Its really strange how did you assume something as there may be other possibility.
I read you explanation, sir! But I didn't get how assumption is applicable in quant section.
In my opinion, what if only B is 2 and Only S is 1, then I would get 2 as answer. Or B and S can have 1 and 2 respectively.
Q asks number of people who don't like to play any of the 3 games. Means number of students completely outside of shown circles.
Please explain.

Out of the 14 people in a group, 3 like to play Badminton, Soccer and Volleyball. If there are 7 people in the group who like to play Volleyball and 5 who like to play Badminton and Soccer, what is the number of people who do not like to play any of the 3 games?
A. 2
B. 5
C. 6
D. 7
E. Cannot be determined
We can draw the circles as shown..
All three games = 3.
So only B+S=5-3=2
V+(any one game only or none)=7-3=4
Total who play game=3+2+4=9.
So, the number of people who do not like to play any of the 3 games = 14-9=5.
B
Hi
Yes, we are not supposed to assume anything, and nothing has been assumed. If you say there is something more than what is given, then you are assuming.
The details you are looking at is important for DS question. Because traps lie in these kind of lines. They give you that there are 2 red balls and 2 white balls and we are looking at the probability of picking red. Of course we would require to know the total balls or that no other colour is present.
But if in a PS question, I give you that there are 2 red balls and 2 white balls, and you have to find the same probability. Will you say that it cannot be determined because there can be other colours too. No, you cannot as you have to work on data given.
Same is the case here. If some data is given, why should I take that the data is inadequate if there is nothing in the question stem that tells me that there have to be some playing soccer alone ?
But if it were DS and I had this data , I would mark E the same way as I would do it for red and white balls example.
Finally, as I have written, you will not find such wordings in GMAT.
