Approximately what percent of the remaining votes would he need to have received in order to have won at least 50 percent of all the votes cast? Choose the correct answer. A) 10% B) 12% ...
Lets assume that candidate got 40% votes and total votes is 100. Candidate won = 40 Remaining = 60 To get 50%, candidate requires 10 votes from 100 which is 10% and 10 votes from 60. 10/60 = 1/6 = .166 = 16.67% Which is approx 17%. Hence the answer is 17% <result>D</result>
