A store owner has 68 more starfruits than passion fruits. After he sold 75% of the starfruits and 30% of the passion fruits, he is left with 64 more passion fruits than starfruits. What fraction of the fruits left were passion fruits?

	Starfruits		Passion fruits
Comparing starfruits and passion fruits at first	68 more
Before	4x5 = 20 u	+ 68	10x2 = 20 u
Change	- 3x5 = - 15 u	- 51	- 3x2 = - 6 u
After	1x5 = 5 u	+ 17	7x2 = 14 u
Comparing starfruits  and passion fruits in the end			64 more

75% = ⁷⁵₁₀₀ = ³₄ 
75% x 68 = ³₄ x 68 = 51
68 - 51 = 17

30% = ³⁰₁₀₀ = ³₁₀ 

The number of passion fruits is 64 more than the number of starfruits in the end. So, if another 64 starfruits are added, the number of starfruits and passion fruits in the end will be the same.

5 u + 17 + 64 = 14 u
5 u + 81 = 14 u
14 u - 5 u = 81
9 u = 81

1 u = 81 ÷ 9 = 9

Number of passion fruits left
= 14 u
= 14 x 9
= 126

Total number of fruits left
= 5 u + 17 + 14 u
= 19 u + 17
= 19 x 9 + 17
= 171 + 17
= 188

^{Passion fruits left}_{Total fruits left} = ¹²⁶₁₈₈ = ⁶³₉₄

Answer(s): ⁶³₉₄
