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.

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

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.

(1) y - x = 20
(2) y/x = 5/4


We are given that a clothing store acquired an item at a cost of x dollars and sold the item for y dollars. We must determine:

(profit/cost) * 100 = ?

We are given x as the cost and y as the revenue. Thus, profit = revenue – cost = y – x, and thus we can substitute y – x for profit and x for cost. Thus, our new question is:

(y – x)/x * 100 = ?

Statement One Alone:

y – x = 20

Since y – x = 20, we can substitute 20 for y - x into the expression (y – x)/x * 100.

The new question is: 20/x * 100 = ?

Since we do not know the value of x, statement one alone is not sufficient.

Statement Two Alone:

y/x = 5/4

When we cross multiply y/x = 5/4 we obtain:

4y = 5x

(4/5)y = x

0.8y = x

Since 0.8y = x, we can substitute 0.8y for x in the expression (y – x)/x * 100.

(y – 0.8y)/(0.8y) * 100 = ?

(0.2y)/(0.8y) * 100 = ?

(0.2/0.8) * 100 = ?

(1/4) * 100 = 25%

Statement two is sufficient.

Answer: B
