Neco 2025 Data Processing Question 26

The following sales data are recorded in a spreadsheet:\n\nProduct A: unit price \(\text{₦}1200\), cost per unit \(\text{₦}700\); quantities Jan 140, Feb 160, Mar 130.\nProduct B: unit price \(\text{₦}950\), cost per unit \(\text{₦}600\); quantities Jan 200, Feb 180, Mar 210.\nProduct C: unit price \(\text{₦}1500\), cost per unit \(\text{₦}1000\); quantities Jan 90, Feb 110, Mar 95.\nProduct D: unit price \(\text{₦}800\), cost per unit \(\text{₦}500\); quantities Jan 250, Feb 240, Mar 260.\n\nA discount rule in the spreadsheet is: if the quantity sold for a product in a month exceeds \(150\) units, the unit price for that month is reduced by \(10\%\) before calculating revenue.\n\nUsing this rule, calculate the total profit for product \(B\) over the three months. (Profit = total revenue - total cost.)
