Question

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?

Answer 1

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.

Answer:
=======

Let the total number of valid votes be 'V'.

$70$% of V

$= \frac{70}{100} \times v$

$= \frac{7v}{10}$

Number of votes secured by the other candidate

$= v - \frac{7v}{100}$

$= \frac{3v}{10}$

Given,

$\frac{7v}{10} - \frac{3v}{10} = 172$

$\frac{4v}{10} = 172$

$4v = 1720$

$v = 430$

Therefore,

Answer: 430
