In an election between two candidates, one got \(55 \%\) of the total votes, \(20 \%\) of the votes are invalid. If the total votes are 7500 , what is the number of valid votes that the other candidate got?
A. 2700 B. 3900 C. 3000 D. 3100
Correct Answer: A
Explanation
First we get the total valid votes. Since \(20 \%\) of the votes are invalid, it means \(80 \%\) of the total votes are valid. Hence, Total valid votes \(=\frac{80 \times 7500}{100}=6000\) The other candidate gets \((100 \%-55 \%)\) i.e. \(45 \%\) of the total valid votes Hence, \(\frac{45 \times 6000}{100}=2700 \quad\)
