A fruit stall had 4 times as many passion fruits as chikoos. After 12 chikoos were sold, the number of passion fruits became 12 times the number of the remaining chikoos. How many chikoos were there at the fruit stall at first?
| |
Passion Fruits |
Chikoos |
| Before |
4x3 =
12 u |
1x3 =
3 u |
| Change |
|
- 12 |
| After |
12 u |
1 u |
The number of passion fruits remains unchanged. Make the number of passion fruits the same. LCM of 4 and 12 is 12.
Number of chikoos in the end = 3 u - 12
3 u - 12 = 1 u
3 u - 1 u = 12
2 u = 12
1 u = 12 ÷ 2 = 6
Number of chikoos at the fruit stall at first
= 3 u
= 3 x 6
= 18
Answer(s): 18
