This mirrors the CCEA A2 Unit 1 exam format, so time management is critical. Allocate roughly 30 minutes to Section A, 45 minutes to Section B, and 45 minutes to Section C. Practising under timed conditions helps you calibrate your pace.
这套模拟卷仿照 CCEA A2 第一单元的真实考试结构，因此时间管理至关重要。大约分配 30 分钟给 A 部分、45 分钟给 B 部分、45 分钟给 C 部分。在限时条件下练习有助于你校准答题节奏。
2. Question 1: Average Rate of Return (ARR) | 第 1 题：平均收益率
The question states: “Daybreak Ltd is considering purchasing new machinery costing £120 000. The machine will generate net cash flows of £40 000 per year for 4 years, after which it will have zero scrap value. Calculate the ARR and comment on the result.”
题目如下：“Daybreak 公司考虑购买新机器，成本为 120 000 英镑。该机器将在 4 年内每年产生 40 000 英镑的净现金流，期满后无残值。计算平均收益率并评价结果。”
ARR is calculated as (average annual profit / initial investment) × 100%. Since there is no scrap value and no information about depreciation method, total profit = total net cash flows – initial cost = (4 × £40 000) – £120 000 = £160 000 – £120 000 = £40 000. Average annual profit = £40 000 / 4 = £10 000. ARR = (£10 000 / £120 000) × 100% = 8.33%.
ARR 计算为（平均年利润 / 初始投资额）× 100%。由于无残值且未提供折旧方法，总利润 = 总净现金流 – 初始成本 = (4 × £40 000) – £120 000 = £160 000 – £120 000 = £40 000。平均年利润 = £40 000 / 4 = £10 000。ARR = (£10 000 / £120 000) × 100% = 8.33%。
Evaluation: An ARR of 8.33% should be compared to the company’s target rate or the return on alternative investments. The method is simple and uses familiar profit figures, but it ignores the time value of money and cash flows after the project’s lifetime. Students often forget to deduct the initial cost when calculating total profit; others misplace the numerator by using average investment, which is not required here unless specified.
评价：8.33% 的 ARR 应与公司的目标收益率或其他投资的回报进行比较。该方法简单易用且基于熟悉的利润数字，但忽略了货币的时间价值和项目结束后的现金流。学生在计算总利润时经常忘记扣除初始成本；还有人误用平均投资额作为分母，除非题目明确要求，否则此处不需要。
3. Question 2: Payback Period and Limitations | 第 2 题：投资回收期及其局限性
The scenario provides two projects, X and Y, with uneven cash flows. Project X: initial cost £80 000, inflows Year 1 £30 000, Year 2 £35 000, Year 3 £20 000, Year 4 £5 000. Project Y: initial cost £80 000, inflows Year 1 £15 000, Year 2 £25 000, Year 3 £40 000, Year 4 £25 000. You are asked to calculate the payback period for each and advise which is preferable.
题目给出了两个项目的非均匀现金流。项目 X：初始成本 80 000 英镑，第 1 年流入 30 000，第 2 年 35 000，第 3 年 20 000，第 4 年 5 000。项目 Y：初始成本 80 000 英镑，第 1 年流入 15 000，第 2 年 25 000，第 3 年 40 000，第 4 年 25 000。要求计算各自的回收期，并建议哪个更可取。
For Project X, cumulative inflows reach £65 000 by end of Year 2, leaving £15 000 to recover. During Year 3 £20 000 is received, so payback = 2 + (15 000 / 20 000) = 2.75 years. For Project Y, cumulative after Year 2 is £40 000, after Year 3 is £80 000, so payback = exactly 3 years. Based solely on payback, Project X is preferable because it recovers the investment faster.
项目 X 累计流入第 2 年末达 65 000 英镑，还需回收 15 000 英镑。第 3 年收到 20 000 英镑，因此回收期 = 2 + (15 000 / 20 000) = 2.75 年。项目 Y 第 2 年末累计 40 000 英镑，第 3 年末正好 80 000 英镑，回收期为 3 年整。仅按回收期看，项目 X 更优，因为它更快收回投资。
However, payback ignores the total return beyond the cutoff and the time value of money. Project Y generates £105 000 in total versus £90 000 for X, so it may be more profitable overall. Mention this in evaluation to show balanced judgement.
然而，回收期忽略了截止点之后的总回报以及货币的时间价值。项目 Y 共产生 105 000 英镑，而 X 总计 90 000 英镑，因此 Y 整体可能利润更高。在评价中提及这一点，以展现均衡的判断。
4. Question 3: Net Present Value (NPV) | 第 3 题：净现值
The question gives discount factors: Year 1: 0.909, Year 2: 0.826, Year 3: 0.751, Year 4: 0.683. Using the same Project X and Y data, students must calculate NPV at a 10% discount rate and explain why NPV is more robust than ARR and payback.
题目给出了折现因子：第 1 年 0.909，第 2 年 0.826，第 3 年 0.751，第 4 年 0.683。要求学生使用相同的项目 X 和 Y 数据，按 10% 折现率计算净现值，并解释为何 NPV 比 ARR 和回收期更稳健。
Project X NPV: (30 000 × 0.909) + (35 000 × 0.826) + (20 000 × 0.751) + (5 000 × 0.683) – 80 000. Calculated: 27 270 + 28 910 + 15 020 + 3 415 = £74 615. NPV = £74 615 – £80 000 = -£5 385. Project Y NPV: (15 000 × 0.909) + (25 000 × 0.826) + (40 000 × 0.751) + (25 000 × 0.683) – 80 000 = 13 635 + 20 650 + 30 040 + 17 075 = £81 400; NPV = £81 400 – £80 000 = £1 400.
项目 X 净现值：(30 000 × 0.909) + (35 000 × 0.826) + (20 000 × 0.751) + (5 000 × 0.683) – 80 000。计算结果：27 270 + 28 910 + 15 020 + 3 415 = 74 615 英镑。NPV = 74 615 – 80 000 = -5 385 英镑。项目 Y NPV：(15 000 × 0.909) + (25 000 × 0.826) + (40 000 × 0.751) + (25 000 × 0.683) – 80 000 = 13 635 + 20 650 + 30 040 + 17 075 = 81 400 英镑；NPV = 81 400 – 80 000 = 1 400 英镑。
A negative NPV signals a loss in real terms, so Project X should be rejected. Project Y has a positive NPV, indicating it adds value. NPV accounts for the time value of money and all project cash flows. It is preferred in theory, but students must note that NPV depends on accurate discount rate estimation.
负值 NPV 表明实际亏损，因此项目 X 应被拒绝。项目 Y 的 NPV 为正，说明其能创造价值。NPV 考虑了货币的时间价值和项目所有现金流。理论上 NPV 更优，但学生必须指出 NPV 依赖于对折现率的准确预估。
5. Question 4: Decision Tree Analysis | 第 4 题：决策树分析
A firm must decide whether to launch a new product nationally or regionally first. National launch costs £80 000 and has a 60% chance of high demand generating £200 000 profit, and a 40% chance of low demand giving a loss of £50 000. Regional launch costs £30 000, with a 70% chance of high demand returning £100 000 and a 30% chance of low demand yielding £10 000. Recommend the best option using expected monetary value.
一家公司须决定是面向全国发布新产品还是先区域发布。全国发布成本 80 000 英镑，有 60% 概率高需求带来 200 000 英镑利润，40% 概率低需求导致 50 000 英镑亏损。区域发布成本 30 000 英镑，有 70% 概率高需求收益 100 000 英镑，30% 概率低需求收益 10 000 英镑。使用期望货币值给出建议。
EMV (National) = (0.6 × £200 000) + (0.4 × -£50 000) – £80 000 = £120 000 – £20 000 – £80 000 = £20 000. EMV (Regional) = (0.7 × £100 000) + (0.3 × £10 000) – £30 000 = £70 000 + £3 000 – £30 000 = £43 000. Regional launch yields higher EMV (£43k > £20k), so it is recommended.
全国发布的期望货币值 = (0.6 × £200 000) + (0.4 × -£50 000) – £80 000 = £120 000 – £20 000 – £80 000 = £20 000。区域发布的 EMV = (0.7 × £100 000) + (0.3 × £10 000) – £30 000 = £70 000 + £3 000 – £30 000 = £43 000。区域发布产生更高的 EMV (43k > 20k)，故推荐该方案。
While EMV provides a clear numerical basis, it relies on estimated probabilities. If the firm is risk-averse, it may still prefer the regional option because the worst-case scenario for regional is a £10 000 profit (minus cost) whereas national could lose £130 000 overall. Include this argument for a higher-level evaluation.
尽管 EMV 提供了清晰的数值依据，但它依赖于估计的概率。如果企业属于风险规避型，它仍可能偏好区域方案，因为区域最差情况是 10 000 英镑利润（减去成本后有净利），而全国可能总体损失 130 000 英镑。在高层级评价中应包含这一论点。
6. Question 5: Critical Path Analysis and Float | 第 5 题：关键路径分析与时差计算
Given a network diagram with activities A–F, duration in days: A(3), B(4), C(2), D(5), E(3), F(2). A and B start at node 1. A precedes C; B precedes D and E; C and D precede F. Students must calculate EST, LFT and float for each activity, identify the critical path, and explain the implication of float for management.
给出网络图，包含活动 A–F，持续时间（天）：A(3), B(4), C(2), D(5), E(3), F(2)。A 和 B 始于节点 1。A 后接 C；B 后接 D 和 E；C 和 D 后接 F。学生需计算每个活动的 EST、LFT 与时差，找出关键路径，并解释时差对管理的意义。
Forward pass: EST A = 0, EFT = 3; EST B = 0, EFT B = 4. EST C = 3, EFT C = 5. EST D = 4, EFT D = 9; EST E = 4, EFT E = 7. Activity F depends on C (EFT 5) and D (EFT 9), so EST F = 9, EFT F = 11. Project duration = 11 days. Backward pass: LFT F = 11, LST F = 9. LFT D = 9, LST D = 4. LFT C = 9, LST C = 7 (must not delay F beyond 9). LFT E = 11, LST E = 8. LFT B = min(LST D, LST E) = min(4, 8) = 4, LST B = 0. LFT A = LST C = 7, LST A = 4.
前推法：EST A=0, EFT=3；EST B=0, EFT B=4。EST C=3, EFT C=5。EST D=4, EFT D=9；EST E=4, EFT E=7。活动 F 依赖 C (EFT 5) 和 D (EFT 9)，因此 EST F=9, EFT F=11。项目总工期为 11 天。后推法：LFT F=11, LST F=9。LFT D=9, LST D=4。LFT C=9, LST C=7。LFT E=11, LST E=8。LFT B=min(LST D, LST E)=min(4,8)=4, LST B=0。LFT A=LST C=7, LST A=4。
Float = LST – EST or LFT – EFT. Float A = 4 – 0 = 4 days; Float B = 0; Float C = 7 – 3 = 4 days; Float D = 4 – 4 = 0; Float E = 8 – 4 = 4 days; Float F = 9 – 9 = 0. Critical path is B → D → F, length 4+5+2=11. Activities with zero float are critical; delay here delays the whole project. Float on A, C and E allows managers to shift resources elsewhere.
时差 = LST – EST 或 LFT – EFT。A 时差 = 4-0=4 天；B 时差=0；C 时差=7-3=4 天；D 时差=0；E 时差=8-4=4 天；F 时差=0。关键路径为 B → D → F，长度 4+5+2=11。时差为零的活动是关键活动，此处延误将使整个项目延期。A、C 和 E 的时差让管理者可将资源调配到其他活动中。
7. Question 6: Stakeholder Mapping and Conflict | 第 6 题：利益相关者映射与冲突
Using Mendelow’s matrix, students must map four stakeholders of a supermarket planning a large out-of-town store: local residents (high interest, low power), a major investor (high power, high interest), small shopkeepers (high interest, low power), and the local council (high power, high interest). The task is to recommend strategies for each group.
学生需运用门德洛矩阵，将一家拟建大型城外门店的超市的四方利益相关者进行映射：当地居民（高兴趣、低权力）、大投资者（高权力、高兴趣）、小店主（高兴趣、低权力）和地方议会（高权力、高兴趣）。要求为每个群体推荐策略。
Local residents and small shopkeepers fall into the ‘keep informed’ quadrant because they lack power but care deeply. The supermarket should maintain transparent communication to minimise opposition. The investor and the council are ‘key players’: they require close management, active participation and regular dialogue. Confusing the categories is a common mistake – students often treat local councils as low-power groups because they misunderstand planning authority.
当地居民和小店主属于“保持沟通”象限，因为他们缺乏权力但高度关注。超市应保持透明沟通，减少反对意见。投资者和议会是“关键参与者”，需要紧密管理、积极参与和定期对话。混淆分类是常见错误——学生常误以为地方议会权力低，因为他们误解了规划审批的权限。
A well-structured answer will also note potential conflicts: residents may oppose while the council backs the project for economic gains. The business must balance these stakeholder interests to avoid reputational damage.
结构良好的答案还会指出潜在的冲突：居民可能反对，而议会为经济利益支持项目。企业必须平衡这些利益相关者的利益，以免声誉受损。
8. Section B: Break-even and Contribution Analysis | B 部分：盈亏平衡与贡献分析
The case study describes a manufacturer of smart thermostats. Selling price £120, variable cost £70 per unit, fixed costs £300 000 per year. Question (a): Calculate break-even output and margin of safety if expected sales are 8 000 units. (b): Discuss the impact of a 10% price reduction on break-even and profit, assuming sales volume rises to 9 500 units.
案例描述一家智能温控器制造商。售价 120 英镑，单位变动成本 70 英镑，年固定成本 300 000 英镑。问题 (a)：计算盈亏平衡产量和预计销量 8 000 件时的安全边际。(b)：讨论若降价 10% 且销量增至 9 500 件，对盈亏平衡和利润的影响。
Contribution per unit = £120 – £70 = £50. Break-even = Fixed costs / contribution per unit = £300 000 / £50 = 6 000 units. Margin of safety = 8 000 – 6 000 = 2 000 units, or 25%. This shows the sales can fall by 2 000 units before a loss is made. Students must label units correctly and express margin of safety as a percentage where asked.
单位贡献 = £120 – £70 = £50。盈亏平衡点 = 固定成本 / 单位贡献 = £300 000 / £50 = 6 000 件。安全边际 = 8 000 – 6 000 = 2 000 件，即 25%。这表明在亏损之前销量可下降 2 000 件。学生必须正确标注单位，并按题目要求将安全边际表述为百分比。
For part (b), new selling price = £120 × 0.9 = £108. New contribution = £108 – £70 = £38. New break-even = £300 000 / £38 = 7 895 units (rounded). Total profit = (9 500 × £38) – £300 000 = £361 000 – £300 000 = £61 000. The break-even rises sharply, increasing risk, but overall profit also rises because volume gain offsets the margin loss. This demonstrates that lower prices can be viable if demand is elastic enough.
第 (b) 部分，新售价 = £120 × 0.9 = £108。新贡献 = £108 – £70 = £38。新盈亏平衡 = £300 000 / £38 = 7 895 件（取整）。总利润 = (9 500 × £38) – £300 000 = £361 000 – £300 000 = £61 000。盈亏平衡点大幅上升，增加了风险，但总利润也因销量增长弥补了利润率的下降而提升。这表明如果需求弹性足够大，降价策略是可行的。
9. Financial Ratio Interpretation | 财务比率解读
The case continues with the company’s latest financials: revenue £960 000, gross profit £480 000, operating profit £180 000, current assets £250 000, current liabilities £150 000, inventory £80 000, receivables £90 000. Students must calculate and interpret the gross profit margin, operating profit margin, current ratio and acid test ratio.
案例接着给出公司最新财务数据：收入 960 000 英镑，毛利 480 000 英镑，营业利润 180 000 英镑，流动资产 250 000 英镑，流动负债 150 000 英镑，存货 80 000 英镑，应收账款 90 000 英镑。学生需计算并解读毛利率、营业利润率、流动比率和酸性测试比率。
Gross margin = (480 000 / 960 000) × 100 = 50%. Operating margin = (180 000 / 960 000) × 100 = 18.75%. Current ratio = 250 000 / 150 000 = 1.67:1. Acid test = (250 000 – 80 000) / 150 000 = 170 000 / 150 000 = 1.13:1. These indicate healthy profitability and liquidity, though comparisons with industry averages are needed for a full assessment.
毛利率 = (480 000 / 960 000) × 100 = 50%。营业利润率 = (180 000 / 960 000) × 100 = 18.75%。流动比率 = 250 000 / 150 000 = 1.67:1。酸性测试 = (250 000 – 80 000) / 150 000 = 170 000 / 150 000 = 1.13:1。这些比率表明健康的盈利能力和流动性，但进行全面评估还需要行业平均值比较。
Top answers will link ratios to the earlier investment decision. A strong liquidity position might support an expansion, but the rising break-even from the price cut suggests the business should monitor cash flow carefully. Mechanical calculation without contextual comment scores lower marks.
优秀答案会将这些比率与之前的投资决策联系起来。强劲的流动性有助于扩张计划，但降价导致盈亏平衡点上升，表明企业应密切关注现金流。只进行机械计算而不作情境评论的得分较低。
10. Essay Question: Evaluating Business Strategy | 论述题：评估企业战略
The essay question asks: “To what extent is investment appraisal the most important factor when deciding on a growth strategy?” Students must synthesize knowledge from the entire unit, drawing on NPV, decision trees, stakeholder concerns and strategic fit.
论述题问道：“在决定增长战略时，投资评估在多大程度上是最重要的因素？”学生必须综合整个单元的知识，运用净现值、决策树、利益相关者关注点以及战略匹配。
A balanced essay structure: Introduction defining investment appraisal and its role. Main body: first, arguments supporting the importance of quantitative methods (NPV provides an objective, financially rigorous benchmark; ARR and payback aid quick filtering). Then, limitations – decision trees are only as good as probability estimates; strategic fit, corporate objectives and stakeholder pressures may override numerical outcomes. For instance, a project with a borderline NPV might still be pursued if it aligns with long-term sustainability goals or satisfies powerful stakeholders like the local council.
均衡的论述结构：引言定义投资评估及其作用。正文：首先，支持定量方法重要性的论点（NPV 提供客观、财务上严谨的基准；ARR 和回收期有助于快速筛选）。然后，局限性——决策树的可靠程度取决于概率估算；战略匹配、企业目标和利益相关者压力可能优先于数值结果。例如，一个 NPV 勉强为正的项目，若契合企业的长期可持续发展目标或能取悦像地方议会这样的强有力利益相关者，仍可能被推行。
Conclusion: investment appraisal is essential for financial viability, but it must be one element within a wider decision-making framework. Students who consider opportunity costs, risk attitudes and the dynamic business environment will access the highest marks.
结论：投资评估对财务可行性至关重要，但它只能是更广泛决策框架中的一个要素。考虑到机会成本、风险态度和动态商业环境的学生将获得最高分。
