statement 1 :jainrahul1985 wrote:Is |x|< 1?
(1) |x + 1| = 2|x - 1|
(2) |x - 3| ≠0
Ans. C
after squaring both the sides and simplification, we get :
(x-1/3)(x-3) = 0 OR x = 1/3 or 3
hence, the statement is not sufficient.
Statement 2 says :
x ≠3 , hence not sufficient.
Combining :
we get, x =1/3 , which is sufficient to tell the answer.
Hence, C
