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?
(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.

IMO, it is C. But OA says it is A. Please help to explain with proper steps.
Thanks.

Dear Maria,

Let me try to explain the method that I have followed.

According to you,

Selling price = M + Cost (CORRECT)

By statement 1,

M = 25% of the cost.

SP = (Cost/4) + Cost

INSUFFICIENT, as it is a linear equation of two unknown variables.

According to 2nd statement:
SP = $250
and SP = M + Cost (as per our forumula)
Therefore, M + Cost = 250

Again INSUFFICIENT as it is a linear equation of two unknown variables.

Now lets take both statements together.

By statement 1,

SP = (Cost/4) + Cost

and By Statement 2, SP = 250

therefore, 250 = (Cost/4) + Cost

Now its is a linear equation of single unknown variable, hence can be solvable. Therefore SUFFICIENT.

Therefore, correct answer should be (C).

The answer A is correct. The problem with Codesnooker's explanation is that M was replaced by C rather than C replaced by M.

Hope that helps.

I'm definitely NOT an expert, but it's A. We're looking for a percentage/ratio/proportion between the selling price (P) and mark-up (M). In the stem we're given Price= Cost + Mark-Up (P= C + M)

1. M= .25C
Plugging it into the what we were given:
P= C+.25C
P=1.25C and we established that M=.25C. We can stop there because we have a proportion between P & M: P:M= .25:1.25 = 20%

2. Nothing there.

(1) The markup on the television set is 25 percent of the cost.
(2) The selling price of the television set is $250.
We can let c = cost of the article and m = the markup and create the expression:

m/(c + m) x 100 = ?

Statement One Alone:

The markup on the television set is 25 percent of the cost.

From statement one, we have m = 0.25c, and thus our expression now is:

m/(c + m) x 100 = ?

0.25c/(c + 0.25c) x 100 = ?

0.25c/(1.25c) x 100 = ?

0.25/1.25 x 100 = 20%

Statement one alone is sufficient to answer the question.

Statement Two Alone:

The selling price of the television set is $250.

With the information in statement two we can create the following equation:

c + m = 250

With the equation c + m = 250, we can simplify m/(c + m) x 100 as m/250 x 100. However, since we don't know the value of m, we can't determine the value of m/(c + m) x 100. Thus, statement two alone is not sufficient to answer the question.
