A fruit stall had 3 times as many persimmons as kiwis. After 8 persimmons were added, the number of persimmons became 20 more than the number of kiwis. How many kiwis were there at the fruit stall at first?

Persimmons |
Kiwis |
| Before |
3 u |
1 u |
| Change |
+ 8 |
|
| After |
3 u + 8 |
1 u |
If another 8 kiwis are added, the number of persimmons and kiwis will be the same.
3 u + 8 = 1 u + 20
3 u - 1 u = 20 - 8
2 u = 12
1 u = 12 ÷ 2 = 6
Number of kiwis at the fruit stall at first
= 1 u
= 6
Answer(s): 6
