What is the volume that a certain jar can hold?
(1) The jar currently holds 5 cups of soup.
(2) If 2 cups of soup are added to the jar when it is already \(\frac{1}{3}\) full of soup, the volume of soup in the jar will double.

I feel this is not a completely correct question, since one can only answer the volume in cups in this question, and not the actual volume of the jar. also, the first stem sounds ambigious - it's either the jar is fully filled with 5 cups, or it currently contains 5 cups, but we don't know if it is full of not. Please correct me if I am wrong.
(1) 5 cups
NOT SUFFICIENT since we don't know the volume of each cup
(2)
Total volume = V
Volume of a cup = C
\(\frac{1}{3}V + 2C = 2V\)
NOT SUFFICIENT since we don't know the volume of the cup
1, 2) Assuming one jar is filled with 5 cups
V = 5C
\(\frac{1}{3}5C + 2C = 10C\)
Stems contradict themselves (?)

Kaplan's Official Solution:
CORRECT ANSWER IS B.
Statement (1): insufficient. This tells us that the jar can hold at least 5 cups, but it doesn't tell us its maximum capacity. Eliminate choices (A) and (D).
Statement (2): sufficient. If adding 2 cups of soup doubles the volume, then there were already 2 cups of soup in the jar. So 2 cups =\(\frac{1}{3}\) of the volume of the jar, and the total volume that the jar can hold is 2 × 3 = 6 cups. Therefore choice (B) is correct.
