A fruit stall had 5 times as many starfruits as kiwis. After 14 kiwis were added, the number of starfruits became thrice the number of the kiwis. How many kiwis were there at the fruit stall at first?
| |
Starfruits |
Kiwis |
| Before |
5x3 =
15 u |
1x3 =
3 u |
| Change |
|
+ 14 |
| After |
3x5 =
15 u |
1x5 =
5 u |
The number of starfruits remains unchanged. Make the number of starfruits the same. LCM of 3 and 5 is 15.
Number of kiwis added
= 5 u - 3 u
= 2 u
2 u = 14
1 u = 14 ÷ 2 = 7
Number of kiwis at the fruit stall at first
= 3 u
= 3 x 7
= 21
Answer(s): 21
