Question 1 Report

A market stallholder buys 40 kg of apples at £1.20 per kg, shown in the table.

Bought40 kg at £1.20/kg
Sold at marked price32 kg
Sold at a discount8 kg, 25% off
  1. Work out the total cost of the apples. (1)
  2. The stallholder marks up the cost price by 60% to set the price per kg. Work out this marked price. (2)
  3. Using the table, work out the total revenue for the day. (3)
  4. Work out the profit as a percentage of the cost price. (1)
  5. The target was a profit margin of at least 50%. State, with a reason, whether this was met. (1)

Answer Details

This question works through a full profit calculation for a market trader: total cost, a percentage mark-up, mixed full-price and discounted revenue, and a final profit-margin check against a target.

  1. \[40 \times £1.20 = £48\]

    The total cost is \(£48\) [1 mark].

  2. Marking up the cost price by \(60\%\):

    \[£1.20 \times 1.60 = £1.92 \text{ per kg}\]

    [2 marks]

  3. The discounted price is \(£1.92 \times 0.75 = £1.44\) per kg. Total revenue combines both parts of the sale:

    \[32 \times £1.92 + 8 \times £1.44 = £61.44 + £11.52 = £72.96\]

    [3 marks]

  4. Profit is \(£72.96 - £48 = £24.96\). As a percentage of the cost price:

    \[\dfrac{24.96}{48} \times 100 = 52\%\]

    [1 mark]

  5. Since \(52\% \gt 50\%\), the target profit margin of at least \(50\%\) was met [1 mark].

Profit margin here is calculated on the cost price throughout (\(£48\)), not on the revenue, which is why part (d) divides by \(48\) rather than by \(72.96\).
