i go with AXbond wrote:If x <0, is Y >0 ?
(1) X/Y <0
(2) Y-X >0
I have some problems to define (2) for sure. Can you help me ?
statement 1 X/Y<0
if X<0 for the above equation to hold hold Y has to be >0
hence sufficient
statement 2. Y-X >0
if X< 0 assume it 2 b -4
and y = -1
the it will 3 which is >0
if Y = 3 and X -1 then it will be 4 >0
hence insufficient..
hence A
