Is X ^ 2>-X?
(1) X <1

(2) X> -1


Statement 1: if X = -1, 1 > 1 not true

if x = -2 , then 4 > 2 which is true so insuffi.

Statement2: X>-1
if x=1, 1 > -1 true

x = -1/2 so 1/4 > 1/2 not true..so insufficient

Taking both statement together,
X<1 and X >-1

x = -1/2 so 1/4 > 1/2
X = 1/2 so 1/4 > -1/2

So not sufficient.

Answer : E
