In an election, a candidate got 65% of the votes and won by a margin of 900 votes. Find the total number of votes.

Correct option is C

Given:

Winning candidate got 65% of the votes
Margin of victory = 900 votes

Formula Used:
Received Vote% = $$\frac{\text{Vote received}}{\text{total vote}}\times 100$$​​

Solution: 

If one candidate gets 65%, the other gets 35%
So, the margin is (65% − 35%) = 30% of total votes

​$$30\% \text{ of total votes} = 900\\ \ \\ \Rightarrow \frac{30}{100} \times \text{Total Votes} = 900$$​​

​$$\text{Total Votes} = \frac{900 \times 100}{30} = 3000$$​​

Thus, the correct option is (c) 3000
