Suppose we have to allocate 4 tasks (1, 2, 3, and 4) between four people. The costs are set out in the following table:

	Task
Person	1	2	3	4
Fatima	5	23	14	8
Mohamed	10	25	1	23
Ali	35	16	15	12
Maryam	16	23	21	7

The entries in the table denote the costs of assigning a task to a particular person. The plant supervisor would like to assign tasks so that total time is minimized. What is the minimum cost assignment of Ali to tasks?
