) Consider the following transp. problem, where the unit transportation costs ($/unit) are as follows from source i to destination j; Cij ; 9, 6,5,8. Where i = 1, j = 1,2,3,4. respectively Cij ; 10,5,7,3. Where i= 2, j = 1,2,3,4. respectively Cij ; 4,7,8,10. Where i= 3, j = 1,2,3,4. respectively Cij ; 6, 8,4,9. Where i = 4, j = 1,2,3,4. respectively

Also,source and destination constraints (Units) are given as follows:

Source constraints are : 90,50,70 and 60; for sources 1,2,3 and 4 respectively.

Destination constraints : 60,40,80 and 90, for destinations 1,2,3 and 4 respectively
