Julie had an equal number of kiwis and mangoes at first. She sold one-third of the mangoes and bought another 27 kiwis. In the end, she had six times as many kiwis as mangoes. Find the number of mangoes she had at first.

Kiwis |
Mangoes |
| Before |
12 u - 27 |
3 u |
| Change |
+ 27 |
- 1 u |
| After |
12 u |
2 u |
The number of kiwis and mangoes at first is the same.
12 u - 27 = 3 u
12 u - 3 u = 27
9 u = 27
1 u = 27 ÷ 9 = 3
Number of mangoes that Julie had at first
= 3 u
= 3 x 3
= 9
Answer(s): 9
