JAMB Commerce 2021 Past Questions & Answers

The principle of span of control in business management refers to the number of subordinates that a manager can effectively supervise. Option A correctly defines this by stating that the number of employees reporting to one superior should be kept to a workable maximum. This ensures efficient supervision and avoids overburdening the manager or neglecting subordinates.

Common mistake: Students might choose option B, confusing span of control with the principle of unity of command, which states that an employee should report to only one superior.

A sole trader, also known as a sole proprietor, is the single owner of a business. Because they are the only person in charge, they do not need to consult with partners or a board of directors to make choices. This allows them to make decisions very quickly, which is a major advantage in business. This speed and freedom to act is a key benefit of this form of business.

Common mistake: Students might mistakenly choose option D, 'plough all the profits,' because they confuse it with the advantage of keeping all the profits for oneself.

Corporate mergers involve combining two or more companies, which often leads to a larger operational scale. This increased size allows the new entity to achieve economies of scale, meaning it can produce goods or services at a lower average cost per unit due to factors like bulk purchasing, shared resources, and more efficient production processes. Enhancing economies of scale is a primary driver for many mergers.

Common mistake: Students might choose 'facilitate profit maximization' (D) because it is the ultimate goal of any business. However, enhancing economies of scale (C) is a specific and direct method through which mergers contribute to achieving that profit maximization, making it a more precise objective of the merger itself.

The question describes the 'pre-emptive right,' which is a crucial aspect of how companies raise capital by issuing new shares. This right allows existing shareholders to purchase new stock issues before they are offered to the public, ensuring they can maintain their percentage of ownership. It directly relates to the methods and rights involved in financing a business through equity.

Common mistake: Students might choose 'shareholders right' (D) because it sounds generally correct, but 'pre-emptive right' (A) is the specific term for this particular right concerning new share issues, making it the most accurate answer.

Production is the process of creating goods and services to satisfy human wants, which is also known as creating utility. Form utility is the value added to a product by changing its physical form or shape to make it more useful. For example, turning raw wood into a chair or cocoa beans into a bar of chocolate is the creation of form utility, as the raw materials have been converted into a more desirable finished product.

Common mistake: Students sometimes confuse form utility with place utility, but place utility is about moving goods to a convenient location, not changing the actual physical nature of the raw materials.

Commodity money refers to using physical items with intrinsic value, like cowries, salt, or cattle, as a medium of exchange. This form of money was used in ancient times but has gone out of use because it is difficult to carry, divide, and store. The other options, such as paper money and bank money, are forms of modern money that are still widely used today.

Common mistake: Students might get confused and think of old paper notes that are no longer legal tender, but paper money as a general category is still very much in use.

The question describes the core function of marketing, which is to identify and satisfy customer needs. While 'conceptual marketing' isn't a standard term, in this context, it refers to the fundamental idea or concept behind all marketing efforts. The essence of marketing is understanding and fulfilling customer desires.

Common mistake: Students might pick 'micro-marketing' or 'macro-marketing' if they focus on the scale rather than the fundamental purpose of marketing.

Aids to trade are activities that facilitate the smooth exchange of goods and services. Transport (III) helps move goods, Insurance (V) protects against risks, Banking and finance (VI) provides financial services, and Communication (VIII) enables information flow, all of which are essential for trade. Retail, export, import, and wholesale are types of trade, not aids that facilitate it.

Common mistake: Students often confuse types of trade (like retail, wholesale, export, import) with the services that aid trade, leading them to incorrectly include these in their selection.

The communication process involves a sender encoding a message and transmitting it through a channel. The ultimate destination of this transmitted message is the receiver, who decodes and interprets it. Therefore, the message is sent to the receiver to complete the communication loop.

Common mistake: Students might mistakenly choose 'D. sender' or 'A. encoder' because they are involved in the process, but the message is transmitted *from* the sender/encoder, not *to* them.

Bills of exchange and promissory notes are classic instruments of credit. A bill of exchange is a written order to pay a sum of money, often used in international trade, while a promissory note is a written promise to pay a specific sum to another party. Both documents formalize credit arrangements, allowing for deferred payment in the purchase and sale of goods, making them crucial terms and documents in trade.

Common mistake: Students might mistakenly choose options like 'payment vouchers and statement of account' because they are also financial documents, but they are records of transactions or payments, not instruments that formally extend or secure credit like bills of exchange or promissory notes.

In an organization's structure, communication that flows from a higher level to a lower level is called downward communication. A superior, such as a manager or boss, is at a higher level, while a subordinate, or staff member, is at a lower level. Therefore, when a superior gives instructions, feedback, or information to a subordinate, it is an example of downward communication.

Common mistake: Students may mistakenly choose 'upward communication' by confusing the direction of information flow, which is the opposite and moves from a subordinate to a superior.

Net worth, also known as owner's equity, represents the value of a business to its owners. It is calculated by subtracting the total liabilities (what the business owes) from the total assets (what the business owns). Therefore, the excess of assets over liabilities is the net worth of the business.

Common mistake: Students often mistakenly choose 'working capital', but this refers to the funds available for day-to-day operations (Current Assets - Current Liabilities), not the overall value of the business.

The question asks for the 'total sum of financing short term projects'. From the provided balance sheet, the correct answer is ₦200,000, which represents the Share Capital. Share capital is the money invested by the owners (shareholders) into the business. Although it is a long-term source of finance, it contributes to the overall pool of funds available to the company, which can be used to finance various business activities, including short-term projects or working capital needs.

Common mistake: Students might incorrectly choose ₦30,000 (Current liabilities) because current liabilities are explicitly short-term sources of finance, directly matching the 'short term projects' phrase.

Capital employed represents the total long-term funds invested in a business. In this context, it is calculated as the sum of Share Capital and Reserves, which are the owner's equity. Therefore, ₦200,000 (Share Capital) + ₦100,000 (Reserves) equals ₦300,000.

Common mistake: Students often mistakenly include long-term liabilities in the calculation of capital employed, which would lead to ₦340,000 (Option A).

GSM (Global System for Mobile Communications) is a technology for mobile phones. Its most distinctive advantage is mobility, which means users can communicate while moving from one location to another. This allows for flexible and on-the-go communication, which is vital for modern business and personal interactions. It differentiates mobile communication from traditional fixed-line telephones.

Common mistake: Students might incorrectly choose 'coverage' because a wide network coverage is important for mobile phones, but 'mobility' is the core feature that defines and distinguishes mobile communication.

An insurance premium is the price paid for an insurance policy. To calculate the premium for fire insurance, the insurance company assesses the risk of a fire occurring. The type of materials used to build the property (e.g., wood vs. concrete) and its structure are the main factors that determine this risk, so they are the major determinants of the premium.

Common mistake: Students might mistakenly choose option D, but the anticipated extent of damage is more related to the total value to be insured, not the primary factor for calculating the premium rate itself.

The question describes an activity where raw materials are obtained directly from natural sources like land and sea. This process is known as extraction, which is a fundamental type of primary production. Understanding different types of production, including primary, secondary, and tertiary, is key to comprehending commerce.

Common mistake: Students might choose 'agriculture' or 'farming' because they are also primary activities, but 'extraction' is a broader term that includes mining, fishing, and forestry, not just cultivation.

A 'bull' is an investor who believes that the price of a security, such as shares, will increase. They buy these securities with the expectation of selling them at a higher price in the near future to make a profit, which aligns with buying new issues for resale at a higher price.

Common mistake: Students often confuse 'bull' with 'bear', who expects prices to fall, or 'stag', who specifically applies for new issues to sell quickly for profit, which is a more specific type of bullish activity.

The cache is a special, very fast memory that helps a computer's processor work quicker by storing frequently used data. Among the given options, it is the only one that functions as a primary memory component, holding data for immediate processing. Modern communication in commerce relies heavily on computers, making knowledge of their basic components relevant.

Common mistake: Students might mistakenly choose 'console' because it is a physical part of a computer system, but a console is an input/output device (like a screen and keyboard), not a memory component.

The question is about how telephone services are transmitted internationally, which directly relates to the infrastructure and methods of communication. Communication satellites play a vital role in relaying signals across vast distances, enabling telephone calls between different countries. Effective communication is a fundamental aid to trade, facilitating business transactions and coordination globally.

Common mistake: Students might mistakenly choose 'internet services' because the internet is a popular modern communication tool, but communication satellites are the primary technology that facilitates the long-distance transmission of traditional telephone signals across borders.

Registered mail is the best option because it provides a secure way of sending important items. It offers proof of posting and requires the recipient's signature upon delivery, ensuring the item reaches the named address and providing a record of its journey. This method gives the highest assurance of delivery compared to the other options.

Common mistake: Students might confuse 'recorded delivery' with 'registered mail', but registered mail generally offers a higher level of security and tracking, especially for valuable items, making it more effective at ensuring delivery.

An agency relationship is a legal agreement where one person, called the principal, authorises another person, called the agent, to act on their behalf. This contract legally binds the principal to the actions of the agent when dealing with others. Therefore, the two essential parties that must be involved in creating the agency contract are the principal and the agent.

Common mistake: Students might mistakenly choose 'a principal and a third party' because the agent's main job is to connect the principal with a third party, but the actual agency contract is only between the principal and the agent.

Inbound tourism refers to visitors entering a country. When residents of a country travel to other countries, they are considered 'inbound' tourists by the foreign nations they visit. This means they are entering those other countries as visitors, contributing to their tourism sector.

Common mistake: Students often confuse inbound tourism with domestic tourism (residents traveling within their own country) or outbound tourism (residents leaving their country), leading to incorrect selections.

A consortium is an association of two or more companies formed to undertake a project that is too large or complex for any single member to handle alone. They pool resources and expertise for a specific, often temporary, venture. This perfectly matches the scenario described in the question.

Common mistake: Students might confuse 'consortium' with 'merger' or 'amalgamation' because all involve companies coming together, but mergers and amalgamations result in a permanent combination, while a consortium is usually for a specific project.

A trade association is an organization founded and funded by businesses that operate in a specific industry. Its main objective is to protect and promote the common interests of its members, which includes safeguarding them against unfair practices, exploitation, or victimization from external forces like government policies or larger competitors. They act as a collective voice to ensure fair treatment and a level playing field for all members.

Common mistake: Students might choose option C, 'boost the trade of its members,' because trade associations do promote their industry, but their fundamental role is often more about collective protection and advocacy rather than directly increasing individual sales for each member.
