dear prateek  ,

determinany of inverse = 1/determinant)n-1

n is the order of matrix

determinant of inverse of matrix with determinat value 6 is 1/36 ...

 

this resullt can be proved by taking  example of any matrix ....

so if u want to derive this result then take a example of simple matrix & prove....

 

approve if u like my ans
