MCQ
Suppose $X =\left[x_{i j}\right]$ a matrix, where
$
X=\left[\begin{array}{ccc}
1 & -1 & 2 \\
3 & 4 & -5 \\
2 & -1 & 3
\end{array}\right]
$
Then matrix $Y =\left[m_{i j}\right]$, where $m_{i j}=$ minor of $x_{i j}$ :
$
X=\left[\begin{array}{ccc}
1 & -1 & 2 \\
3 & 4 & -5 \\
2 & -1 & 3
\end{array}\right]
$
Then matrix $Y =\left[m_{i j}\right]$, where $m_{i j}=$ minor of $x_{i j}$ :
- A$\left[\begin{array}{ccc}7 & -5 & -3 \\ 19 & 1 & -11 \\ -11 & 1 & 7\end{array}\right]$
- B$\left[\begin{array}{ccc}7 & -19 & -11 \\ 5 & -1 & -1 \\ 3 & 11 & 7\end{array}\right]$
- C$\left[\begin{array}{ccc}7 & 19 & -11 \\ -3 & 11 & 7 \\ -5 & -1 & -1\end{array}\right]$
- ✓$\left[\begin{array}{ccc}7 & 19 & -11 \\ -1 & -1 & 1 \\ -3 & -11 & 7\end{array}\right]$
