JAMB Commerce 2025 Past Questions & Answers

Goods are fundamentally classified into producer and consumer goods based on their end-use. Producer goods are used in the production of other goods and services, while consumer goods are bought for direct consumption to satisfy human wants. This classification is essential for understanding the flow of goods in an economy and is directly related to the concept of production.

Common mistake: Students might choose 'luxurious and essential goods' as these are also classifications, but 'producer and consumer goods' represents a more fundamental and broad classification based on the role of the goods in the production and consumption process.

Privatization is the process of transferring the ownership of a business from the government (public sector) to private individuals or companies. The question describes this exact scenario, where a government-owned business is sold to individuals. This is often done to improve efficiency and encourage competition.

Common mistake: Students often confuse privatization with commercialisation, but commercialisation means making a government company operate for profit while the government still owns it.

Poundage is the official term for the commission or fee charged by the post office for issuing a postal order. This fee covers the administrative cost of providing the money transfer service. When you buy a postal order to send money, you pay the face value of the order plus the poundage.

Common mistake: Students may mistakenly choose 'interest' because the transaction involves money, but interest is a charge for borrowing money, not a fixed fee for a money transfer service.

An open cheque is a type of cheque that can be cashed directly over the counter at the bank by the person presenting it, without needing to be deposited into an account first. This makes it a convenient way to get immediate cash. Unlike a crossed cheque, it does not require the money to be paid into a bank account.

Common mistake: Students might mistakenly choose option B or C, thinking an 'open' cheque implies missing details, but an open cheque still requires a payee name and a specific amount to be valid.

A proforma invoice is a preliminary bill of sale sent to a buyer before the goods are shipped or payment is made. It outlines the goods, quantity, and price, and is often used when a supplier requires payment upfront or does not wish to extend credit to the buyer. This document serves as an offer to sell under specific terms, including payment conditions.

Common mistake: Students might mistakenly choose 'Quotation' because it also offers goods at a price, but a proforma invoice is more formal and specifically addresses the terms of sale, often implying upfront payment or no credit.

Aids to trade are services that facilitate the buying and selling of goods and services, making trade easier and more efficient. Examples include insurance, banking, and transportation, which help manage risks, payments, and movement of goods. Production, on the other hand, is the process of creating goods and services, which happens before trade can even take place. Therefore, production is a primary economic activity, not an aid that facilitates trade.

Common mistake: Students often confuse production with aids to trade because it's a crucial part of the overall economic process, failing to distinguish between the creation of goods and the services that help move or exchange them.

A postal order is a financial instrument purchased from a post office that allows a person to send a specific amount of money to someone else. The recipient can then exchange the postal order for cash at their local post office, making it a valid means of payment. The other options are not direct payment methods; an I.O.U and a promissory note are promises to pay later, while C.I.F is a shipping term in foreign trade.

Common mistake: Students often mistakenly choose 'Promissory note' because it is a financial document, but it is a credit instrument that promises future payment, not an immediate means of payment.

Turnover in business refers to the total value of sales generated by a company over a specific period, usually a year. It represents the total revenue earned from selling goods or services before any expenses are deducted. Therefore, turnover is synonymous with the sales of the business.

Common mistake: Students often confuse turnover with profit, but profit is what is left after all costs and expenses have been subtracted from the turnover (sales).

Devaluation is the deliberate decision by a country's government or central bank to reduce the official value of its currency compared to other currencies. This means you would need more of your country's money (e.g., Naira) to buy the same amount of a foreign currency (e.g., US Dollar). This policy is often used to make the country's exports cheaper for foreigners to buy and make imports more expensive for its own citizens, which can help correct a trade deficit.

Common mistake: Students often mistakenly choose inflation, but inflation refers to the decrease in the purchasing power of a currency *within* its own country, not its value relative to foreign currencies.

The principle of insurable interest means that a person can only insure something if they would suffer a financial loss should that thing be damaged or lost. For example, you can insure your own car but not your neighbour's, because you would not lose money if your neighbour's car was damaged. This principle ensures that insurance is not used for gambling.

Common mistake: Students might choose 'indemnity' because it also relates to financial loss, but indemnity ensures you are compensated for the actual loss, while insurable interest determines if you have the right to insure in the first place.

The exchange of goods for goods in international trade is specifically known as counter trade. This is a form of foreign trade where payment is made with goods or services instead of money. It falls under the broader umbrella of foreign trade practices and can impact a country's balance of payments.

Common mistake: Students might mistakenly choose 'Visible trade' which refers to the trade of physical goods, but doesn't specify the goods-for-goods exchange method, or 'Smuggling' which is illegal trade.

One of the biggest advantages small retailers have is the personal connection they build with their customers. They often know their customers by name, understand their needs, and can offer services like selling on credit. This creates strong customer loyalty, which helps them survive against the competition from larger, less personal stores.

Common mistake: Students might choose option A because it is a true characteristic of many small businesses, but it is a financial weakness, not a reason for their survival against competition.

An insurance company, stock exchange, and clearing house are all types of financial institutions as they deal with money, investments, and financial transactions. A commodity board, however, is typically a government agency that regulates and promotes the production and marketing of specific commodities, not primarily a financial institution. Therefore, it is the correct answer.

Common mistake: Students often confuse a commodity board with a commodity exchange, which is a financial market, leading them to incorrectly assume the board is also a financial institution.

Trade is the fundamental economic activity that involves the exchange of goods and services between parties. This exchange is primarily characterized by the act of buying and selling. It is a core component of commerce, facilitating the movement of products from producers to consumers.

Common mistake: Students might choose 'distribution of goods' (A) because trade involves distribution, but 'buying and selling' (C) is a more comprehensive and accurate description of the core activity of trade itself.

The job of the police in maintaining law and order is considered an indirect service because it benefits the entire society by creating a safe and stable environment, rather than directly serving individual customers for a fee. These services are usually funded by taxes and contribute to the general welfare. This contrasts with direct services, which are provided specifically to an individual who requests and often pays for them.

Common mistake: Students might mistakenly choose 'commercial services' if they think any paid job is commercial, or 'direct service' if they focus on individual police interactions rather than the broader societal benefit.

The term 'cum div' is short for 'with dividend'. When a share is sold cum div, it means the price includes the right for the new buyer to receive the next dividend that is about to be paid out by the company. Therefore, the buyer of the share will get the pending dividend.

Common mistake: Students often confuse 'cum div' with its opposite, 'ex-div', which means the seller keeps the upcoming dividend and the share is sold 'without dividend'.

A contract is terminated by frustration when an unforeseen event, which is not the fault of either party, makes it impossible to carry out the agreement. In this case, the theft of the cows was an unexpected event that made it impossible for Musa to supply them to Aro. Since neither party was at fault, the contract is legally ended due to frustration.

Common mistake: Students often mistakenly choose 'breach' because the contract was not completed, but they forget that a breach implies one party is at fault, whereas frustration occurs due to an unforeseen event beyond anyone's control.

A contract is the correct answer because, by definition, it is an agreement between two or more parties that the law will enforce. For an agreement to become a contract, it must have key elements like an offer, acceptance, and consideration. These elements make the agreement legally binding, meaning if one person breaks their promise, the other can seek a remedy in court.

Common mistake: Students may mistakenly choose 'offer' or 'acceptance' because they are essential parts of forming an agreement, but they are just individual steps and not the complete, legally enforceable agreement itself.

The certificate of incorporation is the legal document that officially creates a company and gives it a separate legal identity. For a public company, receiving this certificate is the primary step that proves it has been legally formed. While a public company also needs a 'Certificate of Trading' to actually begin operations, the certificate of incorporation is the foundational approval that allows it to proceed towards starting its business.

Common mistake: Students often mistakenly choose option A because the certificate of incorporation does establish the company as a separate legal entity, but option D better describes the implication for the company's next stage, which is commencing business.

Employers' liability insurance is a policy that protects a business against claims from employees who get injured or fall sick because of their job. This insurance covers the compensation costs that the employer is legally required to pay to the injured staff. It is specifically designed for situations where staff are harmed while at work.

Common mistake: Students may mistakenly choose Fidelity guarantee insurance because it also involves the employer and employee, but this insurance covers financial loss from an employee's dishonesty, not physical injury at work.

The principle of contribution in insurance applies when an insured person has taken out multiple policies for the same risk with different insurers. In such cases, if a loss occurs, all the insurers contribute proportionally to indemnify the insured, ensuring they do not receive more than the actual loss. This prevents the insured from profiting from the loss.

Common mistake: Students often confuse contribution with subrogation, which is when the insurer, after paying a claim, takes over the insured's right to recover from a third party responsible for the loss.

A sole proprietorship is owned and managed by one person. Sources of capital for such a business typically include the owner's personal savings, loans from family or friends, or bank loans. Issuing debentures or shares are methods of raising capital used by limited liability companies, not sole proprietorships. Admitting a new member would change the business structure from a sole proprietorship to a partnership.

Common mistake: Students might mistakenly choose 'Issue of shares' or 'Issue of debenture' because they are common capital sources, but these are only applicable to limited liability companies, not sole proprietorships.

The question describes a method of acquiring goods where payment is made over time in installments, and possession is granted before full ownership. This is the definition of hire purchase, which is a specific term or condition under which goods are bought and sold. Therefore, it fits perfectly under the 'Purchase and sale of goods (documents and terms)' subtopic.

Common mistake: Students often confuse hire purchase with 'credit sale' (option D) because both involve deferred payments, but in a credit sale, ownership transfers immediately, unlike hire purchase.

Comparative cost advantage is the main theory explaining why international trade occurs. It states that a country should specialize in producing and exporting goods that it can make at a lower opportunity cost compared to other countries. This allows all trading nations to benefit from specialization and increased overall output, even if one country is more efficient at producing everything.

Common mistake: Students often confuse comparative cost advantage with absolute cost advantage, which is a simpler theory that doesn't account for opportunity cost.

A counter offer is a new offer made in response to an initial offer, which effectively rejects and terminates the original offer. For example, if someone offers to sell a phone for N10,000 and you offer N8,000, your N8,000 offer is a counter offer. This means the original N10,000 offer is no longer valid.

Common mistake: Students might choose 'an invalid offer' if they don't understand that a counter offer is a specific legal term that creates a new offer while simultaneously rejecting the previous one.
