A store owner had an equal number of dragonfruits, passion fruits and persimmons at first. After 58 persimmons, some dragonfruits and passion fruits were sold, there were 121 fruits left. There were 2 times as many dragonfruits as passion fruits left. The number of persimmons left was 24 less than the number of dragonfruits left. How many passion fruits were sold?

	Dragonfruits	Passion Fruits	Persimmons	Total
Before	1	1	1
Change	- ?	- ?	- 58
After	2 u	1 u	2 u - 24	121

Total number of fruits in the end
= 2 u + 1 u + 2 u - 24
= 5 u - 24

5 u - 24 = 121
5 u = 121 + 24
5 u = 145

1 u = 145 ÷ 5 = 29

Number of persimmons at first
= 2 u - 24 + 58 
= 2 x 29 + 34 
= 92 

The number of persimmons and passion fruits at first is the same.

Number of passion fruits sold
= 92 - 29
= 63

Answer(s): 63
