Hilda had an equal number of lemons and guavas at first. She sold one-quarter of the guavas and bought another 85 lemons. In the end, she had thrice as many lemons as guavas. Find the number of guavas she had at first.

Guavas |
Lemons |
| Before |
4 u |
9 u - 85 |
| Change |
- 1 u |
+ 85 |
| After |
3 u |
9 u |
The number of lemons and guavas at first is the same.
9 u - 85 = 4 u
9 u - 4 u = 85
5 u = 85
1 u = 85 ÷ 5 = 17
Number of guavas that she had at first
= 4 u
= 4 x 17
= 68
Answer(s): 68
