(1) x = y^3 and n > y.
(2) x > 5y and n > x.


B
1. (x/y)^n = (y^3/y)^n= y^2n. we can get values both greater or less than 1000 hence insuff
2. x>5y so if y =1 then least value of x is 6 and n>x>6. ie minimum value we will get is 6^7. hence suff

Also getting B

1) let's assume y = 1 then x = 1 and doesn't matter what n is it will be less than 1000
y = 2 x = 8 n can be anything that makes it >1000
insufficient
