A company has 3 plants A, B, C and 3 warehouses X, Y, Z. Number of units available at plants is 60, 70 and 80 respectively and demands at warehouses are 50, 80 and 80 respectively. Unit costs of transportation are as follows :
| Plant | X | Y | Z |
|---|---|---|---|
| A | 8 | 7 | 3 |
| B | 3 | 8 | 9 |
| C | 11 | 13 | 5 |
Answer and explanation
Correct answer D
The allocation satisfies every supply and demand, and its four positive cells contain no transportation loop, so it is a basic feasible solution. It is degenerate because there are only four positive allocations, fewer than . Moving 20 units from BZ and CY to BY and CZ preserves feasibility and changes cost by , proving that the allocation is not optimal.
