    D 15000 Correct Answer Incorrect Answer

    Solution

    Let the total number of votes polled be x. Number of valid votes = 80% of x Number of votes secured by P = 30% of  80% of x Remaining valid votes = 70% of 80% of x Number of votes secured by R = (9/20) of 70% of 80% of x Votes received by P = Votes received by R - 150 => 30% of  80% of x = (9/20) of 70% of 80% of x - 150 => 150 = (9/20) of 56% of x - 24% of x => x = 12500 ∴ The total votes polled was 12500.
