A fruit stall had 6 times as many starfruits as lemons. After 14 lemons were added, the number of starfruits became twice the number of the lemons. How many lemons were there at the fruit stall at first?
| |
Starfruits |
Lemons |
| Before |
6x1 =
6 u |
1x1 =
1 u |
| Change |
|
+ 14 |
| After |
2x3 =
6 u |
1x3 =
3 u |
The number of starfruits remains unchanged. Make the number of starfruits the same. LCM of 2 and 6 is 6.
Number of lemons added
= 3 u - 1 u
= 2 u
2 u = 14
1 u = 14 ÷ 2 = 7
Number of lemons at the fruit stall at first
= 1 u
= 1 x 7
= 7
Answer(s): 7
