In an election between two candidates, 10% of the registered voters did not cast their vote. The winning candidate got 60% of the total votes cast and defeated the other candidate by 1242 votes. Find the total number of registered voters.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 6900.
Let the total number of registered voters be 100x
Total casted votes = 90% of 100x = 90x
Number of votes winning candidate got = 60% of 90x = 54x
Number of votes losing candidate got = 90x - 54x = 36x
According to the question;
⇒ 54x - 36x = 1242
⇒ 18x = 1242
⇒ x = 69
Hence, the total number of registered voters = 100x = 100 × 69 = 6900
