The northwest corner rule allocates supply to demand starting from the top-left corner (northwest) of the table and moving towards the bottom-right (southeast), filling as much demand as possible from each source before moving to the next. Following this rule:- Source 1 (30 units) fully satisfies Dest. 1 (15 units) and partially satisfies Dest. 2 (15 of 50 units), exhausting its supply.- Source 2 (40 units) then continues to satisfy Dest. 2 (35 of the remaining 35 units) and partially satisfies Dest. 3 (5 of 25 units), exhausting its supply.- Source 3 (20 units) is left to satisfy the remaining demand of Dest. 3 (20 of the remaining 20 units).Therefore, the allocation to the cell Source 3-Destination 3 is 20 units.
