Here Total Demand = 260 is less than Total Supply = 300. So We add a dummy demand constraint with 0 unit cost and with allocation 40. Now, The modified table is D 1 D 2 D 3 D 4 D dummy

In 1 st row, The smallest transportation cost is 1 in cell S 1D 1. The allocation to this cell is min(60,70) = 60. This exhausts the capacity of S 1 and leaves 70 - 60=10 units with D 1 Table-1 D1

The maximum profit = 3 × 60 + 4 × 50 + 2 × 20 + 4 × 10 + 3 × 30 + 4 × 40 + 2 × 50 + 0 × 40 = 810 Here, the number of allocated cells = 8 is equal to m + n - 1 = 4 + 5 - 1 = 8 ∴ This solution is non-degenerate
