\begin{align*} Sales &&& $500,000 \ \text{Less: Cost of Goods Sold} \ \text{Opening Stock} & $25,000 \ Add: Purchases & $325,000 \ \text{Add: Carriage Inwards} & $1,800 \ Goods Available for Sale & $351,800 \ \text{Less: Closing Stock} & ($35,000) \ Cost of Goods Sold &&& ($316,800) \ \text{Gross Profit} &&& $183,200 \ \ Add: Other Income \ Discounts received & $1,825 \ \text{Total Income} &&& $185,025 \ \ Less: Operating Expenses \ Salaries & wages & $96,000 \ \text{Telephone & postage} & $9,250 \ Electricity & $10,000 \ \text{Service & maintenance} & $21,000 \ Motor vehicle running expenses & $18,000 \ \text{Interest on Mortgage loan} & $9,375 \ Bad debts & $3,600 \ \text{Discounts allowed} & $2,500 \ Total Operating Expenses &&& ($169,725) \ \textbf{Net Profit} &&& \boxed{\mathbf{$15,300}} \end{align*}

\begin{align*} Assets \ Non-current Assets \ Business premises & $244,000 \ \text{Motor vehicle} & $175,000 \ Furniture & equipment & $50,000 \ \text{Total Non-current Assets} && $469,000 \ \ Current Assets \ Debtors & $115,000 \ \text{Closing Stock} & $35,000 \ Total Current Assets && $150,000 \ \textbf{Total Assets} &&& \mathbf{$619,000} \ \ Equity and Liabilities \ Equity \ Capital (Opening) & $400,000 \ \text{Add: Net Profit} & $15,300 \ Less: Drawings & ($20,000) \ \text{Closing Capital} && $395,300 \ \ Non-current Liabilities \ Mortgage loans && $125,000 \ \ \textbf{Current Liabilities} \ \text{Creditors} && $94,000 \ Total Equity and Liabilities &&& $614,300 \end{align*}
Note: The Statement of Financial Position does not balance. Total Assets ($619,000) do not equal Total Equity and Liabilities ($614,300). This is due to the original trial balance being unbalanced by $10,300 (Credit side higher than Debit side). The difference in the Statement of Financial Position is$4,700 ($619,000 -$614,300). This indicates an additional error in the trial balance or an unrecorded item.
