Emma had an equal number of plums and guavas at first. She sold half of the guavas and bought another 32 plums. In the end, she had four times as many plums as guavas. Find the number of guavas she had at first.

Guavas |
Plums |
| Before |
2 u |
4 u - 32 |
| Change |
- 1 u |
+ 32 |
| After |
1 u |
4 u |
The number of plums and guavas at first is the same.
4 u - 32 = 2 u
4 u - 2 u = 32
2 u = 32
1 u = 32 ÷ 2 = 16
Number of guavas that she had at first
= 2 u
= 2 x 16
= 32
Answer(s): 32
