A fruit stall had 5 times as many dragonfruits as chikoos. After 11 dragonfruits were added, the number of dragonfruits became 15 more than the number of chikoos. How many chikoos were there at the fruit stall at first?

Dragonfruits |
Chikoos |
| Before |
5 u |
1 u |
| Change |
+ 11 |
|
| After |
5 u + 11 |
1 u |
If another 11 chikoos are added, the number of dragonfruits and chikoos will be the same.
5 u + 11 = 1 u + 15
5 u - 1 u = 15 - 11
4 u = 4
1 u = 4 ÷ 4 = 1
Number of chikoos at the fruit stall at first
= 1 u
= 1
Answer(s): 1
