A fruit stall had 4 times as many persimmons as kiwis. After 12 kiwis were sold, the number of persimmons became 12 times the number of the remaining kiwis. How many kiwis were there at the fruit stall at first?
| |
Persimmons |
Kiwis |
| Before |
4x3 =
12 u |
1x3 =
3 u |
| Change |
|
- 12 |
| After |
12 u |
1 u |
The number of persimmons remains unchanged. Make the number of persimmons the same. LCM of 4 and 12 is 12.
Number of kiwis 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 kiwis at the fruit stall at first
= 3 u
= 3 x 6
= 18
Answer(s): 18
