The determination of the matrix (begin{pmatrix} 1 & 3 & 3 \ 4 & 5 & 6\ 2 & 0 & 1 end{pmatrix}) is

A.
67 
B.
57 
C.
3 
D.
3
Correct Answer: Option D
Explanation
4 x 2 = 8 upward arrows = +ve
2 x 5 x 3 = 30
0 x 6 = (frac{0}{22}) downward arrows = ve
1(1 x 5x – 1) = 5 – (2 x 6 x 2) = 24
= (4 x 0 x 1)
= (frac{0}{19})
therefore 22 – 19 = 3
