Victoria had an equal number of mangosteens and pomegranates at first. She sold one-third of the pomegranates and bought another 30 mangosteens. In the end, she had four times as many mangosteens as pomegranates. Find the number of pomegranates she had at first.

Mangosteens |
Pomegranates |
| Before |
8 u - 30 |
3 u |
| Change |
+ 30 |
- 1 u |
| After |
8 u |
2 u |
The number of mangosteens and pomegranates at first is the same.
8 u - 30 = 3 u
8 u - 3 u = 30
5 u = 30
1 u = 30 ÷ 5 = 6
Number of pomegranates that Victoria had at first
= 3 u
= 3 x 6
= 18
Answer(s): 18
