Hazel had an equal number of passion fruits and kiwis at first. She sold one-quarter of the kiwis and bought another 10 passion fruits. In the end, she had thrice as many passion fruits as kiwis. Find the number of kiwis she had at first.

Passion Fruits |
Kiwis |
| Before |
9 u - 10 |
4 u |
| Change |
+ 10 |
- 1 u |
| After |
9 u |
3 u |
The number of passion fruits and kiwis at first is the same.
9 u - 10 = 4 u
9 u - 4 u = 10
5 u = 10
1 u = 10 ÷ 5 = 2
Number of kiwis that Hazel had at first
= 4 u
= 4 x 2
= 8
Answer(s): 8
