A fruit stall had 4 times as many guavas as starfruits. After 11 guavas were added, the number of guavas became 23 more than the number of starfruits. How many starfruits were there at the fruit stall at first?

Guavas |
Starfruits |
| Before |
4 u |
1 u |
| Change |
+ 11 |
|
| After |
4 u + 11 |
1 u |
If another 11 starfruits are added, the number of guavas and starfruits will be the same.
4 u + 11 = 1 u + 23
4 u - 1 u = 23 - 11
3 u = 12
1 u = 12 ÷ 3 = 4
Number of starfruits at the fruit stall at first
= 1 u
= 4
Answer(s): 4
