I remember solving this before
For problems like this consider fractions and integers. When considering fractions pick extreme values(we know in this porblem its all positive)
x=1/10 x=9/10
For x=9/10 II will be true
Easy way to eliminate III would be
2x<x^2<1/x
Divide inequality by x(inequality does not change since x is positive)
2<x<1/x^2
Can we find any value for x>2 where 1/x^2>x ->NO
Hope this helps!
