Nick and Ahmad had 87 staplers. After Nick gave 17 staplers to Ahmad. Ahmad, in return, gave half of his staplers to Nick. In the end, Nick had twice as many staplers as Ahmad. How many staplers did Nick have at first?

Nick |
Ahmad |
Total |
| Before |
1 u + 17 |
2 u - 17 |
87 |
| Change 1 |
- 17 |
+ 17 |
|
| After 1 |
1 u |
2 u |
|
| Change 2 |
+ 1 u |
- 1 u |
|
| After 2 |
2 u |
1 u |
87 |
Total number of staplers that Nick and Ahmad had at first and in the end remains unchanged.
Total number of staplers
= 2 u + 1 u
= 3 u
1 u = 87 ÷ 3 = 29
Number of staplers that Nick had at first
= 1 u + 17
= 29 + 17
= 46
Answer(s): 46
