SOLUTION

A clothing store acquired an item at a cost of x dollars and sold the item for y dollars. The store's gross profit from the item was what percent of its cost for the item?

We need to find the value of $$\frac{y-x}{x}*100=(\frac{y}{x}-\frac{x}{x})*100=(\frac{y}{x}-1)*100$$. So, basically we need to find the value of $$\frac{y}{x}$$.

(1) y - x = 20. We cannot get the desired ratio from this statement. Not sufficient.
(2) y/x = 5/4. Directly gives us the value of $$\frac{y}{x}$$. Sufficient.

tricky one. I picked D but is wrong. Answer should be B

here: $$P = Revenues - Costs$$. for instance I have $$R = 30$$ $$C = 10$$ so $$y - x = 20$$. In my example I know x and y but from 1) we do not have them sio INSUFF

2) $$y = 5$$ $$x = 4$$-----> $$R = 5$$ and $$C = 4$$ so $$C = 100$$ and$$R = 125$$. We have 25 % that is what we are looking for SUFF

GMAT Club is introducing a new project: The Official Guide for GMAT® Review, 13th Edition - Quantitative Questions Project

Each week we'll be posting several questions from The Official Guide for GMAT® Review, 13th Edition and then after couple of days we'll provide Official Answer (OA) to them along with a slution.

We'll be glad if you participate in development of this project:
2. Please vote for the best solutions by pressing Kudos button;
3. Please vote for the questions themselves by pressing Kudos button;
4. Please share your views on difficulty level of the questions, so that we have most precise evaluation.

Thank you!

The gross profit is $$y-x.$$ The question asks for the ratio $$\frac{y-x}{x}.$$

(1) No information about $$x.$$
Not sufficient.

(2) Since $$\frac{y-x}{x}=\frac{y}{x}-\frac{x}{x}=\frac{y}{x}-1$$, sufficient.

Your method to rephrase a stem is simply unbelievable. Of course the most important thing during the exam is to have the right solution under time constrain, no matter what......but wow
