If `n=p`, then the order of the matrix `7X-5Z`is:(A) `p xx2` (B) `2xx n` (C) `n xx3` (D) `p xxn`

Assume X, Y, Z, W and P Are Matrices of Order 2 x n, 3 x k, 2 x p,N x 3 and Respectively. If n =p , then the order of the matrix 7X-5Z is : (A) pxx2 (B) 2xxn (C ) nxx3 (D) pxxn

If n=p, then the order of the matrix 7X (D) p xx n

If A and B are two matrices of the order 3 xx m and 3 xx n , respectively and m= n, then order of matrix (5A-2B) is (a) m xx 3 (b) 3 xx 3 (c) m xx n (d) 3 xx n

If A and B are two matrices of the order 3 xx m and 3 xx n , respectively and m= n, then order of matrix (5A-2B) is (a) m xx 3 (b) 3 xx 3 (c) m xx n (d) 3 xx n

If A is a matrix of order m xx n and B is a matrix such that AB^(T) and B^(T)A are both defined,then the order of matrix B is m xx n (b) n xx n( c) n xx m(d)m xx n

If A and Bare two matrices of the order3xx m and 3xx n, respectively and m=n, then order of matrix (5A-2B) is (a) m xx3 (b) 3xx3( c) m xx n( d )3xx n
