51.	If A is a matrix of order m x n and B is a matrix such that AB' and B'A are both defined, the order of the matrix B is (1) n x n (2) m x n (3) m x m (4) n x m
Answer» Correct option (2) m x n Explanation: A = m x n, B = p x v AB' = ( m x n) x (q x p) ⇒ q = n B' A = (q x p) x ( m x n ) ⇒ p = m

51.

If A is a matrix of order m x n and B is a matrix such that AB' and B'A are both defined, the order of the matrix B is (1) n x n (2) m x n (3) m x m (4) n x m

Answer»

Correct option (2) m x n

Explanation:

A = m x n, B = p x v

AB' = ( m x n) x (q x p) ⇒ q = n

B' A = (q x p) x ( m x n ) ⇒ p = m
