Correct Answer: 2,00,000


Solution : Let the total number of voters registered be $x$.
65% of the voters cast their votes.
Casted votes = $\frac{65x}{100}$
3% of cast votes were declared invalid.
Valid votes = $\frac{97}{100}×\frac{65x}{100}$
A candidate got 81965 votes which are 65% of the total valid votes.
So, $\frac{97}{100}×\frac{65x}{100}×\frac{65}{100}=81965$
$⇒x=\frac{81965×100×100×100}{65×65×97}$
$\therefore x = 200000$
Hence, the correct answer is 2,00,000.
