Two candidates fought an election. One of them got 65% of the total votes casted and won by 420 votes. What is the total number of votes polled if no vote is declared invalid?

Correct option is B

Let total vote = 100 unit
Winner’s vote = 65 unit
Looser’s vote = 100 – 65 = 35 unit
Difference between Winner and looser = 65 – 35 = 30 unit
ATQ.
30 unit = 420 votes
