In the graph shown above, which sector represents the $9.6 million budgeted by Company X for radio marketing?

Notice that we are told that the figure is drawn to scale, thus:
A is less than 25%;
B is greater than 25%;
C = D = 25/2=12%;
E = 25%.

(1) Sector E represents 25% of the total annual marketing budget for company X. We knew this from the stem. Not sufficient.

(2) The total annual marketing budget for company X was $48 million. 9.6 is 20% of 48, thus A must be it. Sufficient.

Answer: B.

HI Bunuel,

I have 2 doubts on this question ,,
1)it is said in the figure that the figure is not drawn to scale, then how can it be concluded that the E=25 % ,, what if it is some more or less than that
2) the question asks which sector has $9.6 million budgeted. Does it ask for 9.6 exactly or at least the specified amount. If it asks at least then even B could be the answer.

when you say B is sufficient, is the sector A or E??

I really went with E on this.

1. We are told that the figure IS drawn to scale.
2. Yes, we are asked to find which sector represents exactly $9.6 million. Only A can be it.

thanks Bunuel ,, not sure why I read it "not drawn to scale"

I have notices that the graph is drawn to scale, but still didnt get from where we got that 25%
p.s. sorry for the stupid question, but I really dont know why 25% . do we have 25% ,since we just divide 100 to 4 major slices (a, b, c, and d+e) ?

E is 25% because it's 1/4th of the circle.

Am I the only one who thinks this is a poor question by GMAC? I mean to rely on visual inspection for the right answer is quite subjective, aint it? Has anyone seen another such question from GMAC?

Thanks Bunuel. Will take a look at them.

I too think this is not a good question. I mean come on, E could be anywhere between 24% to 26%. If it was written that it is not drawn to scale, we would have definitely given the 24% to 26% range some serious thinking...?

It is given that graph is drawn to scale and E represents 1/4 of the graph,

C and D combined represents 1/4 of the data and since each one is equally spaced so C=D=1/8.

B is bit larger than E and A is smaller than E .


1. Statement 1: No information given about the budget. Won't be able to deduce which one represents $9.6 million.

2. Total budget = 48

so 9.6/48=1/5; from the given fact A = 9.6

So option B

The graph provides information about the MARKETING BUDGET

The question stem asks about RADIO MARKETING BUDGET

Radio marketing CAN BE A SUB-GROUP of total marketing.

None of the choices provides information about RADIO MARKETING.

Why isn't the answer E

In the graph shown above, which sector represents the $9.6 million budgeted by Company X for radio marketing?

Radio marketing IS a part of the Annual Marketing Budget. How else?

We know that radio marketing = $9.6 million

From (2) we know that 9.6 = 20% of 48 and again from the stem, we know that sector A = ~20%. Thus, sector A (20% of the circle) represents the $9.6 million (20% of 48 million) for radio marketing.
_________________

what i did for statement two was 9.6/48*360 = 72 degrees
since the pie chart was drawn to scale, b & e > 90 degrees
left with A, C, D. if either c or D = 72 then c + d = 144 (which doesnt make sense as c + d + a would be 288 and resulting in b & e each lesser than A.)

Hence A is the portion that represents 9.6$m

Bunuel
in your post "Notice that we are told that the figure is drawn to scale, thus:
A is less than 25%;
B is greater than 25%;
C = D = 25/2=12%;
E = 25%. "

C=D= should be 12.5% .
please check.
thanks.
