A store owner has 44 more mangosteens than pomegranates. After he sold 75% of the mangosteens and 20% of the pomegranates, he is left with 88 more pomegranates than mangosteens. What fraction of the fruits left were pomegranates?

	Mangosteens		Pomegranates
Comparing mangosteens and pomegranates at first	44 more
Before	4x5 = 20 u	+ 44	5x4 = 20 u
Change	- 3x5 = - 15 u	- 33	- 1x4 = - 4 u
After	1x5 = 5 u	+ 11	4x4 = 16 u
Comparing mangosteens  and pomegranates in the end			88 more

75% = ⁷⁵₁₀₀ = ³₄ 
75% x 44 = ³₄ x 44 = 33
44 - 33 = 11

20% = ²⁰₁₀₀ = ¹₅ 

The number of pomegranates is 88 more than the number of mangosteens in the end. So, if another 88 mangosteens are added, the number of mangosteens and pomegranates in the end will be the same.

5 u + 11 + 88 = 16 u
5 u + 99 = 16 u
16 u - 5 u = 99
11 u = 99

1 u = 99 ÷ 11 = 9

Number of pomegranates left
= 16 u
= 16 x 9
= 144

Total number of fruits left
= 5 u + 11 + 16 u
= 21 u + 11
= 21 x 9 + 11
= 189 + 11
= 200

^{Pomegranates left}_{Total fruits left} = ¹⁴⁴₂₀₀ = ¹⁸₂₅

Answer(s): ¹⁸₂₅
