## 51. One disadvantage of using North-West Corner rule to find initial solution to the transportation problem is that.

## 52. The solution to a transportation problem with ‘m’ rows (supplies) & ‘n’ columns (destination) is feasible if number of positive allocations are.

## 53. If an opportunity cost value is used for an unused cell to test optimality, it should be.

## 54. During an iteration while moving from one solution to the next, degeneracy may occur when.

## 55. The large negative opportunity cost value in an unused cell in a transportation table is chosen to improve the current solution because.
