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?	Select:  A) 430  B) 570  C) 480  D) 520  E) 550
Let the total number of valid votes be x.   70% of x = 70/100 * x = 7x/10   Number of votes secured by the other candidate = x - 7x/100 = 3x/10   Given, 7x/10 - 3x/10 = 172 =&gt; 4x/10 = 172   =&gt; 4x = 1720 =&gt; x = 430.   430NSWER:430
