If the value of p is one of the numbers 2 and 3 then is pq not=6 ?
1. If p equals 2 , then q equals 3
2. If q equals 3 , then p equals 2
1. If p equals 2 , then q equals 3
2. If q equals 3 , then p equals 2
With all the "if's", its a tricky question.
IMO (E)
P = 2 or 3
pq not=6? You are looking for a definite YES/NO answer
(1) if p=2,q=3 but what if doesent = 2. If p=3, then whats q? If q=2, then pq=6, if q not=2, then pq not =6
insuff.
(2)
if q=3,p=2, again what if q not=3. then whats p?
insuff.
together:
again the "if's" lead to many possibilities.
if p=2,q=3
if q=3,p=2
what if p=3, whats q?
insuff.
hence IMO (E)
What is the source of this question?
