Data Sufficiency :: RE: Is X^3>y^2

Author: thephoenix Posted: Fri Mar 12, 2010 12:33 am (GMT -8) Is X^3> y^2—–> x and y can be a int or fraction and for bth the cases we get two possibilities provided we know that how x is related to y so our task is to find realtion b/n x and y and whether x and y are int or fraction???? if know the ans to abve we can solve it 1). y=x^2 —-> x^3> x^4(substituting y in original) if x is int then no equality does not holds true and if x is a fraction then yes it holds true two possibilities hence insuff…

You’ve fallen into a common trap here: The equation in the question is not an equation that is given as true. Instead, it is an equation whose truth the question is asking you to evaluate
