A fruit stall had 3 times as many chikoos as starfruits. After 6 chikoos were added, the number of chikoos became 30 more than the number of starfruits. How many starfruits were there at the fruit stall at first?
| |
Chikoos |
Starfruits |
| Before |
3 u |
1 u |
| Change |
+ 6 |
|
| After |
3 u + 6 |
1 u |
If another 6 starfruits are added, the number of chikoos and starfruits will be the same.
3 u + 6 = 1 u + 30
3 u - 1 u = 30 - 6
2 u = 24
1 u = 24 ÷ 2 = 12
Number of starfruits at the fruit stall at first
= 1 u
= 12
Answer(s): 12
