How this paper was built
This is a TutorZone original mock paper: the questions follow the 2027 framework’s structure (Paper 1 at 25% in 1 hour, Section A 17% and Section B 8%) and the answers are our own, not HKEAA past papers or marking references.
HKEAA publishes no fixed question count, so this paper sets its own: 15 MC items and 3 short questions. Every numeric answer was recomputed programmatically.
Pacing
| Section | Marks | Suggested time | What to do first |
|---|---|---|---|
| Section A (multiple-choice) | 17% | about 30 min | Know the accounting equation and ratios; calculation marks are non-negotiable |
| Section B (three short questions) | 8% | about 25-30 min | Both sides of every entry; show the working |
| Paper 2 (Elective Part, separate paper) | 75% | not covered here | This paper covers Paper 1 only |
How should the 60 minutes be split?

Section B: short questions (3 questions, 20 marks)
Aim for 25-30 minutes. Write both sides of every entry and show your working.
Question 1 (6 marks)
On 31 December a firm’s cash book shows $12 400 and the bank statement shows $13 800. Unpresented cheques are $2 000; a note collected by the bank of $600 is not yet in the cash book; bank charges of $200 are not yet in the cash book. (a) Find the adjusted bank balance; (b) show how the bank charges are recorded.
Question 2 (7 marks)
A machine costs $150 000 with an estimated residual value of $15 000 and a 5-year life, depreciated on the straight-line method. (a) Find the annual depreciation; (b) write the first year’s depreciation entry; (c) find the net book value at the end of year 3.
Question 3 (7 marks)
A product sells at $20 with a unit variable cost of $8 and fixed costs of $60 000 per month. (a) Find the unit contribution; (b) find the break-even quantity and sales revenue; (c) how many units are needed to earn $24 000?
Where are the answers, and do they show the steps?
Direct answer: each question is followed by an answer-and-marks block with the entries (debit and credit), the calculation steps and the marks each earns (depreciation: 2 marks for the annual charge, 3 for the entry, 2 for the net book value), plus the usual losses.
Section A answers and explanations
Question 1
Answer: A ($320 000) Accounting equation: capital = assets − liabilities = 500 000 − 180 000.
Question 2
Answer: B ($18 000) Depreciation = (cost − residual) ÷ life = 90 000 ÷ 5.
Question 3
Answer: C (Accrued expenses (liabilities)) An accrued expense is a service used but unpaid: it belongs in this year’s profit and loss and as a current liability.
Question 4
Answer: B (Debit bad debts, credit accounts receivable) Bad debt is an expense, so debit bad debts and credit accounts receivable.
Question 5
Answer: A ($8) Variable cost is 40% of the price: 20 × 0.4 = 8, leaving a contribution of 12.
Question 6
Answer: B (5 000 units) Unit contribution = 20 − 8 = 12, so break-even = 60 000 ÷ 12.
Question 7
Answer: B (7 000 units) (fixed costs + target profit) ÷ unit contribution = 84 000 ÷ 12.
Question 8
Answer: A (40%) Gross profit margin = gross profit ÷ sales = 50 000 ÷ 125 000.
Question 9
Answer: A (Inventory) Inventory is expected to convert to cash within one operating cycle, so it is current.
Question 10
Answer: C (Check whether the totals of debits and credits are equal) It checks that debits equal credits, though it cannot reveal omissions, double entries or compensating errors.
Question 11
Answer: B (The owner has unlimited liability for debts) The owner has unlimited liability, so personal assets may be used to settle business debts.
Question 12
Answer: D (Deduct from the bank balance to arrive at the adjusted bank balance) They are issued but not yet paid by the bank, so the bank statement balance is still too high and they are deducted.
Question 13
Answer: B (Direct materials, direct labour and direct expenses) Prime cost is direct materials plus direct labour plus direct expenses; overheads are indirect.
Question 14
Answer: D ($4 000) Gross profit = sales − cost of goods sold = 12 000 − 8 000.
Question 15
Answer: A ($2 000) 40 000 × 5% = 2 000 (a deduction from receivables).
Section B answers and mark allocation
Question 1
(a) $13 800 − $2 000 unpresented = $11 800 (3 marks). (b) debit bank charges (an expense) and credit bank $200 (2 marks); the note collected is debit bank, credit notes receivable $600 (1 mark). The corrected cash book balance is 12 400 − 200 + 600 = $12 800.
Question 2
(a) (150 000 − 15 000) ÷ 5 = $27 000 (2 marks); (b) Dr depreciation expense $27 000, Cr accumulated depreciation – machinery $27 000 (3 marks); (c) 150 000 − 27 000 × 3 = $69 000 (2 marks).
Question 3
(a) 20 − 8 = $12 (2 marks); (b) 60 000 ÷ 12 = 5 000 units and revenue 5 000 × 20 = $100 000 (3 marks); (c) (60 000 + 24 000) ÷ 12 = 7 000 units (2 marks).
Where are Paper 1 marks most easily lost?
Direct answer: one-sided entries; depreciation without deducting the residual value; break-even calculated from the price instead of the contribution; and unpresented cheques added in the wrong direction on a bank reconciliation (they make the bank balance too high, so they are deducted).
Where these marks are usually lost
| Mistake | What it looks like | What it costs | Instead |
|---|---|---|---|
| One-sided entries | Debit only, or an amount with no double entry | Double entry must balance; a single side earns nothing | Write the debit, then the credit, then check they match |
| Forgetting residual value | Cost ÷ life | Residual value must come out first | Depreciation = (cost − residual) ÷ life |
| Wrong base for break-even | Using the price instead of the contribution | Break-even = fixed costs ÷ unit contribution | Work out the contribution first |
| Reconciliation direction | Adding unpresented cheques to the bank balance | They make the bank balance too high, so they are deducted | Decide which book has not yet recorded the item |
How to use this paper
First sit: no references, the full 60 minutes, a calculator only.
Mark it: check both sides of every entry and rewrite the steps of each calculation.
Second sit: finish inside 45 minutes with every entry balanced.
What should I do after this paper?
Direct answer: put the key formulas on one page (depreciation, contribution, break-even, gross margin); rewrite every wrong entry with both sides; drill past-paper questions by topic; and redo this paper three to seven days later.
