If A and B are two matrices of order 2 × 2 such that A is a symmetric matrix and B is a skew-symmetric matrix, then:

Let $A$ be a non singular matrix of order $n \times n$, Then $|\text{adj }(3A)|$ is equal to:

The value(s) of $k$, for which the system of linear equations $2x + y + z = 1, 2x + 3y + 4z = 3, x - y + kz = 5$ does not possess a unique solution is
