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 andR = 125. We have 25 % that is what we are looking for SUFF

B shoould be the answer

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:
1. Please provide your solutions to the questions;
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.

Answer B.

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.

Answer: B.

Kudos points given to everyone with correct solution. Let me know if I missed someone.
