Incomplete records: practice questions

How to approach these questions

Incomplete records questions ask you to rebuild a full set of figures from the fragments a small trader keeps. These might be a few bank statements, a list of assets and liabilities, and notes about cash taken or paid. Read the requirement to see exactly what is asked.

Sometimes you need a single number, such as profit for the year or purchases. Sometimes you need a complete income statement. Underline the target figure, so you do not produce a full set of accounts when one calculation earns the marks.

Then scan the data twice: once for the opening and closing positions, and once for the movements in between. The whole topic rests on one idea: closing capital equals opening capital plus profit plus any capital introduced, minus drawings.

Establish opening capital first. Build a quick statement of affairs at the start of the year: list the assets and subtract the liabilities. The difference is opening capital.

Repeat for the year end to get closing capital. Show both statements clearly, because the layout itself carries method marks. Then rearrange the capital equation to find whatever is missing.

For example, closing capital is RM48,000, opening capital is RM30,000, and drawings were RM12,000, with no capital introduced. Profit is 48,000 − 30,000 + 12,000 = RM30,000.

Write the rearrangement out line by line. It protects you if one input is wrong.

Many questions ask for a figure found through a control account or a cash summary. To find credit sales, open a total trade receivables account. Put the opening balance and credit sales on one side.

Put receipts, discounts allowed and bad debts on the other. The closing balance completes it. Credit purchases come from the matching total trade payables account.

Cash drawings or missing takings come from a cash and bank summary. Enter every known receipt and payment and let the balancing figure reveal the unknown.

Draw proper T-accounts with a clearly labelled balancing figure. That earns marks even if a later arithmetic slip costs you the final answer.

Mark-up and margin often help you find the missing figures. A mark-up makes gross profit a percentage of cost of sales. A margin makes it a percentage of sales.

Confusing them reverses your calculation. Suppose sales are RM60,000 and the mark-up is 25% on cost. Cost of sales is 60,000 ÷ 1.25 = RM48,000, and gross profit is RM12,000.

Write down which base you are using before you divide. To find closing inventory or a figure lost in a fire, use the trading account in reverse. Work from sales and the profit percentage back to cost of sales, then to purchases or the missing inventory.

Test your answer. Recompute closing capital from your derived profit and check it equals the closing statement of affairs. Ask whether drawings look reasonable compared with profit.

Ask whether purchases sit sensibly above cost of sales, given the inventory movement. A figure entered on the wrong side of a control account is the most common slip, and a quick reasonableness check often catches it.

Avoid this trap: drawings are not an expense in the income statement. They belong only in the capital section.

Goods taken by the owner reduce purchases and increase drawings. Charge depreciation even when records are thin, and adjust the expenses you enter for accruals and prepayments.

Never confuse cash received with sales, or cash paid with purchases, when the business trades on credit. Show every control account and every rearranged equation in full, because in this topic the method earns most of the marks.
