The northwest-corner rule starts with the cell in the top-left corner of the table and allocates as much as possible to that cell until either the supply or demand for that cell is exhausted. In this case, starting at Source 1 - Destination 1, we can allocate 10. Then we move to the next cell to the right (Source 1 - Destination 2) and allocate the remaining supply there, which is 20 - 10 = 10. Finally, we move down to Source 3 - Destination 2 and allocate 15 there. At this point, we have exhausted all of the supply from Source 3 and can allocate no more to any destination from that source. Therefore, the northwest-corner allocation for Source 3 - Destination 3 is 0.
