    Question

    In an election between two candidates X and Y, 12% of all

    votes were declared invalid. Candidate X secured 60% of the valid votes. If candidate Y got 17,136 valid votes, find the total number of votes cast.
    A 48,700 Correct Answer Incorrect Answer
    B 54,000 Correct Answer Incorrect Answer
    C 60,000 Correct Answer Incorrect Answer
    D 75,100 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let the total number of votes be 100n

    Valid votes = 0.88 × 100n = 88n

    Valid votes received by Y = 0.40 × 88n = 35.2n

    So, 35.2n = 17,136

    ⇒ n = 487

    Therefore, total number of votes = 487 × 100 = 48,700
