A store owner has 45 less oranges than pomegranates. After he sold 60% of the oranges and 35% of the pomegranates, he is left with 12 less oranges than pomegranates. What fraction of the fruits left were oranges?

	Oranges		Pomegranates
Comparing oranges and pomegranates at first			45 less
Before	5x4 = 20 u	+ 45	20x1 = 20 u
Change	- 3x4 = - 12 u	- 27	- 7x1 = - 7 u
After	2x4 = 8 u	+ 18	13x1 = 13 u
Comparing oranges  and pomegranates in the end	12 less

60% = ⁶⁰₁₀₀ = ³₅ 
60% x 45 = ³₅ x 45 = 27
45 - 27 = 18

35% = ³⁵₁₀₀ = ⁷₂₀ 

The number of oranges is 12 less than the number of pomegranates in the end. So, if another 12 oranges are added, the number of oranges and pomegranates in the end will be the same.

8 u + 18 + 12 = 13 u
8 u + 30 = 13 u
13 u - 8 u = 30
5 u = 30

1 u = 30 ÷ 5 = 6

Number of oranges left
= 8 u + 18
= 8 x 6 + 18
= 48 + 18
= 66

Total number of fruits left
= 8 u + 18 + 13 u
= 21 u + 18
= 21 x 6 + 18
= 126 + 18
= 144

^{Oranges left}_{Total fruits left} = ⁶⁶₁₄₄ = ¹¹₂₄

Answer(s): ¹¹₂₄
