A fruit stall had 3 times as many pears as chikoos. After 8 pears were added, the number of pears became 30 more than the number of chikoos. How many chikoos were there at the fruit stall at first?

Pears |
Chikoos |
| Before |
3 u |
1 u |
| Change |
+ 8 |
|
| After |
3 u + 8 |
1 u |
If another 8 chikoos are added, the number of pears and chikoos will be the same.
3 u + 8 = 1 u + 30
3 u - 1 u = 30 - 8
2 u = 22
1 u = 22 ÷ 2 = 11
Number of chikoos at the fruit stall at first
= 1 u
= 11
Answer(s): 11
