A store owner has 75 less lemons than pomegranates. After he sold 60% of the lemons and 10% of the pomegranates, he is left with 10 less lemons than pomegranates. What fraction of the fruits left were lemons?

	Lemons		Pomegranates
Comparing lemons and pomegranates at first			75 less
Before	5x2 = 10 u	+ 75	10x1 = 10 u
Change	- 3x2 = - 6 u	- 45	- 1x1 = - 1 u
After	2x2 = 4 u	+ 30	9x1 = 9 u
Comparing lemons  and pomegranates in the end	10 less

60% = ⁶⁰₁₀₀ = ³₅ 
60% x 75 = ³₅ x 75 = 45
75 - 45 = 30

10% = ¹⁰₁₀₀ = ¹₁₀ 

The number of lemons is 10 less than the number of pomegranates in the end. So, if another 10 lemons are added, the number of lemons and pomegranates in the end will be the same.

4 u + 30 + 10 = 9 u
4 u + 40 = 9 u
9 u - 4 u = 40
5 u = 40

1 u = 40 ÷ 5 = 8

Number of lemons left
= 4 u + 30
= 4 x 8 + 30
= 32 + 30
= 62

Total number of fruits left
= 4 u + 30 + 9 u
= 13 u + 30
= 13 x 8 + 30
= 104 + 30
= 134

^{Lemons left}_{Total fruits left} = ⁶²₁₃₄ = ³¹₆₇

Answer(s): ³¹₆₇
