Gce Model Questions Vol1 2021 Commerce Question 13

A wholesaler purchases a batch of \(500\) units from a manufacturer whose list price is \(\text{₦}1{,}200{,}000\). The wholesaler receives a trade discount of \(12\%\) on the list price and, if payment is made within \(10\) days, an additional cash discount of \(3\%\) on the discounted price. The wholesaler then applies a markup of \(25\%\) on his cost price and offers retailers a bulk‑purchase discount of \(5\%\) on the marked‑up price when they buy at least \(300\) units. Calculate the selling price per unit for a retailer buying \(350\) units, and compute the wholesaler's profit margin (percentage profit on cost) for that transaction. Give the selling price to two decimal places and the profit margin as a percentage to two decimal places.
