This is an MCQ-based quiz on Matrices.

This includes Types of matrices, Operations on Matrices, and Transpose of a Matrix.

For any unit matrix I

A matrix A = [aij]m×n is said to be symmetric if

A matrix A = [aij]m×n is said to be skew symmetric if

If A and B are square matrices then (AB)’ =

A = [aij]m×n is a square matrix if

M = N

M < N

M > N

None of these

The number of all possible matrices of order 3 × 3 with each entry 0 or 1 is

If A, B are symmetric matrices of same order, then AB – BA is a

Matrices A and B will be inverse of each other only if:

If a matrix is both symmetric and skew- symmetric matrix, then:

If A is a square matrix such that A² = A, then (I + A)³ – 7A is equal to :

If a matrix is both symmetric matrix and skew symmetric matrix then

If A is a square matrix such that A² = I, then (A – I)³ + (A + I)³ – 7A is equal to

For any two matrices A and B, we have

A square matrix A = [aij]n×n is called a diagonal matrix if aij = 0 for

M × 3

3 × 3

M × N

3 × N
