can somebody please explain this.Looks a very easy question but i am confused about the OE given.

Is x > y?

(1) x^2 > y

(2) x – |y| > 0

Statement 1 is clearly not sufficient alone. Only if we know that x > x^2, will we get a definite answer. But x > x^2 only when x lies between 0 and 1 which is not given. So statement 1 is not sufficient.

Statement 2 tells you that x > |y|. This means x is greater than the absolute value of y. Then x has to be greater than y too.

Think about it: |y| is either equal to y (when y is +ve or 0) or it is greater than y (when y is negative). So if x is greater than |y|, it has to be greater than y too.

You can also take an example to understand this.

Say y = -4

Given x > |y| i.e. x > 4

Then x has to be greater than -4 too.

Say y = 4

Given x > |y| i.e. x > 4

In either case, x has to be greater than y.

So statement 2 alone is sufficient.
