Question
In a village election between two candidates, the winner
secured 54% of the total votes cast and won by a majority of 4000 votes. How many votes did the losing candidate get?Solution
Total votes cast = 100% % of votes secured by winner = 54% % of votes secured by loser = 100 – 54 = 46% Majority = Votes secured by winner – Votes secured by loser = 54% – 46% = 8% Votes secured by losing candidate = 46/8 × 4000 = 23000
