Fractions are the best bet for this problem since it says x/y are positive but not positive integers
Stmt I
x=9 y=2
sqrt(9) = 3 > 2 and x^3>y YES
x=1/4 y=1/3
sqrt(x) > 1/3 but x>y NO
insuff
Stmt II
3 > 2
3^3>y YES
1/2 > 1/3
1/2^3 > 1/3 NO
INSUFF
Stmt I and II together
x=9 y=2
sqrt(9) > 2 and 9>2 and 9^3 > 2 YES
x=1/4 y=1/5
x>y and sqrt(x) > y but IS x^3 = 1/4^3 > 1/5 -> NO

bacali next time you see problem like this in which:bacali wrote:OA E
1) x and y are positive
2) and X and Y have no numbers preceding them
Make sure that you use:
An integer that is greater than 1
An integer that is between 0 and 1: choose 1/2
because between 0 and 1 math and numbers act crazy!
