To Find:

• Matrix representing summarized sales of the year 2019
• Matrix representing summarized sales of the year 2020
• Matrix representing sales in all years

Step-by-step explanation:

• Matrix representing summarized sales of the year 2019

                               

     Option (B)  $\left[\begin{array}{ccc}120&50&10\\100&30&5\\90&40&2\end{array}\right]$

• Matrix representing summarized sales of the year 2020

         

     Option(A)  $\left[\begin{array}{ccc}300&150&20\\200&50&6\\100&60&5\end{array}\right]$

• Matrix representing sales in all years

• Adding both the sales,
• $\left[\begin{array}{ccc}120&50&10\\100&30&5\\90&40&2\end{array}\right] + \left[\begin{array}{ccc}300&150&20\\200&50&6\\100&60&5\end{array}\right] = \left[\begin{array}{ccc}420&200&30\\300&80&11\\190&100&7\end{array}\right]$

     Option(C)$\left[\begin{array}{ccc}420&200&30\\300&80&11\\190&100&7\end{array}\right]$
