A. 52 B. 53 C. 54 D. 55 E. 56
Total = Stockholders + Employees - Both; 100 = 62 + 47 - Both --> Both = 9;
Percent of stockholders, who were not employees is: Stockholders - Both = 62 - 9 =53.

Here we can use some of our high school set theory => N(A U B) = 100=> N(A) = 62 ; N(B)=47 N(intersection) => 62+47-100=9 Only A=>62-9=>53 Smash B _________________

I too used the Double Matrix Approach to solve this.
The Key thing here is to pay attention to - "Each person who attended a company meeting was either a stockholder in the company, an employee of the company or both.".
What this means is there is no one in the Meeting who is neither a Shareholder NOR an employee.
Once this is know the double Matrix can be written quickly. This is already mentioned by one of the users above. _________________

OK, still figuring out how I could solve this. I came across a video tut on here to solve questions using double matrix method. In that context, susheel - did you mean NEITHER a stockholder NOR an employee?
GMATPrepNow - Could you help me with the double matrix table as you explained in one of your videos, please?
Yes, thats correct! I will go and edit the typo. Thanks for pointing it out
Here's the double Matrix. Just to make it clearer.

We choose 100 as the smart number since everything is in percentage (Its marked in Orange in the screen shot). The Green colour is what is "Given"in the question. Rest everything is simple addition. Finally we get the required answered (Marked in Yellow).

Thank you, susheelh. Job well done at explaining! I intend to follow this approach for overlapping sets ... although, I am yet to encounter a problem where there are more than 2 sets that overlap.

I was thinking about the same as well. Like I said, I have not yet started working on Overlapping Sets questions just yet to evaluate the two approaches Thanks, bud!

A. 52 B. 53 C. 54 D. 55 E. 56
We can use the equation:
Total = Stockholders + Employees - Both + Neither
100 = 62 + 47 - Both + 0
100 = 109 - Both
Both = 9
Thus, the percent of people at the meeting who were stockholders but not employees (i.e., stockholders only) is 62 - 9 = 53 percent.

I am a bit confused. I saw this question in the quant review after number 60 i think, so i was under the impression that it would be atleast above 600 level but i dont see thats the case. reason to ask is that i am not too comfortable solving such questions, can someone comment on the difficulty level of this question ?

Let's use the Double Matrix Method. This technique can be used for most questions featuring a population in which each member has two characteristics associated with it (aka overlapping sets questions).
Here, we have a population of attendees, and the two characteristics are: - stockholder or not a stockholder - employee or not an employee
Since we're not told the total number of attendees, and since we're trying to find a PERCENTAGE, let's assign a nice value to the total number of attendees Let's say there are 100 attendees
Finally, since we're looking for the percentage of attendees who were stockholders but NOT employees, let's place a red star in that box to remind us of what we're trying to determine.
62 percent of those who attended the meeting were stockholders This also means that the other 38 percent are NOT stockholders
47 percent were employees This also means that the other 53 percent are NOT employees
At this point, we appear to have no more information to add to our diagram. However, we also know that each person who attended a company meeting was either a stockholder in the company, an employee of the company, or both This means that there were ZERO people who were neither a stockholder nor an employee. So, we can add this to our diagram.
Since the two boxes in the right-hand column must add to 53, we know that the top right box must have 53 people in it...
What percent were stockholders who were not employees? Out of 100 attendees, 53 people were stockholders but not employees In other words, 53% of the people were stockholders but not employees
Answer: D Aside: We can also use Venn diagrams and formulae to solve overlapping sets questions. However, as difficulty levels increase, it becomes harder to apply those other approaches, whereas the Double Matrix Method works every time.
This question type is VERY COMMON on the GMAT, so be sure to master the technique.
