Hi All,
We're told that a merchant purchased a sofa from a manufacturer for $400 and then sold it. We're asked for the selling price of the sofa. This question is based around a mix of basic Arithmetic and Algebra.
(1) The selling price of the sofa was greater than 140 percent of the purchase price.
Fact 1 tells us that the selling price was GREATER than 140% of $400, so there's clearly a limitless number of possibilities. There's no way to determine the exact selling price, although we know that it would be MORE than (1.4)($400) = $560.
Fact 1 is INSUFFICIENT
(2) The merchant's gross profit from the purchase and sale of the sofa was 1/3 of the selling price.
Based on the information in Fact 2, we can create the following equation:
Profit = (Selling Price) - (Cost)
(1/3)(P) = (P) - 400
This is one variable and one equation, so you CAN solve for P (and there will be just one answer. If you did the extra steps, you would come up with the following:
P = 3P - 1200
1200 = 2P
600 = P
Fact 2 is SUFFICIENT
