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