Pamela had an equal number of persimmons and passion fruits at first. She sold half of the passion fruits and bought another 30 persimmons. In the end, she had four times as many persimmons as passion fruits. Find the number of passion fruits she had at first.

Persimmons |
Passion Fruits |
| Before |
4 u - 30 |
2 u |
| Change |
+ 30 |
- 1 u |
| After |
4 u |
1 u |
The number of persimmons and passion fruits at first is the same.
4 u - 30 = 2 u
4 u - 2 u = 30
2 u = 30
1 u = 30 ÷ 2 = 15
Number of passion fruits that Pamela had at first
= 2 u
= 2 x 15
= 30
