Q:

In an election only two candidates contested 20% of the voters did not vote and 120 votes were declared as invalid.

A) 47.5%	B) 41%
C) 38%	D) 45%

Let there be x voters and k votes goes to loser then

0.8x - 120 = k + (k + 200)

k+200 = 0.41x

=> k = 1440

and (k + 200) =1640

Therefore 1440/3200 x 100 = 45%
