A store owner has 72 more apples than pomegranates. After he sold 75% of the apples and 30% of the pomegranates, he is left with 36 less apples than pomegranates. What fraction of the fruits left were pomegranates?

	Apples		Pomegranates
Comparing apples and pomegranates at first	72 more
Before	4x5 = 20 u	+ 72	10x2 = 20 u
Change	- 3x5 = - 15 u	- 54	- 3x2 = - 6 u
After	1x5 = 5 u	+ 18	7x2 = 14 u
Comparing apples  and pomegranates in the end	36 less

75% = ⁷⁵₁₀₀ = ³₄ 
75% x 72 = ³₄ x 72 = 54
72 - 54 = 18

30% = ³⁰₁₀₀ = ³₁₀ 

The number of apples is 36 less than the number of pomegranates in the end. So, if another 36 apples are added, the number of apples and pomegranates in the end will be the same.

5 u + 18 + 36 = 14 u
5 u + 54 = 14 u
14 u - 5 u = 54
9 u = 54

1 u = 54 ÷ 9 = 6

Number of pomegranates left
= 14 u
= 14 x 6
= 84

Total number of fruits left
= 5 u + 18 + 14 u
= 19 u + 18
= 19 x 6 + 18
= 114 + 18
= 132

^{Pomegranates left}_{Total fruits left} = ⁸⁴₁₃₂ = ⁷₁₁

Answer(s): ⁷₁₁
