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.

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.

if we put in numbers it becomes easy !! and A it is.

cost : 100 markup : 25% : 25 sp: 125

now as per the question : 25= x/100*125 =20%

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.

Guys OA is correct it has to be A.
Let x is cost of tv, markup will be 0.25 x
S.P.= 1.25 x
required info= .25 x/1.25x(100)= 20 %

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).
