Given matrix A contains the costs per contact in paisa for different types of contacting the public.

Matrix B contains the number of contacts of each type made in two cities X and Y.

mount spent in City X = 990000 paisa = Rs 9900

Amount spent in City Y = 2120000 paisa = Rs 21200

Total amount spent = Rs (9900 + 21200) = Rs 31110
