Hi guys:
I constantly get inequality questions in DS wrong. Particularly the ones which ask whether one side is greater or lesser than the other.
Eg:
Is x < y
(a) 2x < 3y
(b) xy > 0
Is 1/(a-b) < b-a
(a) a < b
(b) 1 < |a-b|
I try to approach them algebraically and do not get conclusive answers and by the time I start plugging-in the clocks start ticking ...
Just wanted to know how people approach these questions.
Thanks.
