in a mayoral election , candidate x received 1 / 5 more votes than candidate y , and candidate y received 1 / 2 fewer votes than z . if z received 20,000 votes how many votes did candidate x received ?
"z = 20 - - > y received 1 / 2 fewer votes than z - - > y = z - 1 / 2 * z = 10 ; x received 1 / 5 more votes than y - - > x = y + 1 / 5 * y = 12 . answer : a ."
