1) if x = 3, y =2. 2x is divisible by y but x/y is not an integer.
if x = 6, y =2. 2x is divisible by y but x/y is an integer.
Hence NOT SUFFICIENT
2) x/2y = Integer, Hence x/y = 2*Integer = integer
SUFFICIENT

If x and y are positive numbers, is x/y an integer?
1) 2x is divisible by y
2) x is divisible by 2y
A) 2x is divisible by y
1)If X=0.1 and Y=0.2, then X/Y is integer.
2)If X=9, Y=2, then X/Y = 4.5 which is not an integer.
B) X is divisible by 2y.
If X is divisible by 2y, then X/Y is always integer. Option B is sufficient.
