A store owner has 70 less pomegranates than apples. After he sold 60% of the pomegranates and 10% of the apples, he is left with 7 less pomegranates than apples. What fraction of the fruits left were pomegranates?

	Pomegranates		Apples
Comparing pomegranates and apples at first			70 less
Before	5x2 = 10 u	+ 70	10x1 = 10 u
Change	- 3x2 = - 6 u	- 42	- 1x1 = - 1 u
After	2x2 = 4 u	+ 28	9x1 = 9 u
Comparing pomegranates  and apples in the end	7 less

60% = ⁶⁰₁₀₀ = ³₅ 
60% x 70 = ³₅ x 70 = 42
70 - 42 = 28

10% = ¹⁰₁₀₀ = ¹₁₀ 

The number of pomegranates is 7 less than the number of apples in the end. So, if another 7 pomegranates are added, the number of pomegranates and apples in the end will be the same.

4 u + 28 + 7 = 9 u
4 u + 35 = 9 u
9 u - 4 u = 35
5 u = 35

1 u = 35 ÷ 5 = 7

Number of pomegranates left
= 4 u + 28
= 4 x 7 + 28
= 28 + 28
= 56

Total number of fruits left
= 4 u + 28 + 9 u
= 13 u + 28
= 13 x 7 + 28
= 91 + 28
= 119

^{Pomegranates left}_{Total fruits left} = ⁵⁶₁₁₉ = ⁸₁₇

Answer(s): ⁸₁₇
