Thank you for using the timer!
We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:
1. If P^Q = 1 then P = 1 or Q = 0. consider p = 2 then Q has to be 0. P = 1 then Q can be anything. not suff. 2. Q= -1 then P and can be possibtive and PQ<1 or P can be negative ans PO>1. hence not suff.
combining 1 and 2.
if Q= -1 then P has to be 1 hence PQ <1 suff. answer should be C _________________
