his staplers to Paul. In the end, Paul had twice as many staplers as Ryan. How many staplers did Paul have at first?

Total |
| Before |
1 u + 24 |
2 u - 24 |
51 |
| Change 1 |
- 24 |
+ 24 |
|
| After 1 |
1 u |
2 u |
|
| Change 2 |
+ 1 u |
- 1 u |
|
| After 2 |
2 u |
1 u |
51 |
Total number of staplers that Paul and Ryan had at first and in the end remains unchanged.
Total number of staplers
= 2 u + 1 u
= 3 u
1 u = 51 ÷ 3 = 17
Number of staplers that Paul had at first
= 1 u + 24
= 17 + 24
= 41
Answer(s): 41
