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