This question tests knowledge of the different sources of long-term capital available to a public company.

A debenture is a certificate acknowledging a loan made to a company, on which the company agrees to pay the lender a fixed rate of interest at agreed intervals, regardless of whether the company makes a profit or a loss. Because the interest rate is fixed and must be paid before any dividend is considered, a debenture is correctly identified as the source of capital that attracts a fixed rate of interest.

The other options do not fit this description. An ordinary share entitles its holder to a dividend that varies depending on how much profit the company makes and how much the directors decide to distribute; there is no fixed rate attached to it. A subvention is a grant or financial assistance, often from government, and it is not a loan carrying a contractual interest rate. An overdraft is a short-term banking facility that allows a company to withdraw more than it holds in its account, and while it does attract interest, it is a short-term facility rather than a long-term source of capital for a public company in the way debentures are.

Whenever a question mentions a fixed rate of interest paid regardless of profit, this points specifically to debenture holders, who rank as creditors rather than owners of the company.

This question tests knowledge of the specific functions carried out by the ports authority, as distinct from the functions of other agencies that also operate at seaports.

The ports authority is responsible for developing and running port facilities that support the movement and temporary storage of cargo passing through the port. Among its core functions is providing warehousing services, meaning it builds and manages sheds, silos, and storage areas where imported or exported goods can be kept safely while they await clearance, onward transport, or collection by owners.

The remaining options belong to other agencies rather than the ports authority. Collecting import duties and checking the activities of smugglers are functions carried out by the customs service, whose job is to assess and collect government revenue on goods crossing the border and to prevent the illegal movement of goods. Enforcing general law and order in harbours falls to the police and other security agencies operating at the port, not to the ports authority itself, whose role is essentially the commercial and operational management of port facilities.

When a question lists port-related duties, separate the ports authority's role, providing physical infrastructure and services like warehousing, berthing, and cargo handling, from the customs and security functions of duty collection, anti-smuggling checks, and policing.

Aids to trade are the services that support the smooth buying and selling of goods, removing obstacles such as distance, risk, time, and the need for finance. Insurance removes the obstacle of risk by compensating for loss or damage. Banking removes the obstacle of finance by providing loans, safekeeping of money, and payment services. Transport removes the obstacle of distance by moving goods from where they are made to where they are needed.

Production is not an aid to trade because it is the actual creation of goods and services, which is the activity that trade supports, not a service that assists trade itself. Trade begins after goods have been produced; production is a separate economic activity from the commercial services that help move and exchange those goods.

Examination reminder: aids to trade always solve a specific obstacle to buying and selling (finance, risk, distance, storage, communication); production creates the goods being traded, so it stands outside that list.

This question tests the distinction between visible and invisible items of international trade.

Visible trade involves the exchange of physical, tangible goods that can be seen, touched, and recorded as they cross a country's border, such as textiles, machinery, and oil. Invisible trade, by contrast, involves the exchange of services rather than physical items; nothing tangible crosses the border, yet money still changes hands in payment for the service rendered. Shipping is a service, the carriage of goods or passengers by sea, and because a service rather than a physical commodity is being paid for, it is classified as an invisible item of trade.

Textile, machinery, and oil are all physical commodities that can be loaded, transported, and physically delivered across borders, which makes each of them a visible item of trade rather than an invisible one. The key difference is that visible trade can be counted and recorded as actual units of goods moving through customs, while invisible trade, such as shipping, banking, insurance, and tourism, involves a service being paid for without any physical good changing hands.

Whenever a question lists a service, such as shipping, banking, or insurance, alongside physical goods, remember that the service is the invisible item, since only tangible goods count as visible trade.

Privatization is the transfer of ownership and control of a business from the government to private individuals or companies. Governments privatize enterprises such as airlines, telecommunications firms, or refineries when they want to reduce public spending, improve efficiency, or raise revenue by selling shares or assets to private investors.

The other terms describe related but different processes. Commercialisation means running a government-owned business on profit-making, commercial lines while ownership stays with the government. Deregulation means removing government rules and restrictions that control how a market or industry operates, without necessarily transferring ownership. Nationalization is the opposite of the process described in the question: it is when the government takes over ownership of a privately owned business.

Examination reminder: the key word that separates these terms is who ends up owning the business. If ownership moves from government to private hands, the answer is privatization; if it moves the other way, it is nationalization.

Bayanin Amsa

Hire purchase is a form of contract in which the buyer takes possession of goods immediately and pays for them gradually through a series of installments, while ownership of the goods only passes to the buyer after the final installment has been paid. Until that last payment is made, the goods legally still belong to the seller, even though the buyer already has and uses them.

The other terms do not match this description. Trade-in-sale involves exchanging an old item as part payment towards a new one, not paying by installments. Conditional sale is similar to hire purchase in that ownership is delayed, but under a conditional sale, the buyer agrees from the outset to eventually buy the goods outright, whereas hire purchase technically gives the buyer an option, not an obligation, to buy at the end; hire purchase remains the standard, more commonly tested term for taking possession on installment terms. Credit sale, by contrast, transfers ownership to the buyer immediately at the time of sale, even though payment is still being completed in installments, which is the opposite of what is described here.

Examination reminder: the detail that decides between hire purchase and credit sale is when ownership transfers: at the end of installments (hire purchase) or immediately at the sale (credit sale).

Bayanin Amsa

A contract is a legally binding agreement between two or more parties that is enforceable in law. For a valid contract to exist, certain essential elements must be present:

• Offer - one party proposes terms to another.
• Acceptance - the other party agrees to those terms unconditionally.
• Consideration - something of value is exchanged between the parties (money, goods, services, or a promise).
• Intention to create legal relations - both parties intend the agreement to be legally binding.
• Capacity - the parties must be legally competent (of legal age and sound mind).

An offer, acceptance, and consideration are all individual elements that together help form a contract, but none of them alone constitutes an enforceable agreement. It is only when these elements combine that a contract - an agreement enforceable in law - comes into existence.

If any essential element is missing, the agreement may be void or voidable and cannot be enforced in a court of law.

Bayanin Amsa

This question examines commercialization, which happens when a government-owned enterprise is required to operate as a profit-oriented business rather than as a subsidized public service.

Once an enterprise is commercialized, it is expected to cover its costs and generate profit from its operations instead of relying on government subsidy. To achieve this, the enterprise typically raises the amount it charges for its goods or services. From the point of view of the ordinary consumer, this means that prices of products increase, since services or goods that were previously subsidized, and therefore cheaper, now have to be paid for at a rate that reflects the true cost of production plus a profit margin.

The other statements do not correctly describe a consumer-side disadvantage of commercialization. Commercialization is generally intended to make an enterprise more efficient, not less, so it does not promote inefficiency; if anything, the pressure to be profitable tends to reduce inefficiency. It is also not primarily about worker loyalty, which relates to staff morale rather than consumer experience. Saying that customers do not have value for their money is inaccurate as a general effect, because a commercialized enterprise, aiming for profit and customer retention, usually has an incentive to maintain or improve the quality of what it offers even as prices rise.

When a question asks about the effect of commercialization on the buying public specifically, focus on the direct financial impact, higher prices, rather than internal organizational effects like staff morale or efficiency.

Trade is the direct buying and selling of goods, but it needs supporting services such as transport, banking, insurance, warehousing, and advertising to actually move goods from producers to consumers efficiently. The single word that covers both trade and all these supporting services together is commerce.

All activities concerned with the distribution and exchange of goods and services, including the aids to trade that make buying and selling possible, are referred to as commerce. Trade is only one part of commerce, not the whole of it, so a term wider than trade is needed here.

A market survey is a narrow research activity that studies customer needs or preferences, and advertising is one single aid to trade that promotes goods; neither of these is broad enough to cover the entire range of distribution and exchange activities described in the question. Trade itself only covers buying and selling, leaving out the aids to trade that the question is also referring to.

Keep the hierarchy clear: trade is buying and selling, aids to trade support that buying and selling, and commerce is the umbrella term covering both together.

Bayanin Amsa

Marine insurance can be arranged to cover different interests connected with a sea voyage: the vessel itself, the goods it carries, or the risks of the specific journey. Each of these can be insured separately, so it matters exactly which interest a particular policy protects.

A policy that covers only the physical structure of the vessel, that is, the ship's hull and machinery, against loss or damage is called hull insurance. It protects the ship owner's investment in the vessel itself, not the goods being transported.

Cargo insurance instead protects the goods being carried on the ship, which is a different interest from the vessel. Voyage insurance and haulage insurance are broader or unrelated terms that do not specifically single out the ship's own body as the object of cover.

When a marine insurance question specifically mentions "the ship itself" or "the body of the vessel," the correct term to reach for is hull insurance, as distinct from cargo insurance for the goods on board.

Bayanin Amsa

This question tests knowledge of consumer protection law and its purpose within commerce.

Legislation aimed at protecting consumers is designed to prevent sellers from misleading buyers about the goods and services they offer, for example by giving a false description of the quantity, quality, fitness, or origin of a product. The Trade Description Act exists specifically for this purpose; it makes it an offence for a trader to apply a false or misleading description to goods that are being sold, giving buyers legal protection against deception.

The other pieces of legislation regulate different areas of commercial life. The Partnership Act governs the formation, rights, and duties of partners running a business together, not the protection of the people who buy from that business. The Law of Contract sets out the general rules for when an agreement becomes legally binding between any two parties, and it is not focused specifically on consumers. The Company's Act regulates the formation, registration, and internal governance of companies, again without a specific consumer protection focus.

When a question asks specifically about protecting buyers from false claims about goods, look for legislation with "trade description" or similar consumer-facing wording in its name, rather than laws that govern how businesses are formed or structured internally.

Bayanin Amsa

This question is testing knowledge of the functions of management, which include planning, organizing, staffing, directing, and controlling.

The management function that specifically involves recruiting, selecting, training, and assigning employees to the positions that best suit their skills is called staffing. It is the process of ensuring that the right people occupy the right roles within the organization, so that each job is performed by someone with the appropriate qualification and ability.

The remaining options describe other management functions. Planning involves setting the organization's objectives and deciding in advance the actions needed to achieve them, before any positions are filled. Directing involves guiding, supervising, and instructing employees who are already in their roles so that they carry out their tasks properly. Motivating is the act of encouraging and inspiring employees to perform well, which happens after staffing has placed them in their jobs.

Whenever a question mentions matching people to positions based on suitability, the correct management function is staffing, not directing or planning, which deal with instruction and goal-setting rather than placement.

Bayanin Amsa

Goods traded in an economy are grouped according to who uses them next. A producer good (also called a capital good) is one used by a business to make other goods or services, such as machinery, raw materials, or tools. A consumer good is one that goes directly to the final user for personal satisfaction, such as food, clothing, or furniture. Because every good produced in an economy ends up either feeding into further production or being consumed directly by households, this producer-and-consumer split is the standard broad classification used in commerce.

The other groupings mentioned are narrower distinctions within consumer goods rather than the general classification of all goods. Saleable and non-saleable goods is not a recognised commerce classification. Inferior and superior goods describes how demand for a good changes with income, and luxurious and essential goods describes how necessary a good is to a consumer; both apply only within the consumer-goods category, not to goods as a whole.

Examination reminder: when a question asks for the broadest way goods are classified, look for the option that could include every type of good in the economy, not one that only describes a subset of consumer goods.

Bayanin Amsa

When shares are sold, the seller and buyer must agree on whether the buyer or the seller keeps the right to the next dividend payment. A share sold cum div (Latin for 'with dividend') is priced so that the buyer, as the new owner, will receive the upcoming, already-declared dividend when it is paid out. The price of a cum div share is therefore slightly higher than it would otherwise be, because it includes the value of that pending dividend.

The opposite situation is described by ex-div, where the share is sold without the right to the next dividend, meaning the original seller keeps that payment instead. A share sold at par describes a share sold at its original face value, and a share sold at a discount describes one sold below its face value; neither of these terms relates to who receives a pending dividend.

Examination reminder: remember that 'cum' means 'with' in Latin, so cum div literally means the buyer receives the dividend with the share purchase.

Bayanin Amsa

The cost of goods sold represents the total amount spent to get an item ready for sale, which includes both the price paid to acquire it and any further cost needed to make it saleable, such as repair or reconditioning.

1. Purchase price of the bicycle: \( \text{₦}20{,}000 \)
2. Repair cost: \( \text{₦}5{,}000 \)
3. Cost of goods sold: \( \text{₦}20{,}000 + \text{₦}5{,}000 = \text{₦}25{,}000 \)

Because the bicycle could not have been resold profitably without the repair, the repair cost is treated as part of what it took to bring the goods to a saleable condition, so it is added to the purchase price to give a total cost of goods sold of \( \text{₦}25{,}000 \).

Taking only the purchase price of \( \text{₦}20{,}000 \) ignores the repair cost that was necessary before sale, while using the selling price of \( \text{₦}30{,}000 \) confuses revenue with cost; these two figures answer different questions from the one asked here.

Whenever a question describes an item bought and then improved or repaired before sale, add the improvement cost to the purchase price to find the true cost of goods sold.

Bayanin Amsa

"Cash with order" is a term of sale in which a buyer must pay for goods at the same time as placing the order, before the seller dispatches anything. Because payment happens before any goods move, the seller needs a document that quotes the price and terms of the goods so the buyer knows exactly what to pay, without that document being a demand for money already owed.

A document that lists the goods, their prices, and the terms of the intended sale, sent to a buyer before an actual transaction is concluded, is a proforma invoice. It allows the buyer to see the cost, agree to it, and send payment along with the order, which fits the cash-with-order arrangement.

A debit note and a credit note are both used after a sale has already been made, to correct undercharges or overcharges on an invoice already issued. A consignment note is a transport document that accompanies goods sent to an agent for sale on the owner's behalf, and it has nothing to do with upfront payment. None of these fits a situation where money must be sent before the goods are even ordered in the seller's records.

When you see "before the sale is finalised" in a commerce question about documents, think proforma invoice; once the sale is done, the relevant documents become invoices, debit notes, or credit notes.

Bayanin Amsa

This question is testing an understanding of how banks protect themselves when granting a loan.

When a bank lends money, it usually asks the borrower to pledge something valuable that the bank can hold or claim if the borrower fails to repay the loan. This item is called a collateral security. In this case, Mr Ojo deposited his life insurance certificate with the bank as the item of value backing the N54,000 loan; if he defaults on repayment, the bank has a legal claim against the value of that certificate.

The certificate cannot be a current asset of the bank, because a current asset is something the bank already owns and expects to convert to cash in its normal course of business; the certificate still belongs to Mr Ojo and is only held as security. It is not an interest charged, because interest is the cost of borrowing the money, expressed as an amount or percentage, not a physical document. It is also not a loan repayment, since repayment refers to Mr Ojo paying back the borrowed sum over time, which is a separate matter from the certificate deposited at the start of the loan.

Whenever a question describes an item pledged to secure a loan, rather than the loan amount, the interest, or the repayment itself, the correct term is collateral security.

Bayanin Amsa

Forming a public limited company involves more than one certificate. A Certificate of Incorporation is issued first, and it confirms that the company legally exists as a separate entity. However, a public company cannot start trading or borrowing money purely on the strength of that certificate.

Before a public company can commence business, the registrar of companies must issue a further document, the trading certificate, once the company has satisfied additional requirements such as showing that it has raised the minimum amount of share capital required by law. This certificate is the specific authorisation to begin trading.

It is easy to confuse this with the Certificate of Incorporation because both are issued by the registrar and both sound like permissions. The distinction matters: incorporation creates the company as a legal person, while the trading certificate permits that already-existing company to actually start operating. Memorandum and Article of Association are internal constitutional documents drawn up by the company itself, not certificates issued by the registrar to permit trading.

Exam takeaway: for a public limited company, incorporation and permission to trade are two separate steps, each marked by its own certificate.

Bayanin Amsa

This question tests knowledge of the different forms of business combination and the specific purpose each one serves.

When independent producers of similar goods agree to work together specifically to control how much is produced, with the deliberate goal of keeping prices at a level they choose, this arrangement is called a cartel. Members of a cartel remain independent businesses, but they coordinate output levels so that supply stays low enough to keep prices fixed at an agreed rate.

The other terms describe different arrangements. A trust involves firms being combined more completely, often under common ownership or control, usually to eliminate competition altogether rather than simply to fix prices while remaining separate. A syndicate is a group of firms or individuals that combine temporarily, often to finance or carry out a large project such as underwriting a big loan or issue. A consortium is likewise a temporary joint venture formed by independent firms for a specific project, without the ongoing price-fixing intention that defines a cartel.

The defining clue in this question is the explicit intention to fix price while controlling output; whenever both of those elements appear together, the correct term is cartel.

Bayanin Amsa

Turnover refers to the total value of sales a business makes within a given period, usually a year. It measures how much revenue passes through the business from selling its goods or services, before any costs are deducted.

Turnover is different from the other terms. Purchases are the goods or raw materials the business buys in, which is the opposite side of the trading activity from sales. Assets are the resources the business owns, such as equipment, stock, or cash, and reflect what the business has at a point in time rather than what it has sold. Profit is what remains after all costs and expenses have been subtracted from sales revenue, so a business can have a high turnover but low or even negative profit if its costs are high.

Examination reminder: do not confuse turnover with profit. Turnover is the total sales figure; profit is turnover minus costs.

Bayanin Amsa

On a stock exchange, an option contract gives its holder the right, but not the obligation, to buy or sell a stated quantity of shares at a fixed price within a set period. There are two basic types, distinguished by which right they grant.

A put option grants the holder the right to sell shares at the agreed price. The holder buys this right hoping the market price will fall, so they can sell at the higher, pre-agreed price and profit from the difference. This is the opposite of a call option, which grants the right to buy.

A frequent confusion is assuming every option is about buying, since buying shares is the more familiar transaction to beginners. Remembering the pairing helps: a call is linked to buying, and a put is linked to selling shares onto the market.

Exam takeaway: whenever a question names put or call in the context of options, immediately map put to the right to sell and call to the right to buy.

Bayanin Amsa

This question tests the distinction between pre-sale services, which happen before a purchase is completed, and after-sale (post-sale) services, which happen once the customer already owns the product.

Pre-sale services are activities carried out to help a customer decide whether to buy something and to prepare the product for sale. Demonstrating how a product works, providing detailed information about the goods, and setting up storage facilities so items are ready and available for customers to inspect and buy are all things that happen before a purchase is made.

Repair and maintenance work is different: it is carried out on a product that a customer has already bought and is now using, to keep it functioning properly or to fix a fault. Because it takes place after ownership has changed hands, repair and maintenance work is an after-sale service, not a pre-sale service, which makes it the option that does not belong with the other three.

When classifying a customer service activity, ask whether it happens before the customer commits to buying (pre-sale) or after the customer already owns the product (after-sale); repair and maintenance always falls into the after-sale category.

Bayanin Amsa

A means of payment is a document or instrument that can be used directly to settle a debt or transfer money. A postal order is bought from the post office for a specific amount and can be cashed or paid into an account by the person named on it, making it a direct method of paying someone, especially useful for sending money by post.

The other items are not means of payment in themselves. C.I.F (Cost, Insurance, and Freight) is a shipping term that states who bears the cost and risk for goods during transport in international trade; it is a term describing trade conditions, not a payment instrument. An I.O.U is simply an informal written acknowledgement that money is owed; it does not transfer money and cannot be used to settle a debt with a third party. A promissory note is a written promise to pay a sum of money at a future date, so it represents a deferred obligation rather than an immediate means of payment.

Examination reminder: a true means of payment must be usable right away to move money or settle a debt; a mere promise or acknowledgement of debt does not qualify.

Bayanin Amsa

This question tests knowledge of the comparative advantages of different modes of transport used in commerce.

Rail transport is able to carry very large and bulky loads in a single trip using wagons linked together, which spreads the running cost of the journey over a much greater quantity of goods. This is what makes the cost per unit of goods carried by rail relatively low compared with the other common modes, especially over long distances and for heavy or bulky commodities.

Air transport is the fastest mode available, but it is also the most expensive because of high fuel consumption and limited cargo capacity relative to cost, making its cost per unit high rather than low. Road transport offers flexibility and door-to-door delivery, but vehicles can only carry comparatively small loads at a time, so the cost per unit tends to be higher than rail for large-scale movement of goods, especially over long distances. Pipeline transport is very efficient, but it is restricted to liquids and gases, such as crude oil or water, and cannot be used to convey ordinary manufactured or general goods at all.

When a question asks which mode of transport is generally cheapest per unit for moving large quantities of goods, rail is the standard answer because of the economies of scale that come from moving many wagon-loads together.

Bayanin Amsa

This question tests knowledge of the recognized principles that govern insurance contracts, which are insurable interest, utmost good faith, indemnity, subrogation, contribution, and proximate cause.

Each of these principles has a specific meaning. Insurable interest requires that the person taking out a policy will suffer a genuine financial loss if the insured event occurs. Indemnity means the insured should be restored to the same financial position they were in before the loss, no more and no less. Subrogation allows the insurer, after paying a claim, to take over the insured's right to recover the loss from any third party responsible for it.

"Insurable risk" is not one of the formally recognized principles of insurance; it is simply a general description of a risk that is capable of being insured, rather than a rule that governs how an insurance contract operates or how claims are settled. Because it does not describe an operating principle of insurance in the way that indemnity, subrogation, and insurable interest do, it is the term that does not belong among the principles of insurance.

When a list mixes formally named principles with a general descriptive phrase, the descriptive phrase, one that only labels a category rather than a rule governing the contract, is usually the option that is not a true principle.

Bayanin Amsa

This question tests the calculation of working capital, which measures a business's short-term financial health.

Working capital is found using the formula:

From the figures given, the current assets are the items a business expects to turn into cash within a year: debtors, cash in hand, and the closing stock (the stock actually on hand at the end of the period, not the opening stock, which belonged to the earlier period and has already been used up or sold). The current liabilities are the short-term debts owed: creditors and the bank overdraft.

Applying the formula:

The working capital is therefore #5,000.00. Sales, opening stock, and purchases are figures used in preparing the trading account to find gross profit; they are not part of the working capital calculation, which only uses balance-sheet items, current assets and current liabilities, at the end of the period.

When solving working capital questions, always use closing stock, never opening stock, and exclude trading account items like sales and purchases from the calculation.

Bayanin Amsa

Current assets are resources a business expects to convert into cash, sell, or use up within a normal trading period, usually one year. They are separated from current liabilities, which are amounts the business owes and must pay out in the near future.

Cash is the most liquid current asset of all, and trade debtors are customers who owe the business money for goods bought on credit, which the business expects to collect as cash soon. Both of these belong on the assets side of the balance sheet, so cash and trade debtors together are correctly classified as current assets.

Trade creditors are suppliers the business owes money to, so they are a current liability, not an asset; any option that mixes trade creditors in with cash or trade debtors incorrectly combines an asset with a liability. That rules out grouping trade debtors, trade creditors and cash together, cash and trade creditors together, or trade creditors and trade debtors together.

A reliable check for this kind of question is to ask whether the business is owed money or owes money: debtors and cash are owed to or held by the business, so they are assets, while creditors are owed to others, so they are liabilities.

Bayanin Amsa

Producers use several distinct techniques to help their goods sell well. Labelling attaches information about a product, such as its ingredients or usage instructions, and branding gives a product a distinctive name or symbol that sets it apart from competitors' goods.

The activity of wrapping or containing goods so that they become attractive to look at and convenient to carry, store, and use is packaging. Good packaging protects the product while also making it more appealing and easier to handle from the factory through to the final consumer.

Labelling only supplies information rather than physically making a product easier to handle, and branding is about identity and recognition rather than physical attractiveness or ease of handling. Merchandising covers the broader in-store presentation and promotion of goods, but it is not the specific act of making an individual product's container attractive and manageable.

When a question focuses on a good's container being attractive and easy to handle, the term being tested is packaging, distinct from the informational role of labelling or the identity role of branding.

Bayanin Amsa

This question tests knowledge of the elements that can affect whether a contract is validly and fairly formed.

When one party makes a statement that is not true, and does so with the aim of persuading the other party to enter into a contract, that false statement is called misrepresentation. It induces the other party to agree to the contract on the basis of information that does not reflect the true facts, and depending on whether the false statement was made knowingly or carelessly, it may make the resulting contract voidable.

The other terms describe different requirements for a valid contract. Consensus ad idem refers to both parties genuinely agreeing to the same terms, a meeting of minds, which is a general requirement for any contract rather than a description of a false inducing statement. Legal capacity refers to whether a party is legally allowed to enter into a contract at all, for example being of sound mind and of contractual age, which has nothing to do with the truth of any statement made. Consideration is the value, money, goods, or a promise, that each party gives in exchange for the other's promise, and it is unrelated to whether a statement made during negotiation was true or false.

Whenever a question describes a false statement used specifically to induce someone into a contract, the correct term is misrepresentation, not the general contract requirements of agreement, capacity, or consideration.

On a stock or commodity exchange, settlement day is the fixed date on which a speculator who has bought or sold on account must complete payment or delivery. Sometimes a speculator who has bought shares is not yet ready to pay and settle, perhaps because they are still waiting for the price to move in their favour, so they ask for the settlement to be carried over to the next settlement day.

The charge paid by that speculator to postpone settlement to the next account is called contango. It is essentially a fee for the privilege of delaying payment while still holding the position.

Backwardation is the reverse charge, paid by a seller who wants to delay delivering shares they have sold. Brokerage and commission are fees paid to the broker for arranging the transaction itself, not for delaying settlement, so they do not match what the question describes.

Keep the two terms apart by remembering who pays: a buyer delaying payment pays contango, while a seller delaying delivery pays backwardation.

Bayanin Amsa

Services are classified as direct or indirect based on who benefits from them. A direct service benefits the specific individual who requests and pays for it, such as a doctor treating a private patient. An indirect service benefits the whole community or society generally, rather than one identifiable paying customer. The police keeping law and order protect everyone in society collectively, not a single paying client, which is why this is an indirect service.

The other options do not fit this situation. A self-service is one a person performs for themselves, such as cooking their own meal, which does not describe the police's role. A commercial service is one provided for profit in a business transaction between a specific provider and a paying customer, but policing is a public function funded by the state for the benefit of the whole society, not a profit-making commercial exchange.

Examination reminder: to tell direct and indirect services apart, ask who directly benefits: one identifiable person (direct) or society as a whole (indirect).

Bayanin Amsa

This question tests understanding of the nature of the relationship between an agent and a principal, using the specific case of an agent of necessity.

An agent of necessity is someone who, faced with an emergency, acts on behalf of a principal to protect the principal's property or interests even without prior instruction to do so, for example a carrier who sells perishable goods that would otherwise spoil in transit. Because the agent is acting without direct supervision and without a fresh, specific instruction covering the emergency, the principal has to rely entirely on the agent to act honestly and in the principal's best interest. This is why the duty of an agent of necessity to the principal is based on trust: the principal trusts the agent to use good judgment and act faithfully even when circumstances have not been explicitly negotiated or agreed in advance.

Negotiation and mutual agreement describe how ordinary contracts or instructions are normally settled between two parties, but an agent of necessity typically has to act before there is time for any negotiation or fresh agreement with the principal. Ability refers to the agent's competence or skill in carrying out a task, which is important but is not what the duty owed to the principal is founded on; the duty exists because the principal is placing confidence in the agent, not merely because the agent is capable.

Whenever a question describes an agent acting on behalf of someone without direct instruction, remember that this kind of relationship rests on trust, since the principal cannot supervise or negotiate every action in real time.

Employers' liability insurance covers an employer against claims made by employees who are injured or made ill while carrying out their work. It compensates staff for injuries sustained in the workplace and protects the employer from having to pay large sums out of pocket if found legally responsible for the accident.

The other types of insurance cover different risks. Fidelity guarantee insurance protects an employer against financial loss caused by the dishonesty of an employee, such as theft or fraud, not physical injury. Consequential loss insurance covers the loss of profit or extra expenses a business suffers as an indirect result of an insured event, such as a fire stopping production. Products liability insurance covers claims made by customers who are harmed by a faulty product the business made or sold, not by employees injured at work.

Examination reminder: match the claimant to the right policy: employees injured at work claim under employers' liability insurance, while customers harmed by a product claim under products liability insurance.

Bayanin Amsa

This question tests knowledge of basic retail pricing terms used in commerce.

When a seller buys an article and later sells it for more than it cost, the amount added on top of the cost price to arrive at the selling price is known as mark-up. It represents the profit margin the seller builds into the selling price, and it can be expressed either as a naira amount or as a percentage of the cost price.

The other options describe different pricing concepts. A rebate is a partial refund given to a buyer after a purchase, often as an incentive or adjustment, and is not simply the gap between cost price and selling price. A discount is a reduction made to the normal selling price at the point of sale, for example for bulk buying or prompt payment, rather than the amount added above the cost price. A commission is a payment made to an agent or salesperson for a service, usually a percentage of the value of a sale, and it is unrelated to the difference between what an item cost the seller and what it is sold for.

Whenever a question asks about the gap between cost price and selling price specifically, the correct term is mark-up, not a reduction, refund, or agent's fee.

Insurance companies must charge policyholders a fair price, called a premium, for the cover they provide. Setting that price correctly requires statistical calculations based on the probability of a loss occurring, such as the chance of death, fire, or accident, and the likely size of any claim.

The professional trained in these statistical and mathematical calculations, who determines premiums and reserves for an insurance company, is an actuary. Their work ensures the company charges enough in premiums to cover expected claims while remaining fair to customers.

An assessor evaluates the value of a loss after a claim is made, an underwriter decides whether to accept a particular risk and on what terms, and a broker acts as a middleman who helps clients find suitable insurance. None of these roles is specifically responsible for the statistical calculation of premiums, which is the actuary's specialised task.

Keep the roles distinct: the actuary calculates premiums using statistics, the underwriter accepts or rejects risk, and the assessor values claims after a loss.

In shipping, a charterer who hires a ship agrees to pay for the space on board, and problems can arise either when the charterer fails to provide enough cargo to fill that space, or when the ship is delayed at port beyond the agreed loading or unloading time.

When a charterer does not supply enough cargo to fill the space they hired on a ship, they must still pay the ship owner for the unused space, and this charge is called dead freight. It compensates the ship owner for revenue lost because part of the ship's capacity was booked but left empty.

Demurrage is charged when a ship is kept waiting at port beyond the agreed time, which is a delay charge rather than a charge for unused cargo space. Dock dues are fees paid for using port facilities, and a penalty is a general term for a punitive charge, neither of which specifically describes payment for unused ship space.

Distinguish the two shipping charges this way: dead freight is for space booked but not filled with cargo, while demurrage is for time lost through delay at port.

A contract is an agreement between two or more parties that the law will enforce, meaning that if one party fails to keep their promise, the other can take legal action to obtain a remedy such as compensation or performance. For an agreement to become a contract, it must generally contain several elements, including an offer, acceptance of that offer, and consideration (something of value exchanged by each side), along with the intention to create legal relations.

The other terms name only individual building blocks of a contract, not the finished, enforceable agreement itself. An offer is merely a proposal made by one party. A consideration is the value each party gives or promises to give. An acceptance is simply the agreement to the terms of an offer. None of these alone amounts to a legally enforceable agreement; they must combine, along with other requirements, to form a contract.

Examination reminder: think of offer, acceptance, and consideration as ingredients; the contract is the finished, legally binding agreement that results once these ingredients are properly combined.

A proforma invoice is sent by a supplier before any sale on credit takes place. It looks like a normal invoice, listing the goods, prices, and total cost, but it is not a demand for payment on credit terms. Instead, it asks the buyer to pay in advance or on delivery, which is exactly what a supplier does when they are unwilling to extend credit to a customer.

The other documents serve different purposes. A consular invoice is a document certified by the consulate of the importing country, used mainly for customs and import-duty purposes in international trade. A quotation simply states the price at which a supplier is willing to sell, without necessarily addressing credit terms. An advice note tells the buyer that goods are on their way, listing what has been dispatched, and is normally used alongside an ordinary invoice, not as a substitute for one.

Examination reminder: the defining feature of a proforma invoice is that it demands payment before or on delivery, which is why it is the supplier's tool for avoiding credit sales.

A counter offer is a new offer made in response to an original offer, usually changing one or more of its terms, such as the price or quantity. Making a counter offer automatically cancels or terminates the original offer, because it is treated in law as a rejection of that offer combined with a fresh proposal of the counter offer's own terms. The original offeror is no longer bound by their first offer once a counter offer has been made; they must decide whether to accept the new terms instead.

The other terms do not describe this situation. An invalid offer is one that fails to meet the legal requirements of a valid offer from the start, rather than one terminated by a later response. A void contract is an agreement that has no legal effect at all, which is a different concept from an offer being replaced before any contract is even formed. A quasi contract is an obligation the law imposes even though no real contract exists, again unrelated to the process of offer and counter offer.

Examination reminder: remember that a counter offer does two things at once: it kills the original offer and creates a brand new one that the original offeror can accept or reject.

Contribution is the insurance principle that applies when more than one insurer covers the same risk for the same insured item, and a loss occurs. Under this principle, the insurers share the cost of the claim between themselves, in proportion to the amount each has insured, so that the policyholder is compensated fully but does not profit by claiming the full loss from each insurer separately. Since Greene and Sunwar Insurance Companies jointly indemnified Fatou for the same storey building, they must have shared the payout between them according to this principle.

The other principles describe different situations. Subrogation allows an insurer who has already paid a claim to take over the insured's right to claim against a third party responsible for the loss. Proximate cause is used to identify the dominant cause of a loss to decide whether the policy actually covers it. Insurable interest requires that the person taking out the policy would suffer a genuine financial loss from the event insured against; it does not deal with how multiple insurers share a payout.

Examination reminder: contribution only comes into play when two or more insurers cover the identical risk on the identical property; without that overlap, there is nothing to share.
