Statement 1:VJesus12 wrote:Is i>j?
1) k²j > ki
2) j²k > ji
Case 1: k=1, j=2 and i=1, with the result that k²j=2 and ki=1
In this case, i < j, so the answer to the question stem is NO.
Case 2: k=-1, j=-2 and i=3, with the result that k²j=-2 and ki=-3
In this case, i > j, so the answer to the question stem is YES.
Since the answer is NO in Case 1 but YES in Case 2, INSUFFICIENT.
Statement 2:
Case 1: k=1, j=2 and i=1, with the result that j²k=4 and ji=2
In this case, i < j, so the answer to the question stem is NO.
Case 2: k=-1, j=-2 and i=3, with the result that j²k=-4 and ji=-6
In this case, i > j, so the answer to the question stem is YES.
Since the answer is NO in Case 1 but YES in Case 2, INSUFFICIENT.
Statements combined:
Cases 1 and 2 satisfy both statements.
Since the answer is NO in Case 1 but YES in Case 2, INSUFFICIENT.
The correct answer is E.
