If integer p is greater than 1, is p a prime number?
(1) p is odd.
(2) The only positive factors of p are 1 and p.
Given p>1 and p is an integer.
Question stem:- Is p a prime number
Statement-1:- p is odd
So, P=3,5,7,9,11,13,15..etc.
P is prime when p=3,5,7,11 etc and p is not prime when p=9,15 etc.
hence insufficient.
Statement-2:- The only positive factors of p are 1 and p.
It implies that p is a prime number.
Hence, sufficient.
Ans. (B)
