| Opening stock (1 Jan 2018) | 20,000 | |
| Add: Purchases | 150,000 | |
| Add: Carriage inwards | 4,000 | |

(a) Cost of goods sold
= Opening stock + Purchases + Carriage inwards - Closing stock
= 20,000 + 150,000 + 4,000 - 35,000 = N139,000
(b) Gross profit
= Sales - Cost of goods sold = 230,000 - 139,000 = N91,000
(c) Net profit
In the Profit and Loss Account the gross profit is brought down, other income (rent received) is added and the running expense (salaries) is deducted:
= Gross profit + Rent received - Salaries
= 91,000 + 80,000 - 29,000 = N142,000
(d) Percentage of gross profit (on sales)
\[ \frac{\text{Gross profit}}{\text{Sales}} \times 100 = \frac{91,000}{230,000} \times 100 = 39.57\% \]
