For a non singular matrix A of order n the rank of A is (A) less than n (B) equal to n (C) greater than n (D) none of these

If A is non singular matrix of order 3 , then the rank of A =

If A is non-singular matrix of order 3 ,then the rank of A=

If A is a non-singular matrix of order n, then A(adj A)=

If A is a singular matrix of order n, then (adjA) is

If A is a singular matrix of order n, then A(adjA)=

If A is a non-singlular square matrix of order n, then the rank of A is

Let A be an orthogonal non-singular matrix of order n, then |A-I_n| is equal to :

"If B is a non -singular square matrix of order 3 such that |B|=1 then "det (B^-1) "is equal to (a) 1 (b) 0 (c)-1 (d) none of these"

If A is a non singular matrix of order 3 then |adj(adjA)| equals (A) |A|^4 (B) |A|^6 (C) |A|^3 (D) none of these
