JAMB Commerce 2010 Past Questions & Answers

The wealth of a nation is determined by the total value of all goods and services it produces and exchanges. Commercial activities cover all these processes, including trade (buying and selling) and all the aids to trade like banking, transport, and insurance. Therefore, a high volume of commercial activities leads to greater national wealth.

Common mistake: Students might mistakenly choose 'bilateral trade activities' or 'multilateral trade activities' because foreign trade is important, but they overlook that 'commercial activities' is a broader term that includes both domestic and foreign trade.

Skilled labour refers to workers who possess special knowledge, expertise, and abilities, which are typically acquired through formal education and practical training. Unskilled labour, on the other hand, involves tasks that do not require specialized training or a high level of education. Therefore, the level of education and training is the primary way to distinguish between the two types of labour.

Common mistake: Students often mistakenly choose 'salaries and wages' because skilled workers usually earn more, but this is a consequence of their skill, not the defining factor used for classification.

This question tests the understanding of different types of services as occupations. A direct service is a personal service rendered directly by the provider to the final consumer. Since the doctor is personally attending to the patient, he is providing a direct service, making him a direct service worker.

Common mistake: Students might mistakenly choose 'indirect service worker' if they confuse the personal nature of the service with services that support others without direct consumer contact, like a cleaner in a hospital.

Production is divided into three main stages. Primary production involves extracting raw materials from nature, like farming or mining. Secondary production, the correct answer, involves processing these raw materials into finished or semi-finished goods, which is exactly what manufacturing (making products in a factory) and construction (building structures) do. Tertiary production involves providing services, not making physical goods.

Common mistake: Students may mistakenly choose primary production because construction uses raw materials from the earth, but the key is that construction *transforms* these materials, which is the definition of secondary production.

This question tests your knowledge of the factors of production and their specific rewards. The four factors of production are land, labour, capital, and entrepreneurship. Each factor receives a specific payment for its contribution: rent is the reward for land, wages are the reward for labour, interest is the reward for capital, and profit is the reward for the entrepreneur. Option C correctly lists these factors in the same order as their rewards mentioned in the question.

Common mistake: Students often get confused and mix up the order, for example, incorrectly thinking that rent is the reward for capital instead of land, as suggested in option A.

Depreciation is the decrease in the value of an asset over time due to use, wear, and tear. Capital refers to man-made goods like machinery, vehicles, and equipment used in production. These items wear out and lose their value as they are used, which is what we call depreciation. The other factors, like land, usually increase in value (appreciate), while labour and entrepreneurship are human efforts, not physical assets that depreciate.

Common mistake: Students might mistakenly choose 'land' because they think its resources can be used up, but in economics, land is considered a fixed asset that typically appreciates in value, not depreciates.

Division of labour is the process of breaking down a large production task into smaller, simpler tasks for different workers. When a worker repeatedly performs the same small task, they become an expert and highly efficient at it. This expertise in a specific area is known as specialization, which is the main goal and ultimate result of dividing labour.

Common mistake: Students may confuse the process with the outcome and choose 'repetition', but specialization is the ultimate skill that results from the repetition of tasks.

This question tests your knowledge of the types of production. Manufacturing is a type of production that involves converting raw materials into finished goods. In this case, the worker is processing raw rice (paddy) into a finished product (edible rice), which is a manufacturing activity.

Common mistake: Students often mistakenly choose 'extractive activity' because they confuse the processing of rice with the initial farming or harvesting of rice from the land.

A retailer is the trader who sells goods directly to the final consumer. Because they have this direct relationship, they are responsible for providing after-sales services like installation, repairs, and handling complaints to keep their customers happy. This service helps to build customer loyalty and encourages them to buy again.

Common mistake: Students might mistakenly choose 'wholesaler' because they also provide services, but a wholesaler's services are typically for retailers, not the final consumer who receives after-sales support.

Self-service is a retail method where customers are free to move around the store, pick up, examine, and select products from the shelves without the assistance of a shop attendant. This system, common in supermarkets and department stores, gives consumers direct and free access to a wide variety of goods. After making their selections, customers then take the items to a cashier for payment.

Common mistake: Students might mistakenly choose 'vending machine' because it also allows for purchase without an attendant, but it offers a very limited selection and is a specific machine, not a general store layout trend.

Wholesaling is a key part of the chain of distribution where a business buys goods in large quantities, or bulk, directly from the manufacturer. The wholesaler then 'breaks bulk' by selling these goods in smaller quantities to retailers, who in turn sell to the final consumers. The question describes this exact process, making 'wholesaling' the correct answer.

Common mistake: Students might mistakenly choose 'retailing' because it also involves selling goods, but retailers sell in very small units directly to the final consumer, not to other businesses like retailers.

The Balance of Trade measures the difference between the monetary value of a country's exports and its imports over a period. It is the primary account used to show a country's trading position with the rest of the world. While the Balance of Payments is a broader record, the Balance of Trade is the specific component that focuses on the comparison of goods (visible) and services (invisible) traded.

Common mistake: Students often mistakenly choose 'balance of payment' because it is a broader term that includes all international economic transactions, but 'balance of trade' is the more specific term for comparing exports and imports.

An open indent is an order placed by an importer that does not specify the manufacturer from whom the goods should be bought. This gives the agent a 'freehand' or freedom to use their discretion to purchase the goods from any source they consider best. In contrast, a closed indent would restrict the purchase to a specific, named manufacturer.

Common mistake: Students often confuse an open indent with a closed indent, which is the opposite as it restricts the purchase to a specific, named manufacturer.

Entrepot trade is a type of foreign trade where goods are imported into a country, not for its own use, but for the purpose of re-exporting them to another country. The process involves the movement and importation of goods between various countries without being consumed in the intermediary country. Therefore, it is a special form of 'importing goods among countries' where the final destination is another foreign nation.

Common mistake: Students might mistakenly choose option D because it mentions re-exporting, but the entire process is a form of trade between countries that is initiated by importation.

A dock warrant is a document of title issued by a port authority or warehouse keeper. It serves as proof that goods have been received and are being stored in the dock's warehouse. The holder of the dock warrant has the legal right to take possession of the goods or transfer their ownership to another party.

Common mistake: Students often mistakenly choose 'bill of lading' because it is a well-known shipping document, but it is issued by the shipping company for the transportation of goods, not by the port authority for storing them at the dock.

An invoice is a commercial document sent by a seller to a buyer, detailing the goods that have been sold. It lists the items, quantities, and agreed-upon prices for the products or services the seller has provided to the buyer. This document serves as a formal bill and a record of the goods the purchaser is receiving.

Common mistake: Students may mistakenly choose 'an indent' because it also lists required goods, but an indent is an order placed by a buyer, whereas an invoice is the bill sent by the seller confirming the goods supplied.

Dumping is an international trade practice where a country or company exports a product at a price that is lower in the foreign market than in its own domestic market, often even below the cost of production. The main goal is to gain a competitive advantage and capture market share in the foreign country. The question's description of selling goods in foreign countries below their marginal cost is the exact definition of dumping.

Common mistake: Students may mistakenly choose 'devaluation' because it also relates to foreign trade and pricing, but devaluation refers to the official lowering of a country's currency value, not the act of selling a specific product below its cost.

Advertising is the process of making a product known to the public through media like TV, radio, or social media. By telling more people about the product and its benefits, it persuades them to buy it. This action directly increases demand and creates a larger market for the product, making it a key aid to trade.

Common mistake: Students often mistakenly choose 'marketing' because it is a broad concept that includes creating a market, but advertising is the specific activity or process used to achieve this.

Television is a very effective advertising medium because it uses both moving pictures (sight) and sound. This combination appeals to more of our senses, which is called sensory stimulation. This makes the advertisement more engaging, persuasive, and memorable for the audience compared to media like radio (only sound) or newspapers (only sight).

Common mistake: Students might mistakenly choose option D because television does have wide network coverage, but this is not its most unique advantage compared to the powerful sensory impact of combining sight and sound.

Registered mail is a postal service that provides the sender with proof of mailing and a delivery record. It offers extra security because the item is tracked, and the recipient must sign to confirm they have received it. This signature ensures the item gets to the specific person it was addressed to, making it the best mode for this purpose.

Common mistake: Students often confuse 'express mail' with 'registered mail', but express mail prioritizes speed of delivery, not the security and proof of receipt that registered mail guarantees.

This question is about a specific type of marine insurance. Hull insurance provides coverage for the ship itself, which includes its body (the hull), machinery, and equipment. Therefore, a businessman taking this policy aims to protect his investment in the vessel against damage or loss.

Common mistake: Students often confuse hull insurance with cargo insurance; they might wrongly choose option A, as cargo insurance is the policy that covers losses or damages to the goods being transported, not the ship itself.

A broker is an agent whose primary function is to act as an intermediary, connecting a buyer and a seller (their principal) to facilitate a transaction. They negotiate on behalf of the principal but do not take ownership or possession of the goods themselves. This role perfectly matches the description of an agent who brings a customer into business contact with his principal.

Common mistake: Students often mistakenly choose 'factor' because a factor also sells goods for a principal, but they forget that a factor takes physical possession of the goods while a broker does not.

A tourism master plan is a detailed, long-term strategy for developing a country's tourism sector. Without this comprehensive plan, efforts to improve tourism in Nigeria are often uncoordinated and ineffective, leading to slow growth. This plan is crucial because it outlines how to manage resources, develop infrastructure, and market tourist attractions properly, so its absence is a major hindrance.

Common mistake: Students might mistakenly choose 'inadequate tourist centres' because it is a visible problem, but this is often a result of the bigger issue which is the lack of a proper plan to develop and maintain them.

A public warehouse is a storage facility that is available to the general public, including importers, exporters, and other businesses, for storing their goods upon payment of rent. These warehouses are typically owned and managed by the government or public authorities to provide storage services to everyone. Therefore, a warehouse owned and controlled by the government for general use is correctly identified as a public warehouse.

Common mistake: Students often mistakenly choose 'state warehouse' because 'state' sounds like 'government', but a state warehouse is specifically for goods seized by customs, not for general public storage.

A partnership is a business owned by individuals and is not legally separate from them. This means it lacks 'corporate existence' or separate legal personality, unlike a limited liability company which is treated as a separate 'person' in law. Therefore, the partners are personally responsible for the business's actions and debts.

Common mistake: Students often mistakenly choose 'limited liability' because they confuse a general partnership with a limited liability company, which does offer this protection to its owners.
