A fruit stall had 5 times as many pears as passion fruits. After 5 pears were added, the number of pears became 21 more than the number of passion fruits. How many passion fruits were there at the fruit stall at first?

Pears |
Passion Fruits |
| Before |
5 u |
1 u |
| Change |
+ 5 |
|
| After |
5 u + 5 |
1 u |
If another 5 passion fruits are added, the number of pears and passion fruits will be the same.
5 u + 5 = 1 u + 21
5 u - 1 u = 21 - 5
4 u = 16
1 u = 16 ÷ 4 = 4
Number of passion fruits at the fruit stall at first
= 1 u
= 4
Answer(s): 4
