A store owner has 64 more chikoos than pomegranates. After he sold 75% of the chikoos and 20% of the pomegranates, he is left with 28 more pomegranates than chikoos. What fraction of the fruits left were pomegranates?

	Chikoos		Pomegranates
Comparing chikoos and pomegranates at first	64 more
Before	4x5 = 20 u	+ 64	5x4 = 20 u
Change	- 3x5 = - 15 u	- 48	- 1x4 = - 4 u
After	1x5 = 5 u	+ 16	4x4 = 16 u
Comparing chikoos  and pomegranates in the end			28 more

75% = ⁷⁵₁₀₀ = ³₄ 
75% x 64 = ³₄ x 64 = 48
64 - 48 = 16

20% = ²⁰₁₀₀ = ¹₅ 

The number of pomegranates is 28 more than the number of chikoos in the end. So, if another 28 chikoos are added, the number of chikoos and pomegranates in the end will be the same.

5 u + 16 + 28 = 16 u
5 u + 44 = 16 u
16 u - 5 u = 44
11 u = 44

1 u = 44 ÷ 11 = 4

Number of pomegranates left
= 16 u
= 16 x 4
= 64

Total number of fruits left
= 5 u + 16 + 16 u
= 21 u + 16
= 21 x 4 + 16
= 84 + 16
= 100

^{Pomegranates left}_{Total fruits left} = ⁶⁴₁₀₀ = ¹⁶₂₅

Answer(s): ¹⁶₂₅
