							Dear SUMIT,

Hope doing well in your studies. 


RANK OF A MATRIX :  The rank of a matrix is the maximum number of independent rows (or, the maximum number of independent columns). 

For Example   1 2 0 3
              1 7 3 0
              0 0 4 8
              2 4 0 6

Start with row 1: See if row 2, 3 or 4 are multiples. If so, cross that out.
Go to row 2: See if row 3 or 4 are multiples...
Finally compare row 3 and 4.

This is for 4 rows, but you can extend this to n rows. Similarlly go for Columns as well.

All the Best Sumit!!!
