Answer :
The profit computation for IPD is the selling price (N16) minus variable cost (N4), which equals N12. The profit computation for EMD is transfer price (N16) minus total cost (N12), which equals N4.
The company's overall profit is sum of IPD's and EMD's profits, which is N16. IPD would select a selling price of N16, as this is the transfer price offered by EMD. The quantity would depend on the demand from external customers. The selling price in the overall company interest would be N16, as it maximizes the company's profit. The managers of IPD and EMD may have different reactions.
IPD's manager would prefer a higher selling price to increase IPD's profit, while EMD's manager may prefer a lower selling price to increase the internal sales volume. A resolution could involve negotiating a transfer price that benefits both divisions while maximizing the company's profit.
