Let A = \left( {\begin{array}{*{20}{c}}  { - 1}&2&{ - 3} \\   { - 2}&0&3 \\   3&{ - 3}&1 \end{array}} \right) be a matrix, then ) is equal to

  1. \left( {\begin{array}{*{20}{c}} { - 1}&2&{ - 3} \\ { - 2}&0&3 \\ 3&{ - 3}&1 \end{array}} \right)

  2. \left( {\begin{array}{*{20}{c}}
    3&{ - 3}&1 \\
    3&0&{ - 2} \\
    { - 1}&2&{ - 3}
    \end{array}} \right)
Correct Answer: Option(c)
Solution:
Solution -
We know that 

and


adj(A^{-1})\times det (A)= A= \left( {\begin{array}{*{20}{c}}  { - 1}&2&{ - 3} \\   { - 2}&0&3 \\   3&{ - 3}&1 \end{array}} \right)

C is correct
