If p+5/q is a prime integer, which of the following must be true?
1.q=5p
2.q is a prime integer
3. p+5/q is ODD.  Select the correct option
A) None
B) 1 only
C) 2 only
D) 1 and 2 only
E) 2 and 3 only.
I would pick up numbers and do .   i hope the question is (p+5)/q....   let p = 3 , q = 4   3+5/4 = 2 = Prime   1. q is not equal to 5p   2.q is not a prime number   3. (p+5)/q is not odd.   hence None
