Thank you x2suresh - i will take care of the suggestion to not post OA.

Only reason i posted was to save time as my prime concern here was to figure out how to approach the problem in a way which will take minimum time.

As i see in your approach you are taking numbers as examples. But it is not always that simple.

My approach was like this.. which was taking too much time and sort of got unwieldy..

xy - x/y > 0

=> x(y^2) - x > 0

=> x(y -1)(y+1) > 0

=>

4 cases for y and 2 for x

y > 1 / x as +ve or -ve

0 < y < 1 / x as +ve or -ve

-1 < y < 0 / x as +ve or -ve

y < -1 / x as +ve or -ve

--------------------------

Results will be the same if i give it all that time.. but my approach will take too much time to figure out that its inconclusive with given info.

Basically , when will you choose to do it by example only??--------------------------------------------

fiesta - i think you are trying to approach the problem in some reverse order.

Is this what you are trying to conclude?

-- when x > y => we expect something like |y| > 1 to be provided in premises. And its not provided so not sufficient.

-- when x < y => we expect something like |y| < 1 to be provided in premises. And its not provided so not sufficient.

Please clarify, thanks.
