Jade had an equal number of pears and apples at first. She sold two-thirds of the apples and bought another 42 pears. In the end, she had five times as many pears as apples. Find the number of apples she had at first.

| Before |
3 u |
5 u - 42 |
| Change |
- 2 u |
+ 42 |
| After |
1 u |
5 u |
The number of pears and apples at first is the same.
5 u - 42 = 3 u
5 u - 3 u = 42
2 u = 42
1 u = 42 ÷ 2 = 21
Number of apples that she had at first
= 3 u
= 3 x 21
= 63
Answer(s): 63
