Matrix and Determinants

If the order of matrix A is m×p and the order of matrix B is p×n. Then the order of matrix AB is

• m × n

• n × m

• n × p

• m × p

When you multiply a matrix by the inverse matrix, you obtain the

• inverse matrix.

• transpose matrix.

• Identity matrix

• Identity matrix

Two matrices A and B are multiplied to get AB if

• both are rectangular both have same order

• no of columns of A is equal to columns of B

• no of rows of A is equal to no of columns of B

• no of columns of A is equal to no of rows of B

If |A| = 0, then A is

• zero matrix

• singular matrix

• non-singular matrix

• Identity matrix

which of the following is correct

• determinants is a square matrix

• determinants is a number associated to a matrix

• determinants is a number associated to a square matrix

• none of these
