A fruit stall had 4 times as many chikoos as dragonfruits. After 14 dragonfruits were sold, the number of chikoos became 12 times the number of the remaining dragonfruits. How many dragonfruits were there at the fruit stall at first?
| |
Chikoos |
Dragonfruits |
| Before |
4x3 =
12 u |
1x3 =
3 u |
| Change |
|
- 14 |
| After |
12 u |
1 u |
The number of chikoos remains unchanged. Make the number of chikoos the same. LCM of 4 and 12 is 12.
Number of dragonfruits in the end = 3 u - 14
3 u - 14 = 1 u
3 u - 1 u = 14
2 u = 14
1 u = 14 ÷ 2 = 7
Number of dragonfruits at the fruit stall at first
= 3 u
= 3 x 7
= 21
Answer(s): 21
