We can get one set of relation among the three when x is a positive integer > 1

However when we take a value of x between 0 and 1 then we will get a different relation among the three.

Hence we can never determine the relationship.

Hence ans None.

Answer is It could be I or II

Understand this is a could be question not a must be one

X= 0.1 then X^2<2X<1/X , is satisfied so I is OK

X = 0.9 then X^2 < 1/X < 2X is satisfied so II is OK

Absolutely.. answ shud be D

Statement I is valid for all 1/sqrt(2) > x > 0

Statement II is valid for all 1/sqrt(2) < x < 1
