acc to GMATTIGER'S link the 4th option is I and II, so there is deifinitely typo error. Now can u pls explain ur choice?In such cases how shld one chose nos?
krishan, can you revise the answer choices for typo?
I get I and II, but there is no such choice.
to make it easy.. multiple with x throug all options
I x^2 < 2x < 1/x
--> x^3<2x^2 <1
substitiute x=1/2 1/8<1/2<1
could be the answer choice.
II. x^2 < 1/x <2x
--> x^3 <1 <2x^2
here assume value such that 2x^2>1 ..
X= 1/sqrt(2) 2x^2=1
above equation could be answer when x<1 and x>1/sqrt(2)
III. 2x < x^2 < 1/x
-->2x^2 <x^3 <1
