SOLUTION

The selling price of an article is equal to the cost of the article plus the markup. The markup on a certain television set is what percent of the selling price?

Given: Price=Cost+Markup.

Question: \frac{Markup}{Price}=?

(1) The markup on the television set is 25 percent of the cost. Markup=0.25*Cost --> Price=Cost+Markup=Cost+0.25*Cost=1.25*Cost --> \frac{Markup}{Price}=\frac{0.25*Cost}{1.25*Cost}=0.2. Sufficient.

(2) The selling price of the television set is $250. Not sufficient to get the ratio required.

Hi Bunuel,

I understand why statement A is correct, but I don't understand why in this case the answer can't be C. If we use both the statements together, we have Selling Price = 1.25*Cost and the 2nd statement tells us the price.

If Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question asked, then the answer is A.

The data sufficiency problem consists of a question and two statements, labeled (1) and (2), in which certain data are given. You have to decide whether the data given in the statements are sufficient for answering the question. Using the data given in the statements, plus your knowledge of mathematics and everyday facts (such as the number of days in July or the meaning of the word counterclockwise), you must indicate whether—

A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question asked.

B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked.

C. BOTH statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient to answer the question asked.

D. EACH statement ALONE is sufficient to answer the question asked.

E. Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed.
