Statement 1: x<0 Hence the value for x would be -1,-2,-3.... $$\frac{|-1|}{-1}$$ = $$\frac{1}{-1}$$ = -1 Similary $$\frac{|-2|}{-2}$$ = $$\frac{2}{-2}$$ = -1 So for all values of x<0 it is -1. Sufficient Statement 2: x=-1 Value of x given directly (same calculation as made in statement 1). Sufficient. Hence D. _________________ Never stop dreaming...!!!

Thus, if x<0, you get |x|/x=-x/x=-1, so con 1) = con 2), and therefore the answer is D.

Given x≠0

Question: |x|/x=?

St 1 : x < 0

means x is negative number

Take any number say x = -2, we get |-2|/2=-1

Take x = -1/4, we get |-1/4|/-1/4= - 1......Sufficient

St 2 : x = -1.....Sufficient

(D)

If x≠0, |x|/x=?

1) x<0
So,|x|/x=-x/x=-1
Suff.

2) x=-1
So,|x|=1 (absolute value is positive)
|x|/x=1/-1=-1
Suff.
