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

Pomegranates |
Passion Fruits |
| Before |
4 u - 30 |
2 u |
| Change |
+ 30 |
- 1 u |
| After |
4 u |
1 u |
The number of pomegranates 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 Usha had at first
= 2 u
= 2 x 15
= 30
