Wesley and Paul had 78 markers. After Wesley gave 13 markers to Paul. Paul, in return, gave half of his markers to Wesley. In the end, Wesley had twice as many markers as Paul. How many markers did Wesley have at first?

Total |
| Before |
1 u + 13 |
2 u - 13 |
78 |
| Change 1 |
- 13 |
+ 13 |
|
| After 1 |
1 u |
2 u |
|
| Change 2 |
+ 1 u |
- 1 u |
|
| After 2 |
2 u |
1 u |
78 |
Total number of markers that Wesley and Paul had at first and in the end remains unchanged.
Total number of markers
= 2 u + 1 u
= 3 u
1 u = 78 ÷ 3 = 26
Number of markers that Wesley had at first
= 1 u + 13
= 26 + 13
= 39
Answer(s): 39
