Example text

From here on, it’s AD or BCE. What this means is that if statement (1) is sufficient, then the answer to the question will be either A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient. or D. EACH statement ALONE is sufficient. If statement (1) is sufficient, then A and D are the only possible answers. You can cross the others off your list right now. On the other hand, if statement (1) is not sufficient, then the answer cannot be A or D. Now, let’s consider the question given.

The answer is D. You don’t know what the actual dimensions of the first barrel are, but you know that the volume of a cylinder = πr2h (r = radius and h = height), and in the case of the first barrel, πr 2h = 100 gallons. You don’t know the exact dimensions of the second barrel either, but you know that its height is twice that of the first barrel, so 2h, and its diameter is twice that of the first barrel, and since the diameter of a circle is double the radius, it follows that the radius of the second barrel must be twice that of the first barrel as well, so 2r.

Sometimes, even when the answers try to be treacherous and deceitful, they wind up being our friends anyway.
