A fruit stall had 3 times as many kiwis as peaches. After 4 kiwis were added, the number of kiwis became 28 more than the number of peaches. How many peaches were there at the fruit stall at first?

Kiwis |
Peaches |
| Before |
3 u |
1 u |
| Change |
+ 4 |
|
| After |
3 u + 4 |
1 u |
If another 4 peaches are added, the number of kiwis and peaches will be the same.
3 u + 4 = 1 u + 28
3 u - 1 u = 28 - 4
2 u = 24
1 u = 24 ÷ 2 = 12
Number of peaches at the fruit stall at first
= 1 u
= 12
Answer(s): 12
