Emily had an equal number of kiwis and pears at first. She sold two-thirds of the pears and bought another 90 kiwis. In the end, she had five times as many kiwis as pears. Find the number of pears she had at first.

Pears |
Kiwis |
| Before |
3 u |
5 u - 90 |
| Change |
- 2 u |
+ 90 |
| After |
1 u |
5 u |
The number of kiwis and pears at first is the same.
5 u - 90 = 3 u
5 u - 3 u = 90
2 u = 90
1 u = 90 ÷ 2 = 45
Number of pears that she had at first
= 3 u
= 3 x 45
= 135
Answer(s): 135
