In a corporation election, two candidates fought for the post of Mayor. One candidate got 40% of the valid votes. 23% of the votes were invalid. If the total votes were 21000, what is the number of valid votes that the other candidate got?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 9702.
Total votes = 21,000
Invalid votes = 23% of 21,000 = 4,830
Valid votes = 21000 − 4830 = 16,170
One candidate got 40% of valid votes = × 16170 = 6,468
Other candidate got = 16170 − 6468 = 9702
