A store owner has 40 more mangoes than passion fruits. After he sold 60% of the mangoes and 30% of the passion fruits, he is left with 8 more passion fruits than mangoes. What fraction of the fruits left were passion fruits?

	Mangoes		Passion fruits
Comparing mangoes and passion fruits at first	40 more
Before	5x2 = 10 u	+ 40	10x1 = 10 u
Change	- 3x2 = - 6 u	- 24	- 3x1 = - 3 u
After	2x2 = 4 u	+ 16	7x1 = 7 u
Comparing mangoes  and passion fruits in the end			8 more

60% = ⁶⁰₁₀₀ = ³₅ 
60% x 40 = ³₅ x 40 = 24
40 - 24 = 16

30% = ³⁰₁₀₀ = ³₁₀ 

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

4 u + 16 + 8 = 7 u
4 u + 24 = 7 u
7 u - 4 u = 24
3 u = 24

1 u = 24 ÷ 3 = 8

Number of passion fruits left
= 7 u
= 7 x 8
= 56

Total number of fruits left
= 4 u + 16 + 7 u
= 11 u + 16
= 11 x 8 + 16
= 88 + 16
= 104

^{Passion fruits left}_{Total fruits left} = ⁵⁶₁₀₄ = ⁷₁₃

Answer(s): ⁷₁₃
