Question: Is wt of water > weight of X for smae volume?
Statement 1: A cubic unit of water weighs more than 1/3 cubic unit of liquid X.
If 1 cubic unit of water is heavier than 1/3 cubic unit of other then we can NOT be conclusive of comparison
NOT SUFFICIENT
Statement 2: A cubic unit of liquid X weighs less than 3 cubic units of water.
dividing both sides by 3
If 1 cubic unit of water is heavier than 1/3 cubic unit of other then we can NOT be conclusive of comparison
NOT SUFFICIENT
Combinig the statements
Both statements have same information hence
If 1 cubic unit of water is heavier than 1/3 cubic unit of other then we can NOT be conclusive of comparison
NOT SUFFICIENT
Answer: Option E

By statement 1, A cubic unit of water weighs > 1/3 cubic unit of liquid X
=> 3 cubic unit of water weighs > 1 cubic unit of liquid X
But we don't know whether a cubic unit of water is more or less than a cubic unit of liquid X.
Hence, statement 1 alone is insufficient.
By statement 2, 3 cubic unit of water weighs > 1 cubic unit of liquid X
This is same as we got in statement 1 , hence statement 2 alone is also insufficient.
Also, as both statements are same we can't answer by combining both.
Thus OA is E
