A fruit stall had 3 times as many mangosteens as chikoos. After 12 mangosteens were added, the number of mangosteens became 24 more than the number of chikoos. How many chikoos were there at the fruit stall at first?

Mangosteens |
Chikoos |
| Before |
3 u |
1 u |
| Change |
+ 12 |
|
| After |
3 u + 12 |
1 u |
If another 12 chikoos are added, the number of mangosteens and chikoos will be the same.
3 u + 12 = 1 u + 24
3 u - 1 u = 24 - 12
2 u = 12
1 u = 12 ÷ 2 = 6
Number of chikoos at the fruit stall at first
= 1 u
= 6
Answer(s): 6
