In an election only two candidates contested. A candidate secured 70% of the valid votes and won by a majority of 188 votes. Find the total number of valid votes?  Choose the correct choice from the following answers:
A) 430
B) 438
C) 436
D) 470
E) 422
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 = 188 =&gt; 4x/10 = 188   =&gt; 4x = 1880 =&gt; x = 470.   Answer:470
