Quick approach. a>0? stmt1, a^3 - a < 0 a=0.5,a^3-a<0--> a>0 a=-2,a^3-a<0-->a<0 Not suff stmt2, 1 - a^2 > 0 a=-0.5,1 - a^2 > 0 -->a<0 a=0.5,1 - a^2 > 0 -->a>0 Not suff Combining 1 and 2, 1 - a^2 > 0 or a^2-1<0 a^3 - a < 0 -->a(a^2-1)<0 We know that a^2-1<0.So a must be greater than zero so that the ...

Z^n=1

z=?

stmt1,

n is a non zero number.

Z=1,n=1,Z^n=1

Z=-1,n=2,Z^n=1

Insuff

stmt2,

Z>0

Z=2,n=0,Z^n=1

Z=1,n=1,Z^n=1

Insuff

Combining 1 and 2,

Z>0 and n is non zero number.

-->Z=1

Suff

Pick C

Only when x=4.

x-4=4-x

x-4=-(x-4)

2(x-4)=0

x=4


Hope this clarify!!
