| B. | prevent solution from becoming degenerate |
| C. | ensure that total cost does not exceed a limit |
| D. | none of the above |
| Answer» A. satisfy rim conditions | |
| 12. |
The occurrence of degeneracy while solving a transportation problem means that |
| A. | total supply equals total demand |
| B. | the solution so obtained is not feasible |
| C. | the few allocations become negative |
| D. | none of the above |
| Answer» B. the solution so obtained is not feasible | |
| 13. |

| D. | none of the above |
| Answer» B. positive with at least one equal to zero | |
| 14. |
One disadvantage of using North-West Corner rule to find initial solution to the transportation problem is that |
| A. | it is complicated to use |
| B. | it does not take into account cost of transportation |
| C. | it leads to a degenerate initial solution |
| D. | all of the above |
| Answer» B. it does not take into account cost of transportation | |
| 15. |

| B. | m*n |
| C. | m+n-1 |
| D. | m+n+1 |
| Answer» C. m+n-1 | |
| 16. |
If an opportunity cost value is used for an unused cell to test optimality, it should be |
| A. | equal to zero |
| B. | most negative number |
| C. | most positive number |
| D. | any value |
| Answer» B. most negative number | |
| 17. |
