We first sort the items into fixed assets, current assets, current liabilities and trading figures.

(a) Fixed assets

Fixed assets are long-lasting assets used in running the business. Here they are Premises, Machinery and Plant.

Premises \(20{,}000\) + Machinery \(20{,}000\) + Plant \(30{,}000\)

\[\text{Fixed assets} = 20{,}000 + 20{,}000 + 30{,}000 = \text{N}70{,}000\]

(b) Working capital

Working capital = Current assets - Current liabilities.

Current assets = Cash \(20{,}000\) + Debtors \(30{,}000\) + Stock \(50{,}000 = 100{,}000\).

Current liabilities = Creditors \(= 20{,}000\).

\[\text{Working capital} = 100{,}000 - 20{,}000 = \text{N}80{,}000\]

(c) Gross profit

Gross profit = Sales - Cost of goods sold.

\[\text{Gross profit} = 200{,}000 - 100{,}000 = \text{N}100{,}000\]

(d) Net profit

Net profit = Gross profit - Expenses. The only expense given is Rent \(= 10{,}000\).

\[\text{Net profit} = 100{,}000 - 10{,}000 = \text{N}90{,}000\]

Summary: Fixed assets = N70,000; Working capital = N80,000; Gross profit = N100,000; Net profit = N90,000.
