Target question: Is k greater than t?
When I SCAN the two statements, they both feel insufficient, AND I’m pretty sure I can identify some cases with conflicting answers to the
target question. So, I’m going to head straight to……
Statements 1 and 2 combined
There are several values of k and t that satisfy BOTH statements. Here are two:
Case a: k = 24 and t = 1. In this case, the answer to the target question is
YES, k is greater than t
Case b: k = -24 and t = -1. In this case, the answer to the target question is
NO, k is not greater than t
Since we can't answer the
target question with certainty, the combined statements are NOT SUFFICIENT
Answer: E
