Is P > |Q| ?
(1) P^2 > Q^3
(2) P > Q
Breaking Down the Info:One thing to note is if we know P was negative, we can say the statement(s) is sufficient since |Q| has to be nonnegative.
Statement 1 Alone:If both P and Q are positive, we may have P > Q = |Q|. If P is negative and Q is positive, then P < |Q|. Since we have both cases, this statement is insufficient.
Statement 2 Alone:Q might be a huge negative number, resulting in |Q| > P. Thus this statement is insufficient.
Both Statements Combined:If both P and Q are negative, we would have P < |Q|. If both P and Q are positive, we would have P > Q = |Q| (check that statement 1 does not interfere with these cases). Since we have both cases, combined it is insufficient.
