* A solution will be posted in two days.

Question : Is |x|/x equals to 1.

or Is |x| = x, which is possible when x > 0, so we need to find out whether x > 0 or not.

St 1: x > 0 (Sufficient)

St 2: x < 1

Take x = 0.5, then Is |0.5|/0.5 = 0.5/0.5 = 1

But if x = -1, then 1/-1 not equal to 1

Therefore, Not sufficient

(A)
