A fruit stall had 5 times as many chikoos as passion fruits. After 21 passion fruits were added, the number of chikoos became twice the number of the passion fruits. How many passion fruits were there at the fruit stall at first?
| |
Chikoos |
Passion Fruits |
| Before |
5x2 =
10 u |
1x2 =
2 u |
| Change |
|
+ 21 |
| After |
2x5 =
10 u |
1x5 =
5 u |
The number of chikoos remains unchanged. Make the number of chikoos the same. LCM of 2 and 5 is 10.
Number of passion fruits added
= 5 u - 2 u
= 3 u
3 u = 21
1 u = 21 ÷ 3 = 7
Number of passion fruits at the fruit stall at first
= 2 u
= 2 x 7
= 14
Answer(s): 14
