1. Real-estate salesman Z is selling a house at a 20 percent discount from its retail price.
2. Real-estate salesman X vows to match this price, and then offers an additional 10 percent discount.
3. Real-estate salesman Y decides to average the prices of salesmen Z and X, then offer an additional 25 percent discount.
Asked: Salesman Y's final price is what fraction of salesman X's final price?
Let the retail price of the house be x
Z is selling it @ .80x
X is selling it @ .8*.9x = .72x
Y is selling it @ .76x*.75
Salesman Y's final price is what fraction of salesman X's final price = .76x*.75/.72x = 19/18*(3/4) = 19/6*4 = 19/24
