A fruit stall had 5 times as many peaches as chikoos. After 9 chikoos were added, the number of peaches became twice the number of the chikoos. How many chikoos were there at the fruit stall at first?
| |
Peaches |
Chikoos |
| Before |
5x2 =
10 u |
1x2 =
2 u |
| Change |
|
+ 9 |
| After |
2x5 =
10 u |
1x5 =
5 u |
The number of peaches remains unchanged. Make the number of peaches the same. LCM of 2 and 5 is 10.
Number of chikoos added
= 5 u - 2 u
= 3 u
3 u = 9
1 u = 9 ÷ 3 = 3
Number of chikoos at the fruit stall at first
= 2 u
= 2 x 3
= 6
Answer(s): 6
