A fruit stall had 3 times as many lemons as chikoos. After 15 chikoos were sold, the number of lemons became 12 times the number of the remaining chikoos. How many chikoos were there at the fruit stall at first?
| |
Lemons |
Chikoos |
| Before |
3x4 =
12 u |
1x4 =
4 u |
| Change |
|
- 15 |
| After |
12 u |
1 u |
The number of lemons remains unchanged. Make the number of lemons the same. LCM of 3 and 12 is 12.
Number of chikoos in the end = 4 u - 15
4 u - 15 = 1 u
4 u - 1 u = 15
3 u = 15
1 u = 15 ÷ 3 = 5
Number of chikoos at the fruit stall at first
= 4 u
= 4 x 5
= 20
Answer(s): 20
