Question 82605: In local election 2 candidates stood for office.
After results the loser concluded by saying "The winning margin of my opponent
was a mere 6 2/3% (six and two thirds percent) of the Total votes"
The loser also said that if he could have persuaded 12 people to vote for him instead of his opponent then he would have won office by a mere 1 vote.
How many voted for each candidate???
---------------------------------------
So far i get the following
TOTALvotes=X votes + Y votes
Winning margin =(20/3)% x TOTALvotes = 0.0666666 x TOTALvotes
(LOSERvotes + 12)-(WINNERvotes - 12)=1
---------------------------------------
I dont know how to proceed any further. Can you please assist?
