A store owner has 55 more passion fruits than oranges. After he sold 60% of the passion fruits and 35% of the oranges, he is left with 8 more oranges than passion fruits. What fraction of the fruits left were oranges?

	Passion fruits		Oranges
Comparing passion fruits and oranges at first	55 more
Before	5x4 = 20 u	+ 55	20x1 = 20 u
Change	- 3x4 = - 12 u	- 33	- 7x1 = - 7 u
After	2x4 = 8 u	+ 22	13x1 = 13 u
Comparing passion fruits  and oranges in the end			8 more

60% = ⁶⁰₁₀₀ = ³₅ 
60% x 55 = ³₅ x 55 = 33
55 - 33 = 22

35% = ³⁵₁₀₀ = ⁷₂₀ 

The number of oranges is 8 more than the number of passion fruits in the end. So, if another 8 passion fruits are added, the number of passion fruits and oranges in the end will be the same.

8 u + 22 + 8 = 13 u
8 u + 30 = 13 u
13 u - 8 u = 30
5 u = 30

1 u = 30 ÷ 5 = 6

Number of oranges left
= 13 u
= 13 x 6
= 78

Total number of fruits left
= 8 u + 22 + 13 u
= 21 u + 22
= 21 x 6 + 22
= 126 + 22
= 148

^{Oranges left}_{Total fruits left} = ⁷⁸₁₄₈ = ³⁹₇₄

Answer(s): ³⁹₇₄
