ds yes no answer question from princeton review ds drill 11
--------------------------------------------------------------------------------
If x is a positive number, is x < 1?
(1) 2x < 1
(2) 2x £ 2
its answer is A
its gives yes when we plug values less than 1/2 but what if we plug values like 4/5 which is .8 or 3/5 which is .6 it gives no answer so princeton review called statement 1 sufficient despite of the fact it gives sometime positive and sometime negative value.
somebody put more light on it how is that possible ?
