Let's compute bananas first. Apples 8%, Bananas 28% and Oranges 56%

Explanation:

Let's start with Bananas (only unknown parameter and one equation):

The equation will be (B is for bananas, O is for oranges and A is for apples. Total votes for these (92). Total votes 100.
#2B+B+(B-20))=92#

#4B-20=92#
and #B=28#
Oranges are twice this amount: #O=56#
Apples get 20 percent less than bananas #A=28-20=8#
Total percentage (of these three) is 92.

Summary:
Apples got 8%, Bananas got 28% and Oranges got 56% of the votes.
