A fruit stall had 6 times as many dragonfruits as passion fruits. After 16 passion fruits were added, the number of dragonfruits became twice the number of the passion fruits. How many passion fruits were there at the fruit stall at first?
| |
Dragonfruits |
Passion Fruits |
| Before |
6x1 =
6 u |
1x1 =
1 u |
| Change |
|
+ 16 |
| After |
2x3 =
6 u |
1x3 =
3 u |
The number of dragonfruits remains unchanged. Make the number of dragonfruits the same. LCM of 2 and 6 is 6.
Number of passion fruits added
= 3 u - 1 u
= 2 u
2 u = 16
1 u = 16 ÷ 2 = 8
Number of passion fruits at the fruit stall at first
= 1 u
= 1 x 8
= 8
Answer(s): 8
