2) INSUFF
No information on the markup and cost

Incorrect, see answer below.

(1) The markup on the television set is 25 percent of the cost.
(2) The selling price of the television set is $250.
A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D. EACH statement ALONE is sufficient.
E. Statements (1) and (2) TOGETHER are NOT sufficient.


Answer should be A:

C + M = S


st.1 M = 0.25C

C + 0.25C = S
C = S/1.25
M = (0.25/1.25) * S .......SUFF

st.2 INSUFF

Rephrasing the question
Price = Cost + Markup
Mark up % = Markup / Price

i) Markup = 25% of Cost
M = 0.25C
P = 0.25 Cost + 1 Cost
P = 1.25 Cost

Markup % = 0.25/1.25 (Cancel the C)
Markup % = 20%

ii) Price = $250
250 = C + M
Linear equation. Two unknown variables. Not solveable

Expert's post
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.

Answer: A.
