If u+5/v is a prime integer, which of the following must be true?
1.v=5u
2. v is a prime integer
3. u+5/v is ODD. Options:
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 (u+5)/v....   let u = 3 , v = 4   3+5/4 = 2 = Prime   1. v is not equal to 5u   2.v is not a prime number   3. (u+5)/v is not odd.   hence None
