In an election only two candidates contested. A candidate secured 70% of the valid votes and won by a majority of 180 votes. Find the total number of valid votes? Pick one.
A) 450
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 = 180 =&gt; 4x/10 = 180   =&gt; 4x = 1800 =&gt; x = 450.   450NSWER:450
