4. a) A marketing manager have five salesmen and five sales districts. Considering the
capabilities of the salesmen and the nature of districts, the marketing manager
estimates that sales per month (in hundred rupees) for each salesman in each district
would be as follows:
Districts
A B C D E
1 32 38 40 28 40
2 40 24 28 21 36
Salesman 3 41 27 33 30 37
4 22 38 41 36 36
5 29 33 40 35 39
Find the assignment of salesmen to districts that will result in maximum sales.
