UPSC NDA Math Model Paper 8

Given, A=[

3	4
5	6
7	8

] and B=[

3	5	7
4	6	8

]
⇒ Order of matrix A = 3 × 2 and Order of matrix B = 2 × 3 We can find inverse or adjoint of square matrix only.
Here, Matrix A and B are not square matrix.
Transpose of matrix A is obtained by interchanging rows and columns of matrix.
Here B is the matrix which is obtained by interchanging rows and columns of matrix A.
So, B is the transpose of A.
