75% of valid votes = 9261
Valid votes = (9261 * 4)/3 = 3087 * 4 = 12348

(75% - 1.5% = approx. 75%) of Total voters = 12348
Total voters = (12348 * 4)/3 = 4116 * 4 = Close to 16000

Answer: A

Total number of the enrolled voters=x

x*(0.75)*(0.98)*(0.75)=9261

x=16800

Correct answer is A

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 enrolled in that election.

As it seems 75% of the voters cast their votes I believe the ans X=(9261*100*100)/(98*75)=12600 Note - the question is total number of votes enrolled in election

If the question was total number of voters then ans X=(12600*100)/75=16800

hello, i want to ask a question. So, basically, the voting system work based on the US ballot system? In other word, 1 person is only able to cast one vote?

Answer: A


your answer is still unconvincing, it is because if the right answer is either C or D, there is no way to choose the answer using your method of calculation

Assuming total voters enrolled to be 100.

For 75% valid votes.. which makes # of votes as 75..
out of which 2% is invalid ..\(\frac{75*2}{100}\) = 1.5.. total valid votes are 75-1.5=73.5

Now for 73.5 votes 75% are valid .
By general cross method

100 - 73.5*75%
? - 9261

=>\(\frac{(9261*100)}{(75 \%*73.5 )}\)
=>\(\frac{(9261*100*100)}{(75*73.5)}\)
dividing by 25(100 & 75) and 7(9261 & 73.5) and then simplifying gives 16800

chesstitans, yes, in the U.S. the system is SUPPOSED to be one person, one vote.

I think there is a typo in the question. I think the question needs to ask about total voteRs, not votes. See sreenu7464 's post.
