P.s: what does "mode" means?

The value that appears most within a set of numbers.
For example, the mode of the set consisting of the numbers 2, 4, 3, 2, 8, 2 is 2 since the number two appears the most (i.e., three times).

(1) 0 and 1 appears twice in [3, 0, 1, - 1, 0, 5, 1] so it has two modes 0 and 1 .thus insufficient
(2) if no is neither positive nor negative .Its definitely 0. Thus sufficient

OA should be B

Mode of a set is the number that appears most frequently.

From (1), N = 1 or 0, so not sufficient.

From (2), N = 0, so sufficient as 0 is niether -ve nor +ve.

Hence the answer is B.

Statement 1 has both 0 and 1 occurring twice. Inufficient

Statement 2

Firstly, forget that you have read statement 1. Now, analysing statement 2, N is neither positive or negative. In the entire universe that is not governed by Christopher Nolan's Interstellar physics, there is only one number that is neither negative nor positive i.e. 0.

Hence, statement 2 alone is sufficient.

B
