Gwen had an equal number of kiwis and passion fruits at first. She sold half of the passion fruits and bought another 20 kiwis. In the end, she had six times as many kiwis as passion fruits. Find the number of passion fruits she had at first.

Kiwis |
Passion Fruits |
| Before |
6 u - 20 |
2 u |
| Change |
+ 20 |
- 1 u |
| After |
6 u |
1 u |
The number of kiwis and passion fruits at first is the same.
6 u - 20 = 2 u
6 u - 2 u = 20
4 u = 20
1 u = 20 ÷ 4 = 5
Number of passion fruits that Gwen had at first
= 2 u
= 2 x 5
= 10
