1. Q is not equal to 1
2. P is positive

What all can be the values of P and Q..
P is 16 and Q =1...
P is 4, Q =2
P is -4, Q is 2
P is 2 and Q is 4
P is -2 and Q is 4

Let's see the statements
1) Q is not EQUAL to 1
There are four other cases..
|4-2|=2..
|-4-2|=6
Insufficient
2)p is positive
|4-2|=2
|16-1|=15
Insufficient

Combined
Only two cases
|4-2|=2
|2-4|=2
Ans is always 2
Sufficient
