• 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}
