Answer E The question says "Can a certain rectangular sheet of glass..." Maybe it looks strange the information in statement (2): "The area of one side of the sheet of glass..." But, the sheet of glass is in fact a 3D object, a rectangular box, probably quite thin. So, we are talking about a rectangular side with the largest area. I don't think they cut the glass at an angle other than 90 degrees. Anyway, the answer is E because the area of 2,400 although greater than 36*60 = 2,160, if the dimensions of the sheet are 30 and 80, it will not cover the tabletop. But if the dimensions are 40 and 60, then yes. The sheet of glass needs to cover the tabletop, not necessarily to be of identical dimensions. In other words, the sheet of glass can be larger than the tabletop, although this isn't practical....

(1) The tabletop is 36 inches wide by 60 inches long. (2) The area of one side of the sheet of glass is 2,400 square inches.
1) nothing can be deduced regarding the dimension of sheet of glass 2) nothing can be deduced regarding the dimension of tabletop combining both statements: by this also the dimension of glass sheet can not be calculated. Hence E

E... Initial i thought A...thinking that the word PARALLEL, but it mean JUST parallel not lying on the same edges

Can a certain rectangular sheet of glass be positioned on a rectangular tabletop so that it covers the entire tabletop and its edges are parallel to the edges of the tabletop? (1) The tabletop is 36 inches wide by 60 inches long. (2) The area of one side of the sheet of glass is 2,400 square inches Question Stem Gives: Rewording is impossible for me on this one. So I'm not even going to try to spend a minute trying to reword. I used the following method. Question Stem provides me with 2 items. Sheet of Glass & Tabletop Statement 1) know 1, but not the other, so Not Sufficient Statement 2) know 1, but not the other, so Not Sufficient Combined: Use extremities. From what the OG guides states, 40x60=2,400, makes sense. Since, I did not reword, I have to prove that the answer 2,400, could be a result of multiple combinations to prove an insufficient answer as a combination. ( this is for most people getting down to a 50/50 split, and guess incorrectly, this is an extra step to eliminate guessing from your answer choices) prove the statement wrong in other words. But what if 2,400=240x10 inches? kind of farfetched, but it proves insufficiency. Correct answer E.

Can a certain rectangular sheet of glass be positioned on a rectangular tabletop so that it covers the entire tabletop and its edges are parallel to the edges of the tabletop?
(1) The tabletop is 36 inches wide by 60 inches long. (2) The area of one side of the sheet of glass is 2,400 square inches.
Ok, I'm a bit confused here.
I see why (1) and (2) alone are insufficient...
However, the maximum area of the table is 2160 while the stated area of the glass is 2400. Even if we were to manipulate the glass perimeter, we could never get it to be 36*60.
The wording is a bit ambiguous when it talks about "parallel to the edges." For example, looking at Bunuel's example, I can understand that the piece of glass may go over the edges of the table but it's edges are still parallel with it. However, the other example used to prove insufficiency was a piece of glass 1*2400. Though slightly hard to visualize, wouldn't the edges still be parallel to the table? Unless of course they are being really obtuse and assuming you could place it at an angle to the table...

Already mentioned in the question " Rectangular glass sheet" One part of the question I understood " that it covers entire tabletop" , to suffice this condition glass sheet must have as same dimensions (length and breadth) as table.

OG 13th ED DS Q32

Should the answer not be C rather than E?
Can a certain rectangular sheet of glass be positioned on a rectangular table top so that it covers the entire tabletop and its edges are parallel to the edges of the table top? 1. The table top is 36 inches wide and 60 inches Long 2. The area of one side of the sheet of glass is 2,400 sq inches.
solution: 1. NS 2. NS 1 + 2: here is my point of contention. The Q asks 'can' which suggest to me 'is it possible' based on info in 1 and 2 it is possible. Sure, it is also not possible but the question does not ask for certainty it only asks for 'possibility'. If the Q was reworded 'Does a certain rectangular sheet of glass, positioned on a table top, cover the entire tabletop with edges parallel to the table top? Then I can see how 1 + 2 together could be insufficient. Perhaps I am over interpreting the question or simply my interpretation is grammatically incorrect.
Your thoughts?

They are both insufficient together, in GMAT whenever they ask you for a possibility they want to know if its possible for sure, so even if there is a possibility with both the set of data, for it to be not possible, then they are insufficient.

Your thoughts? I thought the same. Bunuel, can you comment please? Dear Ergenekon and mpcostelloThe word 'can' in the question is for the verb 'positioned'. Imagine that I handed you an actual glass sheet to put on top of a table. The dimensions of this glass sheet are greater than those of the table. Can I then be sure that the glass sheet IS DEFINITELY going to cover the table top? NO, right? Because whether the glass sheet covers the table or not will also depend on how you position it on the table. Look at the two cases below: In the glass sheet that I gave you in this hypothetical example, there was at least a possibility that the glass sheet could cover the table top. Because the dimensions of this glass sheet were greater than those of the table. So, you could say 'YES, IT CAN cover the table top, though whether it actually does cover it or not depends on how you position it.' Suppose however, I gave you a glass sheet whose length and breadth were much smaller than the length and breadth respectively of the table. Now, if I ask you the same question: 'Can the glass sheet cover the table top?' What will your answer be? 'NO, IT CANNOT' So, if you come to know the dimensions of the glass sheet, you can answer, 'YES IT CAN cover the table top' or 'NO, IT CANNOT cover the table top.' In this question, we were just told that the area of the sheet is 2400 sq. inches. This leads to multiple possible values of (L,B) of the sheet. If say (L,B) are (60,40), then the answer is 'YES, IT CAN cover the table top' but if (L,B) are (80,30) or (2400, 1), then the answer is 'NO, IT CANNOT cover the table top' Thus, we could not find a unique answer to the question because we could not find unique dimensions of the glass sheet. So, the answer is E. Hope this helped clarify your doubt! Best Regards Japinder
