In an election between two candidates, 90% of the voters cast their votes, out of which 5% of the votes were declared invalid. A candidate got 12825 votes, which were 75% of the total valid votes. Find the total number of voters enrolled in that election.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 20000.
Let total voters = x
90% voted = 0.9x
valid votes = 95% of 0.9x = 0.855x
12825 = 75% of valid votes
12825 = 0.75 × 0.855x
x = 20000
