In an election between two candidates, 80% of the voters cast their votes, out of which 10% of the votes were declared invalid. A candidate got 9,936 votes which were 60% of the total valid votes. Find the total number of voters enrolled in that election.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 23000.
Let the total number of voters enrolled in the election = V
Number of votes cast = 0.80V
Valid votes = 0.90 × 0.80 × V = 0.72V
0.60 × 0.72V = 9936
⇒ 0.432V = 9936
⇒ V = 9936/0.432 = 23000
