In an election, contested by two candidates, 5% of the voters did not cast their votes. The winning candidate won by 4900 votes, securing 51% of the total votes. How many votes were cast for the winning candidate? Correct Answer 35,700
Given:
Winning candidate won by 4900 votes
Formula used:
Total votes = votes of the winner candidate + votes of the looser candidate
The difference of votes = votes of the winner candidate – votes of the looser candidate
Calculation:
Let total votes be x
Number of voters did not cast their votes = 5% of x = x/20
The winning candidate got votes = 51% of x = 51x/100
The number of votes losing candidate got = (x – x/20 – 51x/100) = 11x/25
Difference of votes = 51x/100 – 11x/25
⇒ 4900 = 7x/100
⇒ x = 70000
Votes cast for winning candidate = (51 × 70000)/100 = 35700
∴ The number of votes cast for winning candidate is 35700
Let the number of votes be 100%
The number of votes winning candidate got = 51%
The number of votes losing candidate got = (100% – 5% – 51%) = 44%
The difference in votes = 51% – 44% = 7%
Now, 7% = 4900
Then, 51% = 4900/7% × 51% = 35700
∴ The number of votes cast for winning candidate is 35700
Mistake Points Here the winning candidate got 51% of the total votes not of the valid votes.
