Yoko had an equal number of passion fruits and peaches at first. She sold one-third of the peaches and bought another 20 passion fruits. In the end, she had four times as many passion fruits as peaches. Find the number of peaches she had at first.

Passion Fruits |
Peaches |
| Before |
8 u - 20 |
3 u |
| Change |
+ 20 |
- 1 u |
| After |
8 u |
2 u |
The number of passion fruits and peaches at first is the same.
8 u - 20 = 3 u
8 u - 3 u = 20
5 u = 20
1 u = 20 ÷ 5 = 4
Number of peaches that Yoko had at first
= 3 u
= 3 x 4
= 12
Answer(s): 12
