(a) Cost of goods sold
= Opening stock + Purchases - Closing stock
= 3,000 + 7,000 - 2,000 = N8,000
(b) Net profit percentage
Gross profit = Sales - Cost of goods sold = 12,000 - 8,000 = N4,000
Total expenses = Wages + Transport + Electricity = 500 + 400 + 300 = N1,200
Net profit = Gross profit - Expenses = 4,000 - 1,200 = N2,800
\[ \text{Net profit \%} = \frac{\text{Net profit}}{\text{Sales}} \times 100 = \frac{2,800}{12,000} \times 100 = 23.33\% \]
(c) Rate of turnover
Average stock = (Opening stock + Closing stock) / 2 = (3,000 + 2,000) / 2 = N2,500
\[ \text{Rate of turnover} = \frac{\text{Cost of goods sold}}{\text{Average stock}} = \frac{8,000}{2,500} = 3.2 \text{ times} \]
