Show answer & explanation

Correct answer: A

Explanation

The correct answer is Option 1 i.e. 200000.

Given that

65% of the voters cast their votes, out of which 3% of the votes were decided to be invalid

A candidate got 81965 votes which is 65% of the total valid votes

According to the question

⇒ 65/100 × Total valid votes = 81965 

Total valid votes = 81965 × 100/65 = 126100

Let the total number of votes be 100 units

The number of valid votes = 100 × 0.65 × 0.97 = 63.05 units

⇒ 63.05 units = 126100

⇒ 100 units = 126100 × 100/63.05 = 200000 Votes
