Jane had an equal number of guavas and mangoes at first. She sold half of the mangoes and bought another 22 guavas. In the end, she had four times as many guavas as mangoes. Find the number of mangoes she had at first.

Guavas |
Mangoes |
| Before |
4 u - 22 |
2 u |
| Change |
+ 22 |
- 1 u |
| After |
4 u |
1 u |
The number of guavas and mangoes at first is the same.
4 u - 22 = 2 u
4 u - 2 u = 22
2 u = 22
1 u = 22 ÷ 2 = 11
Number of mangoes that Jane had at first
= 2 u
= 2 x 11
= 22
Answer(s): 22
