In an election only two candidates contested. A candidate secured 70% of the valid votes and won by a majority of 172 votes. Find the total number of valid votes ?
Solution
Correct Answer: Option D
Let the total number of valid votes be 'V'.
70% of V = 70/100 x V = 7V/10
Number of votes secured by the other candidate = V - 7V/100 = 3V/10
Given, 7V/10 - 3V/10 = 172 => 4V/10 = 172
=> 4V = 1720 => V = 430.
