  • 14. In an election between two candidates, 75 % of the voters cast their votes, out of which 2% of the votes were declared invalid. A candidate got 9261 votes which were 75% of the total valid votes. Find the total number of votes.

    1. 16800
    2. 15800
    3. 16700
    4. 15700
    Answer And Explanation

    Answer: Option A

    Explanation:

    Let the total number of votes enrolled are x.
    Number of votes cast = 75% of x
    Valid votes = 98% of 75% of x

    Now, as 9261 is the 75% of valid casted votes so,

    75% of 98% of 75% of x = 9261 [imporant]

    \begin{align}
    => \frac{75 \times 98 \times 75 \times x}{100 \times 100 \times 100} = 9261 \\

    => x = 16800
    \end{align}
