(1) n² > 16 implies n > 4 or n < -4.jainrahul1985 wrote:If n is not equal to 0, is |n| < 4 ?
(1) n^2 > 16
(2) 1/|n| > n
OA A
If n > 4, then |n| > 4
If n < -4, then |n| > 4
From both the cases, we get the same answer; SUFFICIENT.
(2) 1/|n| > n
If n = -6, then 1/6 > -4. Here, |n| = 6 > 4
If n = -1, then 1/1 > -4. Here |n| = 1 < 4
From the above examples, it can be seen that we do not get a definite answer; NOT sufficient.
The correct answer is A.
