Jade had an equal number of mangosteens and pears at first. She sold half of the pears and bought another 54 mangosteens. In the end, she had five times as many mangosteens as pears. Find the number of pears she had at first.

Pears |
Mangosteens |
| Before |
2 u |
5 u - 54 |
| Change |
- 1 u |
+ 54 |
| After |
1 u |
5 u |
The number of mangosteens and pears at first is the same.
5 u - 54 = 2 u
5 u - 2 u = 54
3 u = 54
1 u = 54 ÷ 3 = 18
Number of pears that she had at first
= 2 u
= 2 x 18
= 36
Answer(s): 36
