A fruit stall had 5 times as many pomegranates as passion fruits. After 15 passion fruits were added, the number of pomegranates became twice the number of the passion fruits. How many passion fruits were there at the fruit stall at first?
| |
Pomegranates |
Passion Fruits |
| Before |
5x2 =
10 u |
1x2 =
2 u |
| Change |
|
+ 15 |
| After |
2x5 =
10 u |
1x5 =
5 u |
The number of pomegranates remains unchanged. Make the number of pomegranates the same. LCM of 2 and 5 is 10.
Number of passion fruits added
= 5 u - 2 u
= 3 u
3 u = 15
1 u = 15 ÷ 3 = 5
Number of passion fruits at the fruit stall at first
= 2 u
= 2 x 5
= 10
Answer(s): 10
