In a parliament election, a political party hired a public relations firm to promote its candidates in three ways – telephone, house calls and letters. The cost per contact (in paisa) is given in matrix A as


The number of contacts of each type made in two cities X and Y is given in matrix B as



Find the total amount spent by the party in the two cities.


What should one consider before casting his/her vote – party’s promotional activity or their social activities?

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.



Now, the total amount spent by the political party in the two cities for contacting the public can be obtained by taking the product of the matrices B and A.






Amount 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


Thus, the total amount spent by the party in both the cities is Rs 31110 with Rs 9990 spent in city X and Rs 21200 spent in city Y.


One must surely consider the party’s social activities instead of their promotional activities before casting his/her vote.
