Anna had an equal number of apples and mangosteens at first. She sold one-quarter of the mangosteens and bought another 32 apples. In the end, she had twice as many apples as mangosteens. Find the number of mangosteens she had at first.

Mangosteens |
Apples |
| Before |
4 u |
6 u - 32 |
| Change |
- 1 u |
+ 32 |
| After |
3 u |
6 u |
The number of apples and mangosteens at first is the same.
6 u - 32 = 4 u
6 u - 4 u = 32
2 u = 32
1 u = 32 ÷ 2 = 16
Number of mangosteens that she had at first
= 4 u
= 4 x 16
= 64
Answer(s): 64
