given 2x/y is prime and greater than 2.
=> 2x/y could be any of the following
=> 2x/y is odd and prime (as 2 is the only even prime number and its not in this set)
1. x = y , can't be true
if x=y , 2x/y = 2 which is not odd and prime.
2. y=1. can't be true.
if y=1,2x/y = 2x = even which is not odd & prime.
3. x and y are prime integers, need not be true.
lets say 2x/y = 3 and say y=2 prime
=>x = 6/2 = 3 prime
satisfies the given condition here.
but when 2x/y = 3 and y=5 prime
=> x = 15/2 not prime
My Answer is A.
