Question

In an election between two candidates, first candidate get $80\%$ of the total valid votes. If $10\%$ of the total $1,80,000$ votes were declared invalid then the number of valid votes polled in favour of the second candidate are:

• A. $31400$
• B. $31500$
• C. $32400$
• D. $32420$

Answer 1

The correct option is C $32400$

Number of valid votes $=90\%$ of $1,80,000$ votes $=\frac{90}{100}\times 1,80,000$
$=1,62,000$
Number of votes polled in favour of first candidate $=80\%$ of $1,62,000$
$=\frac{80}{100}\times 1,62,000=1,29,600$
Number of votes polled in favour of second candidate $=1,62,000-1,29,600=32,400$.
