Question 1 of 20
JAMB · Commerce · 2021

Tolu purchased goods from Yemisi and is to pay custom duties before collection. The goods are likely to be collected from

A. a manufacturer’s warehouse
B. a bonded warehouse
C. an importer’s warehouse
D. a wholesaler’s warehouse
Explanation

A student might incorrectly choose a manufacturer's or wholesaler's warehouse, assuming goods always return to their point of production or general distribution hubs. Because custom duties must be settled before goods are cleared, Tolu will collect them from a bonded warehouse, which specifically stores imported goods pending duty payment. Common mistake: confusing general storage facilities with a bonded warehouse designated for customs-cleared goods.

The three major functional units which the modern computer has are

A. the input, processor, and output units
B. the black box, output, and input units
C. BASIC, COBOL, and output units
D. BASIC, the processor, and PASCAL
Explanation

Learners could mistakenly select options mentioning BASIC or black boxes, confusing programming languages or unrelated concepts with core hardware structures. A modern computer is fundamentally comprised of the input units, processor, and output units, which handle data entry, processing, and display. Common mistake: including programming languages or software terms in computer hardware units.

A. I, II, and III
B. I, II, and V
C. II and V
D. I and II
Explanation

A test-taker might erroneously include foreign exchange reserves or short-term lending, mixing up capital account components with financial reserves or different account types. The capital account specifically tracks flows like foreign investment (I), long-term lending (II), and short-term borrowing (V). Common mistake: including foreign exchange reserves in the capital account.

Question 4 of 20
JAMB · Commerce · 2021

The elimination of faults in a computer program is called

A. console
B. debug
C. dump
D. loop
Explanation

Students might mistakenly select console, dump, or loop, confusing program output displays, memory printouts, or repetitive structures with error correction. The specific process of identifying and fixing errors in a computer program is called debugging. Common mistake: confusing program debugging with running a loop or console command.

Question 5 of 20
JAMB · Commerce · 2021

Aliyu bought 100 shares at the stock market through a stockbroker. He was told the price of each share was N3 cum div. This means that Aliyu

A. is entitled to a cumulative dividend on the shares
B. is entitled to the next dividend accruing from the shares
C. will not be entitled to the next dividend due to the shares
D. still owes N3 on the shares which will be subtracted from the dividends
Explanation

Students might mistakenly lean toward option A or D assuming that cum div implies an ongoing cumulative entitlement or an immediate liability deduction, but the pricing mechanism directly guarantees that the purchaser will receive it upon purchase. Because the share price includes the right to the next dividend, Aliyu is entitled to the next dividend accruing from the shares. Common mistake: Confusing the price inclusion of a forthcoming dividend with owing money or holding a continuous cumulative stock preference.

6
Question 6 of 20
JAMB · Commerce · 2021

The forum for the selling and buying of securities of small and medium companies is called

A. Second Tier Foreign Exchange Market
B. Foreign Exchange Market
C. Securities and Exchange Commission
D. Second Tier Security Market
Explanation

Students might look at options like A or B because they involve exchange markets, but those pertain to foreign currencies rather than corporate equities. The Second Tier Security Market facilitates trading of securities for small and medium-sized companies, aiding their capital access. Common mistake: Mistaking foreign exchange platforms for domestic equity markets designated for smaller firms.

7
Question 7 of 20
JAMB · Commerce · 2021

A wholesale dealer in securities is known as

A. a stockbroker
B. speculator
C. jobber
D. stag
Explanation

Students could erroneously select options like A or D, which describe brokers or speculative market participants rather than wholesale traders. A jobber is a professional dealer who buys and sells securities in bulk, acting as a market maker on the stock exchange. Common mistake: Confusing an intermediary stockbroker with a jobber who trades in bulk on their own account.

8
Question 8 of 20
JAMB · Commerce · 2021

Modern business philosophy emphasizes

A. quality products
B. customer satisfaction
C. sales volume
D. public relations
Explanation

Test-takers might be tempted by options like A or C due to their heavy emphasis on physical goods and output metrics. Modern business philosophy prioritizes customer satisfaction, focusing on meeting customer needs to ensure loyalty and long-term success. Common mistake: Equating high sales volume or premium product quality with the core consumer-centric philosophy of modern enterprises.

Question 9 of 20
JAMB · Commerce · 2021

The main role of advertising is to

A. convince prospective buyers to buy
B. show the actual shape, form, and colour of the products
C. inform people where to obtain goods and services
D. capture the attention of people
Explanation

Candidates might select options like B, C, or D because advertisements do inform and capture attention visually, but those are secondary functions. Advertising primarily aims to persuade prospective buyers to purchase products or services through compelling and targeted messages. Common mistake: Confusing the preliminary steps of drawing attention or showing product features with the ultimate persuasive goal of advertising.

10
Question 10 of 20
JAMB · Commerce · 2021

The concept of limiting the types, sizes, and other characteristics of a product line without sacrificing utility or durability is called

A. simplification
B. standardization
C. specialization
D. satisfying
Explanation

Students may confuse this with standardization or specialization, which deal with uniformity or skill focus rather than trimming variety. Simplification reduces product variety while maintaining utility and durability, streamlining production and inventory management. Common mistake: Confusing product line reduction (simplification) with creating uniform manufacturing norms (standardization).

11
Question 11 of 20
JAMB · Commerce · 2021

The focal point of all marketing efforts is the

A. customer
B. competition
C. product
D. market share
Explanation

Students might choose options like C or D, thinking the physical item or market standing drives the business. The customer is the core of marketing efforts, as satisfying their needs drives effective strategies and business success. Common mistake: Placing the physical product ahead of the consumer as the primary driver of marketing decisions.

12
Question 12 of 20
JAMB · Commerce · 2021

Aligun displays goods on shelves in his supermarket. This is an example of

A. invitation to treat
B. offer to purchase
C. offer to sell
D. invitation to sell
Explanation

Test-takers might incorrectly choose an offer to sell or purchase, assuming the supermarket layout constitutes a binding direct contract. Displaying goods on shelves is an invitation to treat, prompting customers to make an offer to buy, which the seller can accept or reject. Common mistake: Treating a mere display of goods as a legal offer instead of an invitation for customers to make an offer.

13
Question 13 of 20
JAMB · Commerce · 2021

The process of bringing a company under exclusive ownership and control is known as

A. nationalization
B. commercialization
C. indigenization
D. privatization
Explanation

Students could mistakenly select options like commercialization, indigenization, or privatization which involve private transfer or structural reforms rather than absolute state ownership. Nationalization involves the government taking full ownership and control of a company, often to serve public interests. Common mistake: Confusing government takeover (nationalization) with transferring state assets to private hands (privatization).

14
Question 14 of 20
JAMB · Commerce · 2021

Quoting as the agent of P, Q lawfully and reasonably incurs the amount of N50 as expenses. If Q comes to P for payment, this instance of P’s duty is to

A. repay Q
B. indemnify Q
C. maximize Q
D. settle Q
Explanation

Candidates might be misled by options like A or C, which use general terms like repay or maximize rather than the precise legal obligation. P has a duty to indemnify Q, compensating for reasonable expenses incurred while acting as P’s agent, as per agency law. Common mistake: Failing to recognize the legal term of art indemnity when an agent incurs authorized expenses on behalf of a principal.

15
Question 15 of 20
JAMB · Commerce · 2021

In a hire purchase agreement between Argungu Ltd and Maikudi, Argungu Ltd inserted a provision that it can enter Maikudi’s premises at any time and remove the hired vehicle for any breach. This provision is

A. lawful to both
B. unlawful to both
C. beneficial to both
D. detrimental to both
Explanation

Students might think the clause is beneficial or lawful because it protects the hiring company's financial interests in default scenarios. The provision is unlawful as it violates Maikudi’s privacy and property rights, rendering it unenforceable under contract law. Common mistake: Assuming a hire-purchase vendor holds an absolute right to trespass and repossess without proper legal procedures.

16
Question 16 of 20
JAMB · Commerce · 2021

In every simple contract, the price which was paid to purchase a promise is called

A. offer
B. acceptance
C. consideration
D. representation
Explanation

Students could easily confuse this with an offer or acceptance, which are foundational agreement stages rather than the actual price paid. Consideration is the value or price exchanged for a promise in a contract, making it legally binding and enforceable. Common mistake: Confusing the initial agreement components with the legal value given in exchange for a promise.

17
Question 17 of 20
JAMB · Commerce · 2021

One major disadvantage of a cartel is that it

A. maximizes productive efficiency
B. reduces competition
C. maximizes profits from operation
D. eliminates waste
Explanation

Candidates might choose options relating to efficiency or waste elimination, misinterpreting cartel behavior as a form of streamlined production. A cartel reduces competition by colluding to control prices and output, leading to higher prices and inefficiencies for consumers. Common mistake: Believing that monopolistic collusion benefits consumers by eliminating market waste.

18
Question 18 of 20
JAMB · Commerce · 2021

Staff position in an organization borders on

A. authority
B. advice
C. responsibility
D. control
Explanation

Test-takers might mistakenly select authority or control, assuming that organizational staff roles carry direct command power. Staff positions provide advisory and support roles to line managers, lacking direct authority over operational decisions. Common mistake: Confusing the advisory capacity of a staff position with the direct command authority of a line position.

19
Question 19 of 20
JAMB · Commerce · 2021

The line function in a typical manufacturing enterprise is normally performed by the

A. public relations department
B. estate or properties department
C. marketing department
D. security department
Explanation

Students might incorrectly pick the public relations or security departments, viewing them as core operational units. The marketing department performs line functions, directly contributing to core activities like sales and promotion in a manufacturing firm. Common mistake: Failing to distinguish between supporting staff functions and core revenue-generating line departments like marketing.

20

A. Men, machines, and markets
