Question 1 of 20
JAMB · Commerce · 2005

The existence of limited resources to satisfy unlimited human wants leads to the concept of:

A. Efficiency
B. Scarcity
C. Elasticity
D. Equilibrium
Explanation

One might think of Efficiency or Equilibrium when evaluating economic systems, but those relate to resource allocation or market balance rather than the core restriction itself. When limited resources meet unlimited wants, the fundamental condition created is scarcity, requiring choices. Common mistake: Confusing the outcome of resource limits with the tools used to manage them.

Question 2 of 20
JAMB · Commerce · 2005

Which of the following is a tertiary industry?

A. Mining
B. Farming
C. Banking
D. Fishing
Explanation

Options like Mining and Farming might look like valid economic activities, but they belong to primary industries. Tertiary industries provide services, like banking, which distinguishes them from primary or secondary sectors. Common mistake: Failing to categorize business sectors correctly into primary, secondary, and tertiary.

Question 3 of 20
JAMB · Commerce · 2005

A retailer buys goods worth ₦200,000 and receives a trade discount of 15%. If a cash discount of 5% is offered for payment within 10 days, calculate the amount paid with both discounts.

A. ₦161,500
B. ₦170,000
C. ₦180,000
D. ₦190,000
Explanation

Students might miscalculate by forgetting to apply the cash discount or adding percentages instead of multiplying. To find the correct amount paid, first compute the trade discount of 15% on ₦200,000, which gives ₦30,000 and reduces the price to ₦170,000. Next, apply the 5% cash discount to ₦170,000 to get ₦8,500, resulting in an final amount paid of ₦161,500. Common mistake: Applying both discounts directly to the original price simultaneously rather than sequentially.

Question 4 of 20
JAMB · Commerce · 2005

A business formed by a voluntary association of individuals with common economic, social, and cultural needs is a:

A. Sole proprietorship
B. Cooperative society
C. Public corporation
D. Partnership
Explanation

A test-taker might confuse this with a Partnership or Sole proprietorship, but those are primarily for profit generation by individuals or small groups. A business formed by a voluntary association of individuals with common economic, social, and cultural needs is a cooperative society, which prioritizes mutual welfare. Common mistake: Confusing the mutual social goals of cooperatives with standard profit-seeking partnerships.

5
Question 5 of 20
JAMB · Commerce · 2005

The principle of mutual agency in a partnership implies that:

A. Decisions require unanimous consent
B. Each partner can bind the firm
C. Profits are shared equally
D. New partners need all consent
Explanation

One might mistakenly believe that Decisions require unanimous consent, but partnerships operate under a specific legal framework of delegation. Mutual agency allows each partner to act for the firm, binding all partners to business agreements. Common mistake: Assuming all partnership choices require every single partner to vote.

6
Question 6 of 20
JAMB · Commerce · 2005

The document that outlines the rules and regulations governing the internal management of a company is the:

A. Certificate of Incorporation
B. Prospectus
C. Articles of Association
D. Memorandum of Association
Explanation

Options like Prospectus or Certificate of Incorporation might seem plausible for company setup, but they deal with public shares or official registration status. The document that outlines the rules and regulations governing the internal management of a company is the Articles of Association. Common mistake: Confusing the external formation documents with internal administrative bylaws.

7
Question 7 of 20
JAMB · Commerce · 2005

The process of holding goods in anticipation of future demand is known as:

A. Transportation
B. Warehousing
C. Retailing
D. Wholesaling
Explanation

Students could mix this up with Retailing or Wholesaling, but those involve buying and selling rather than the physical holding function. Warehousing stores goods for future demand, bridging the time gap between production and consumption. Common mistake: Confusing the physical storage function of trade with the distribution channels.

Question 8 of 20
JAMB · Commerce · 2005

A small retail business that focuses on selling a specific type of product is a:

A. Department store
B. Supermarket
C. Specialty store
D. General store
Explanation

You might choose a Department store or Supermarket, but those carry a wide variety of merchandise rather than a narrow focus. A small retail business that focuses on selling a specific type of product is a specialty store. Common mistake: Confusing broad multi-department stores with niche retail outlets.

Question 9 of 20
JAMB · Commerce · 2005

Which of the following is a benefit of specialization in commerce?

A. Reduced interdependence
B. Increased self-sufficiency
C. Simpler exchange processes
D. Higher production and efficiency
Explanation

One might think specialization leads to self-sufficiency, but it actually increases interdependence among producers and workers. Specialization boosts production and efficiency via focused skills. Common mistake: Believing that narrowing down a task makes a person or business more independent.

Question 10 of 20
JAMB · Commerce · 2005

Which of the following is a desirable characteristic of money?

A. Instability of value
B. Durability
C. Lack of uniformity
D. Difficulty in portability

Choices like Instability of value or Difficulty in portability are undesirable traits, which makes them incorrect. Durability ensures money withstands physical wear and tear over time. Common mistake: Selecting characteristics that make currency less reliable or functional.

11
Question 11 of 20
JAMB · Commerce · 2005

A retailer sells an item for ₦500, earning a profit of 25% on the cost price. Calculate the cost price.

A. ₦400
B. ₦450
C. ₦375
D. ₦425
Explanation

A student might incorrectly calculate 25% of the selling price instead of the cost price, leading to the wrong figure. Given that the selling price equals 1.25 times the cost price (since selling price is cost plus 25% profit), dividing ₦500 by 1.25 gives a cost price of ₦400. Common mistake: Calculating the profit percentage using the selling price instead of the cost price base.

12

JAMB · Commerce · 2005

Which of the following is a form of above-the-line promotion?

A. Sales contests
B. Free samples
C. Point-of-sale displays
D. Television commercials
Explanation

Options like Point-of-sale displays or Free samples are forms of below-the-line promotion because they involve direct or targeted marketing. Above-the-line promotion uses mass media, like television commercials. Common mistake: Confusing direct promotional incentives with mass media advertising.

JAMB · Commerce · 2005

The primary aim of branding is to:

A. Simplify distribution
B. Increase physical attributes
C. Differentiate a product

A. Long-term investment decisions
B. Setting strategic direction
C. Coordinating departments
D. Supervising operational staff
Explanation

Students could pick Long-term investment decisions or Setting strategic direction, but those belong to top-level management.

A. Debentures

JAMB · Commerce · 2005

Liabilities represent:

A. Resources owned
B. Profit earned

JAMB · Commerce · 2005

Which of the following is NOT a function of the Nigerian Deposit Insurance Corporation (NDIC)?

A. Assisting distressed banks
B. Issuing currency
C. Insuring deposits
D. Regulating banks

18
Question 18 of 20
JAMB · Commerce · 2005

A company has current assets of ₦250,000, including inventory of ₦80,000, and current liabilities of ₦100,000. Calculate the quick ratio.

A. 1.7:1
B. 2.5:1
C. 0.8:1
D. 1.2:1
Explanation

A student might mistakenly include inventory in the calculation, using current assets directly without subtracting inventory first. Quick assets equal ₦250,000 minus ₦80,000, which gives ₦170,000, and dividing this by current liabilities of ₦100,000 yields a quick ratio of 1.7:1. Common mistake: Forgetting to remove less-liquid inventory from current assets when computing the quick ratio.

19

JAMB · Commerce · 2005

Which of the following is a tool of fiscal policy?

A. Open market operations
B. Adjusting discount rate

JAMB · Commerce · 2005

The principle of absolute advantage in international trade suggests a country should:

A. Import all goods

C. Export all goods
