Let,
the numbers be "x" and "y"
According to the question,
x = 4y ......................................................equation (1)
...................................equation (2)
Taking equation (2)
Substituting the value of "x" from equation (1), we get,
Cross multiplying, we get,
<u />
Now,
Taking equation (1)
x = 4y
Substituting the value of "y", we get
So, the numbers are

The element on the position (1,1) in the product matrix FC is a scalar product of the first row in F and the first column in C.
Therefore the element in the position (1,1) in FC will be a scalar product of (-2,0) and (12,1):
The only matrix that has a value of -24 in the position (1,1) is matrix B.
Therefore, the answer is matrix B.
