Question 81502
This can be solved in a few ways, but this should work :
--
let w = winning candidate's votes.
The loser got 220 less than this, so he/she got w-220 votes.
--
The total number of votes is the winner's plus the loser's added together
So :  w + (w-220) = 810
Add 220 to both sides
w + w = 1030
w = 515  (ie the winning candidate got 515 votes)
From this, we can then easily work out, the losing candidate must have got 295 votes.
