When the price of a product decreases, consumers are generally willing to buy more of it. As a result, the quantity demanded increases. However, since each unit is sold at a lower price, the decline in price outweighs the increase in quantity, leading to a decrease in total revenue (total revenue = price x quantity). This is why a downward sloping demand curve indicates that the total revenue declines as the price is lowered.

The balance of payments is a record of all financial transactions made between consumers, businesses, and the government in one country with others. It includes trade in goods and services, investments, and money transfers. To improve a country's balance of payments, particularly the trade balance, countries may implement certain policies.

Anti-dumping policies are used to prevent foreign companies from selling goods at a price lower than their market value to gain an unfair advantage. By implementing anti-dumping policies, a country can protect its domestic industries from unfair competition, which can help improve the balance of payments by reducing imports or encouraging domestic consumption.

Granting subsidies to export producers can help improve the balance of payments by making domestic products cheaper and more competitive in international markets. By lowering production costs, subsidies can help increase exports, leading to an improvement in the balance of payments.

Increasing import duties is another way to improve the balance of payments. By imposing higher taxes on imported goods, a country can discourage imports and encourage consumers to purchase domestically produced goods. This can improve the trade balance by reducing the outflow of money used to purchase foreign products.

On the other hand, decreasing taxation on personal income doesn't directly affect the balance of payments. Reducing personal income tax may increase disposable income for consumers, which could lead to more consumption. However, this increased consumption might not necessarily focus on domestic goods, and could instead lead to higher imports. Therefore, among the options listed, decreasing taxation on personal income is the one least likely to directly improve a country's balance of payments.

Nigeria's agricultural policies are fundamentally designed to enhance and support the agricultural sector for the overall benefit of its economy and citizens. Let's analyze the objectives given:

• Provision of food: This is a core objective of agricultural policies. Ensuring food security by making food consistently available and affordable is a primary aim to combat hunger and malnutrition.
• Provision of agricultural raw materials to industrial sectors: Agricultural policies seek to supply raw materials such as cotton, cocoa, and rubber to industries, supporting the economy's industrial sectors.
• Creation of rural employment: Job creation in rural areas is a crucial focus. By developing agriculture, more employment opportunities can be generated, reducing rural poverty and discouraging rural-urban migration.
• Increasing prices of agricultural Inputs: Contrary to the other objectives, raising the prices of agricultural inputs is generally not an aim of agricultural policies. Instead, policies often aim to reduce costs or provide subsidies for inputs to support farmers, make farming more profitable, and enhance overall productivity.

Therefore, the statement that does not align with the typical objectives of agricultural policies in Nigeria is the increasing prices of agricultural Inputs. Instead, policies are often geared towards making inputs more affordable to support agricultural growth.

Wholesalers play a significant role in the distribution of goods and services for several key reasons:

1. Bulk Purchasing and Distribution: Wholesalers buy large quantities of goods from producers and sell them in smaller lots to retailers, which allows them to benefit from economies of scale. This bulk buying helps keep costs low for retailers and ultimately consumers.

2. Bridging the Gap: By acting as an intermediary between producers and retailers, wholesalers play a crucial role in the supply chain. They enable manufacturers to focus on production while handling the complexities of distribution and logistics.

3. Financial Support: Wholesalers sometimes provide credit to retailers, allowing them to purchase goods and pay later. They also assist producers by buying inventory upfront, providing necessary funds for the producers to continue their business.

4. Information Exchange: Wholesalers gather market trends and feedback from retailers and share this information with producers. This helps producers adjust their products to meet consumer demands more effectively.

5. Inventory Management: Wholesalers manage storage and inventory, reducing the burden on manufacturers and retailers. They ensure a steady supply of products, minimizing the risk of stockouts or overproduction.

In summary, wholesalers are essential in the distribution network because they facilitate product flow, support financial operations, manage distribution logistics, and collect market intelligence.

A persistent fall in the general price level is known as deflation.

To understand this better, let's break it down:

• General Price Level: This refers to the average of current prices across the entire spectrum of goods and services produced in the economy. It is like taking a snapshot of what prices look like overall in the economy.


• Deflation: This is the term used when the general price level is consistently decreasing over time. In simpler terms, it means that prices of goods and services are falling, making them cheaper for consumers. This might sound beneficial to consumers initially, but prolonged deflation can lead to reduced consumer spending, as people may delay purchases in anticipation of even lower prices. This can subsequently slow down economic growth and potentially lead to an economic recession.

Hence, when we say "persistent fall in the general price level," we are accurately describing deflation.

In the given equation Q = a - bp + e, we need to understand the roles of the variables Q and P.

In any equation where we are trying to establish a relationship between two variables, one of the variables is usually controlled or changed deliberately, while the other one is observed as it changes in response. In such equations:

• The **independent variable** is the one that you control or change to see how it affects another variable. It is like the **cause** or **input**.
• The **dependent variable** is the one that changes as a result of the changes in the independent variable. It is like the **effect** or **output**.

In the equation Q = a - bp + e, **Q** is the outcome or result that we observe, and it depends on the value of **P**. Thus, **Q is the dependent variable** because it changes depending on the values of **P**. Conversely, **P** is the one that we can change or manipulate in the context of this equation, so **P is the independent variable**.

Therefore, the correct description for **Q** and **P** is that Q is the **dependent** variable, and P is the **independent** variable.

An exceptional demand curve occurs when demand does not follow the typical downward slope from left to right. Instead, the demand curve may slope upward. Let’s consider some scenarios that could lead to this unusual situation.

Increase in Price of Raw Materials: This typically affects the supply side rather than the demand side. When prices of raw materials increase, production costs go up, possibly reducing supply, but not necessarily impacting demand directly. Therefore, this is not usually a reason for an exceptional demand curve.

Change in Taste of Consumer: If consumers suddenly prefer a particular product, they may be willing to buy more even if the price rises. This shift in consumer preferences can lead to an upward-sloping demand curve, reflecting increased demand despite higher prices.

Increase in the Size of the Population: More people can lead to higher overall demand, but each individual’s demand curve typically still slopes downward due to the law of diminishing marginal utility. Therefore, population increase alone generally does not cause an exceptional demand curve.

Expectation of Future Price Increase: When consumers expect prices to rise in the future, they may choose to buy more now to avoid paying higher prices later. This situation can lead to an upward-sloping demand curve as current demand increases with rising prices, due to future price expectations.

In summary, an exceptional demand curve is usually caused by changes in consumer tastes or expectations of future price increases, making current demand behave in an unexpected way compared to the usual downward slope.

In the long-run, a firm must shut down if its average revenue is less than its average variable cost. This is because the firm is unable to cover even its variable costs, which are the costs it incurs when it produces any output at all. Let me explain further:

• A firm's goal is to maximize profit. To do this, a firm must ensure that it can at least cover its variable costs in the short-term. Variable costs include things like labor and raw materials, which are necessary for production.
• If the firm cannot cover the variable costs, it indicates that producing a unit of output adds more cost than revenue. Therefore, producing any more output will increase losses, making it better for the firm to shut down operations.
• In the long-run, all costs become variable, and if the firm's revenue doesn't cover these costs, the firm will not be able to survive.

To put it simply, if average revenue is less than average variable cost, the firm can't sustain itself in the long-run, and shutting down is a rational decision.

To determine how many students are in SSS, we first need to figure out how many students are in JSS. According to the problem, 60% of the school's population is in JSS.

Here's a simple breakdown:

• The total population of the school is 600.
• 60% of 600 is calculated by multiplying 600 by 0.60. Mathematically, this is:
• 600 x 0.60 = 360. So, there are 360 students in JSS.

Since the whole school has 600 students, and 360 of those are in JSS, we can find out how many are in SSS by subtracting the JSS students from the total number of students:

600 - 360 = 240

Hence, there are 240 students in SSS.

In Nigeria, marketing boards were established to regulate and promote agricultural products. Their primary functions include activities like grading farm produce to ensure quality standards and marketing farm produce by finding markets where these products can be sold. They are also responsible for fixing prices for farm produce to stabilize farmers' incomes and protect them from market fluctuations.

However, one activity that marketing boards do not typically perform is the importation of farm produce. Marketing boards are mainly concerned with the domestic production and distribution of local agricultural products, whereas the importation would fall under international trade domains and different regulatory agencies. Thus, the importation of farm produce is not a usual function of marketing boards in Nigeria.

The act of cultivating land and rearing of animals for man's use is known as agriculture.

Agriculture is an activity that involves growing crops and raising animals to provide food, fiber, medicinal plants, and other products used to sustain and enhance human life. It is a vital practice that has been developed over thousands of years, allowing civilizations to flourish by ensuring a stable supply of food and resources. This practice not only involves the cultivation of the land for crops but also includes various other activities such as animal husbandry, which is the breeding and care of farm animals.

Let me explain a bit about the other terms you mentioned:

• Forestry refers to the management and conservation of forests and woodlands. It involves the planting, maintaining, and caring for trees and forests. While it might also involve the cultivation of certain types of land, its primary focus is on trees rather than a wide range of crops or livestock.
• Mono culture is a term used to describe the cultivation of a single crop in a given area, year after year. This is a method within agriculture but does not encompass the full scope of agriculture, which includes diversity in crop and animal production.
• Horticulture is a branch of agriculture that focuses on the cultivation of plants, fruits, vegetables, flowers, and ornamental plants. It deals mainly with garden crops rather than large-scale agricultural crops and usually doesn't focus on animal rearing.

Thus, the most comprehensive term that covers both the cultivation of land and rearing of animals is agriculture.

In developing countries, the largest component of national income typically consists of wages and salaries. This means that the income earned by individuals from their employment or labor work forms a significant part of the national income. Several reasons contribute to this:

• Labor-Intensive Economy: Developing countries often have labor-intensive sectors such as agriculture, manufacturing, and services, which employ a large number of people. These sectors need a substantial workforce, leading to the major share of national income coming from wages and salaries.
• Lower Levels of Capital: Capital refers to tools, equipment, and machinery used in production. Developing countries may have lower levels of capital investment, focusing more on labor to boost production, which again increases the share of wages and salaries in national income.
• Demographics: Developing countries often have younger populations with a high dependency on labor for earning income. This means most people derive their livelihood through working jobs rather than owning businesses or properties, leading to wages and salaries dominating national income.

In contrast, components like rent and profit tend to form a smaller component of national income in developing economies. While these components are important, they are usually not as predominant as wages and salaries due to the lesser commercialization and capital-intensive industries compared to developed countries.

Economics problems arise in all societies primarily because resources are not in adequate supply. This is known as the fundamental economic problem of scarcity. In every society, there are limited resources but unlimited wants and needs. These resources include things like land, labor, and capital, which are necessary for producing goods and services. Since we do not have enough of these resources to satisfy everyone's desires, we face choices about how to allocate them efficiently.

The issue of scarcity leads to other economic problems such as deciding what to produce, how to produce it, and for whom it should be produced. These decisions are made by assessing opportunity costs and considering how to make the best possible use of the limited resources available.

While factors such as lack of proper planning or mismanagement by leaders can exacerbate economic problems, they are not the root cause. The core issue remains the limited availability of resources, compelling societies to prioritize and decide how best to meet the needs of their population.

The formula (N + 1)/2 is used to determine the median position in a dataset that is arranged in ascending or descending order. Understanding how to find the median is important because the median is a measure of central tendency that represents the middle value of a dataset. Here's a clear explanation of this concept:

When you have a set of numbers, the median is the number that falls in the middle when the numbers are arranged in either increasing or decreasing order. To find this middle value, you can use the formula (N + 1)/2, where N represents the total number of observations in the dataset.

For example, let's say you have a dataset with an odd number of observations: 3, 5, 7. Here, N is 3, so you apply the formula:

Median position = (3 + 1)/2 = 2

This calculation indicates that the second number in this ordered list is the median, which is 5.

If you have an even number of observations, such as 2, 4, 6, 8, you would calculate the median position as follows:

Median position = (4 + 1)/2 = 2.5

In this case, because 2.5 isn't an integer, the median is the average of the second and third numbers, which are 4 and 6. Therefore, the median is (4 + 6)/2 = 5.

In summary, the formula (N + 1)/2 is used to identify the position of the median in a list of numbers that are ordered, allowing us to understand where the middle point of the data lies.

The **economic problem** arises due to the fundamental concept of **scarcity**. In simple terms, scarcity means that the resources available to us are **limited**, while our desires and needs are **unlimited**. This situation forces us to make decisions about how best to allocate our resources efficiently.

Because of scarcity, every choice we make involves a **trade-off**. For instance, if you choose to spend your time studying economics instead of mathematics, you sacrifice the benefits you would have gained from studying mathematics. The concept associated with this scenario is called **opportunity cost**, which is essentially the value of the next best alternative forgone when making a decision.

Furthermore, scarcity leads to the necessity of **choice**. Individuals, businesses, and governments must decide what to produce, how to produce, and for whom to produce. These choices are influenced by the limited resources and the alternatives available.

While **money cost** is often considered in decisions, it is not the root cause of the economic problem. It is a **monetary representation of value** and is used as a tool to navigate scarcity and opportunity cost.

In essence, the **economic problem exists** because we have to make choices about how to use our scarce resources most effectively, and every choice involves an opportunity cost. This continual need to prioritize options is at the very heart of economics.

Competitive demand refers to a situation where two or more goods are seen as substitutes for each other. When the pric of one commodity increases, consumers tend to shift their demand towards the substitute commodity, resulting in a decrease in the demand for the original commodity.
For example, if the price of coffee increases significantly, some consumers may choose to switch to tea as a substitute. A: a result, the demand for coffee decreases while the demand for tea increases.

When measuring national income using the **Income Approach**, the focus is on summing up all the **incomes earned** by individuals and businesses in an economy for providing goods and services. This typically includes wages, profits, rents, and interest received. Let's examine each option:

• **Profit earned by NITEL plc**: This is included because it is part of the profits earned by businesses.
• **Profit earned by Nigerian Bottling Company plc**: This is included for the same reason as above; it is business profit, which is a component of national income.
• **Income earned by a bricklayer**: This is included because it's a wage or salary, which is a fundamental part of national income.
• **Allowance given to an aged mother by a civil servant**: This is **NOT included** in measuring national income through the income approach. The reason is that these are private transfer payments or personal transfers, not payments made for labor, production of goods, or capital services.

In economics, the demand for factors of production is best described as being derived. What this means is that the demand for these factors, like labor, land, and capital, is not for their own sake but because of the demand for the goods and services they can produce.

To put it simply, businesses need these factors of production to create products. If there is a high demand for a particular product, there will naturally be a higher demand for the factors needed to produce that product. Conversely, if there is little to no demand for a product, then the demand for the factors required to produce it will also decrease.

For example, if there is a high demand for cars, a car manufacturing company will need more metal, labor, and machinery, which are the factors of production, to make more cars. Thus, the demand for these factors is based on, or derived from, the demand for the cars themselves.

The equilibrium price in economics is a fundamental concept where the market operates most efficiently. To understand it fully, consider the following explanation:

When demand equates supply, it indicates the price at which the quantity of goods consumers are willing to buy (demand) is exactly equal to the quantity of goods producers are willing to sell (supply). This is the point where the market reaches equilibrium. At this price, there is no excess supply or demand, meaning that resources are being used most effectively, and there is no pressure on the price to change.

In contrast:

• If the price equals demand only, this would imply a scenario that doesn't exist in standard economic terms because equilibrium involves both supply and demand.
• When demand is less than supply, it suggests a surplus in the market, leading to downward pressure on price as sellers attempt to clear excess stock.
• If demand is greater than supply, it leads to a shortage, resulting in upward pressure on prices as consumers compete to buy the limited available goods.

Thus, at equilibrium price, demand equates supply, ensuring the market operates smoothly without surplus or shortage.

When an economy is experiencing a balance of payments surplus, it means that the country is exporting more goods, services, and capital than it is importing. Essentially, there is more money flowing into the country than out of it. In such situations, one of the most viable actions to take is to increase its foreign reserves.

Here's why increasing foreign reserves is often the best option:

• Stability and Security: Increasing foreign reserves can help the country maintain better economic stability and provide a financial cushion. These reserves can be used in times of economic distress, for example, to stabilize the country's currency or to cover the balance of payments deficit if one arises in the future.
• Credibility and Investor Confidence: A healthy level of foreign reserves signals to international investors and creditors that the country is financially stable, which can lead to greater investor confidence and potentially more foreign investment.
• Currency Support: With a surplus, increasing reserves can support the country's currency value in global financial markets. This helps maintain favorable exchange rates and can be used strategically by the central bank to control currency appreciation.
• Flexibility in Monetary Policy: Higher foreign reserves give the central bank more flexibility in its monetary interventions. They can control inflation and manage interest rates more effectively.

Promoting imports, while it can help reduce the surplus by encouraging money to flow out of the country, may not always be the best course of action and depends on the country's economic goals and import needs. Borrowing from abroad is generally not necessary when the country has a surplus. Devaluing the currency is certainly not favorable in the context of a surplus as it can create inflationary pressures and reduce purchasing power internationally.

The level of consumption generally refers to the amount of goods and services that households are willing and able to purchase. This can be influenced by several factors:

Level of Income: The more income people earn, the more they can spend on goods and services, which directly affects consumption levels. With higher income, households typically increase their consumption.

The Rate of Taxes Paid: Taxes directly impact disposable income, which is the income available after tax deductions. Higher taxes reduce disposable income and may lead to lower consumption, while lower taxes increase disposable income and can potentially boost consumption.

Savings: When households allocate a portion of their income to savings, this reduces the immediate level of consumption. Therefore, high levels of savings can indicate lower levels of consumption.

The Political Climate: Although the political climate can affect the economy in various ways, it is generally not a direct and immediate determinant of consumption levels. The political climate can influence factors like economic stability and government policies, but it is not a direct factor in determining how much households consume.

Based on these explanations, the factor that determines the level of consumption the least is the political climate, because its effects are indirect and less immediate compared to the direct effects of income, taxes, and savings on consumption.

The expenditure approach is a common method used to calculate the national income, specifically the Gross Domestic Product (GDP) of a country. This approach sums up all expenditures or spending in the economy.

The correct formula for the expenditure approach is: Y = C + I + G + (X - M), where:

• C stands for Consumption: This is the total value of all goods and services consumed by households within the economy. It includes expenditures on items such as food, clothing, housing, and other personal expenses.
• I stands for Investment: This includes spending on capital goods that will be used to produce other goods and services in the future, such as machinery, buildings, and inventory.
• G stands for Government Spending: This is the total expenditure by the government on goods and services, including public sector salaries, defense, education, and infrastructure projects.
• (X - M) stands for Net Exports: This is calculated as total exports (X) minus total imports (M). Exports are goods and services sold to other countries, while imports are those bought from other countries. By subtracting imports from exports, we determine the net trade effect on the economy.

Putting it all together, this formula helps to calculate the total economic activity within a country by summing up consumption, investment, government spending, and net exports, giving a comprehensive picture of the national income.

In the context of production, the Total Product (TP) refers to the total quantity of output produced by a firm. The Marginal Product (MP) is the additional output obtained by employing one more unit of a specific input, while keeping all other inputs constant.

When the Total Product starts to fall, it indicates that each additional unit of input is contributing less and less to the total output, to the extent that the output is actually decreasing. This means that any added input is no longer producing additional output but instead reducing it. Therefore, the Marginal Product in this situation is actually negative.

Here is why:

• Consider the scenario where adding extra workers or resources does not increase output, and might even disrupt production.
• At this point, the contribution of added input becomes detrimental, causing a decline in the total output.
• Thus, the Marginal Product turns negative, because the next unit of input is not just unproductive, it makes the overall production lower than before.

The terms MPC and MPS are concepts from economics that describe how households make spending and saving decisions out of their income. Let's break these down for a better understanding:

• MPC (Marginal Propensity to Consume): This represents the portion of additional income that a household is likely to spend on consumption rather than saving. For example, if someone's income increases by $100 and they spend $80 of that increase, their MPC would be 0.8 (80/100).
• MPS (Marginal Propensity to Save): Conversely, this is the portion of additional income that a household is likely to save rather than spend. Continuing the previous example, if the household saves $20 out of the $100 increase in income, their MPS would be 0.2 (20/100).

The sum of MPC and MPS must equal 1 because the additional income can only be spent or saved, meaning there aren’t any other alternatives for allocating this extra income. Therefore, mathematically, we express it as:

MPC + MPS = 1

In a closed economy model, the whole of any extra income is divided into consumption and saving, thereby making 1 the correct answer. So, whenever income changes, whatever portion is not spent (MPC) is saved (MPS), summing it up to one.

In a capitalist economic system, several features define its characteristics. To understand which of the given options is NOT a feature of capitalism, let's examine each one:

Free Enterprise: This is a fundamental aspect of capitalism. It refers to the freedom of businesses to operate competitively for profit with minimal government intervention. Under free enterprise, individuals and businesses have the right to sell goods and services, decide on investments, and set prices.

Private Ownership of Property: Another core feature of capitalism is the ownership of property by individuals or corporations rather than by the government. In this system, individuals have the right to own assets, resources, and production facilities. They can use, rent, or sell property as they see fit.

Competition: Competition is a driving force in capitalism. It encourages businesses to improve their products and services, enhance efficiency, lower prices, and innovate. Healthy competition is believed to lead to better choices and quality for consumers.

Detailed Economic Planning: This is NOT a feature of capitalism. Detailed economic planning is more characteristic of socialist or centrally planned economies where government agencies set production targets, control resources, and address distribution centrally. Capitalism relies more on market forces and price mechanisms to guide economic decisions rather than detailed and centralized planning.

Therefore, detailed economic planning is the correct answer as it is NOT a feature of capitalism.

When a joint-stock company goes bankrupt, the owners or shareholders of the company only lose the capital they invested in that company. This is because joint-stock companies have a feature known as **limited liability**.

Limited liability means that shareholders are only responsible for losses up to the amount of money they invested in purchasing shares of the company. Therefore, in a bankruptcy situation, they **lose only the capital invested**, and their personal or private assets (like cars, houses, or bank accounts) are protected and not at risk. They are not liable beyond their shareholding, hence they do not lose their private properties or any future dividends they were expecting.

This feature of limited liability is very important as it encourages people to invest in joint-stock companies without the fear of losing their personal wealth.

The satisfaction derived from the consumption of a commodity is referred to as utility. To explain this concept further, let's break it down:

Utility is an economic term that describes the pleasure, happiness, or satisfaction a consumer gets from consuming goods and services.

Here’s why it is the correct term:

• When you purchase or consume something, like a snack or a service, the positive feelings or fulfillment you get is called its utility.
• The concept of utility is used in economics to understand consumer behavior, such as how much of a product consumers might be willing to buy at different prices, based on the satisfaction they expect to gain.
• Increasing or maximizing one's utility often drives decisions, as individuals usually aim to derive the most satisfaction from their choices.

In summary, whenever we talk about the satisfaction from using or consuming goods, we are discussing the concept of utility.

Deflationary policies refer to economic strategies aimed at reducing inflation and stabilizing prices. However, these policies can also have several disadvantages that can negatively impact an economy.

One major disadvantage of deflationary policies is unemployment in the country. These policies often involve reducing the money supply or increasing interest rates. When the money supply is reduced, businesses may have less access to credit and may experience decreased consumer spending. This can lead to lower production and, consequently, job cuts, increasing unemployment.

Deflationary policies may also lead to a decrease in investments, as higher interest rates make borrowing more expensive. Companies might delay or reduce their investment plans, creating a ripple effect that dampens economic growth and job creation. As more people are unemployed, there is less consumer spending, which can further exacerbate economic stagnation.

On the other hand, while these policies could potentially lead to an improved standard of living in the long run by stabilizing prices, the immediate term is often marked by challenges. These policies are designed to control costs; however, the path to reaching that stability can be quite turbulent.

In summary, the main disadvantage of deflationary policies is their potential to increase unemployment and dampen economic growth, despite their goal of stabilizing the economy.

When a government has its revenue receipts less than the expenditure in a fiscal year, the country is experiencing a deficit budget. Here's a simple explanation:

Revenue receipts are the funds government receives, mainly from taxes and other sources like fees, interests, etc.

Expenditure refers to the total amount of money the government spends on various needs like infrastructure, education, defense, welfare programs, and salaries.

If the money received (revenue receipts) is less than the money spent (expenditure), it indicates that the government is spending more than it is earning. This excess expenditure generates a gap which is known as a deficit.

To address this deficit, governments might need to borrow money or reduce spending to balance their finances in the future. Hence, when expenditure surpasses revenue, it results in a deficit budget.

Factors of production are the inputs used to produce goods and services in an economy. The main factors of production include land, labor, capital, and entrepreneurship. Each of these factors receives a specific reward or return:

• Land: The reward for using land as a factor of production is rent. Rent is the payment made for the use of land or real estate resources.
• Labor: The reward for labor is typically in the form of wages or salaries. It represents the compensation paid to workers for their productive efforts.
• Capital: The reward for capital, which includes machinery, tools, or financial capital used in production, is interest. It is the return on investment for using capital resources.
• Entrepreneurship: The reward for entrepreneurship, which involves the risk-taking and organization of other factors of production, is profit. Profit is the financial gain realized by entrepreneurs for their ventures.

The term subsidy is generally not a reward for factors of production. A subsidy is a financial assistance granted by the government to individuals or businesses to support activities, promote economic growth, or reduce the cost of certain goods and services. It is not directly linked to any of the classical factors of production.

In conclusion, while profit, rent, and interest are returns directly associated with factors of production, a subsidy is not. It serves a different purpose in economic policy.

The middle value of an array of figures arranged in descending order is referred to as the median.

To understand this concept, imagine you have a collection of numbers, and you want to find the one that sits right in the middle when all numbers are lined up from the largest to the smallest (or even from smallest to largest, as the median remains the same).

• If there is an odd number of values in your dataset, the median is the number that is directly in the middle. For example, in the dataset {9, 7, 5}, the median is 7, as it is the middle number.


• If there is an even number of values, the median is calculated by taking the average of the two middle numbers. For instance, in the dataset {10, 8, 6, 4}, the two middle numbers are 8 and 6, and their average is (8 + 6) / 2 = 7. Therefore, 7 is the median.

The median is very useful as a measure of central tendency because it is not affected by extremely large or small values in the dataset, which could skew other measurements like the mean. Thus, it provides a better representation of a typical value within the dataset, especially when dealing with outliers.

The stock exchange market primarily deals with the sales of second-hand securities. In this context, "second-hand securities" refer to financial instruments such as stocks and bonds that have already been issued by a company and are currently being traded among investors. When a company first issues stocks or bonds, it is done in the primary market. Once these securities are purchased and then resold by investors, they are traded in the secondary market, commonly known as the stock exchange.

Here's a simple rundown of how it works:

1. **Initial Offering:** A company looking to raise capital might issue stocks or bonds to investors. This takes place in the primary market through an Initial Public Offering (IPO) or similar mechanisms.

2. **Secondary Trading:** Once issued, these securities can be bought and sold on the stock exchange. Investors trade these securities based on supply and demand, trying to make a profit by buying low and selling high.

Therefore, the stock exchange acts as a platform where buyers and sellers meet to trade these second-hand securities. This buying and selling provide the liquidity required for the market to function efficiently and helps in price discovery of the securities based on market demand.

The International Monetary Fund (IMF) is an international organization that primarily focuses on ensuring the stability of the international monetary system. Here are some of its core functions:

• Providing financial aid to members experiencing balance of payment difficulties: The IMF provides financial assistance to countries facing balance of payment problems. This helps stabilize their economies and restore growth.
• Promoting international monetary cooperation: The IMF encourages international collaboration in monetary policies to sustain financial stability and growth across nations.
• Exchange rate stabilization: The IMF works with countries to help stabilize their exchange rates by providing policy advice and financial assistance, aiming to avoid competitive devaluations and maintain global economic equilibrium.

The statement that is NOT a function of the IMF is "assisting member countries in printing and issuing their currency." The IMF does not assist countries in printing or issuing their currency. This activity is typically managed by each country's own central bank or monetary authority. Thus, this function does not fall under the responsibilities of the IMF.

The Production Possibility Curve (PPC), also known as the Production Possibility Frontier, is a graphical representation that illustrates the concept of scarcity, trade-offs, and opportunity cost. It shows the different combinations of two goods or services that an economy can produce given its finite resources and technology.

The factors typically highlighted by a PPC are as follows:

• Scarcity of resources: This is emphasized as it limits the production possibilities for an economy, thereby creating the necessity to allocate resources efficiently.
• Unemployment of labour: Although the PPC assumes full employment of resources, any point inside the curve indicates that resources, including labor, are not being fully employed.
• Inefficiency in the use of resources: This is indicated by points inside the PPC curve, which shows that resources are not being used optimally.

However, a point that is not emphasized within a PPC is:

• Economic development: The PPC does not directly illustrate concepts such as economic growth or development. While economic growth can shift the PPC outward, the curve itself does not explain the aspects of long-term growth, improvement in living standards, or the underlying factors of economic development like technology advancements, better education, and institutional changes.

Thus, the concept that is not highlighted in a PPC is economic development.

In a free market economy, multiple producers are allowed to enter the market and compete with each other. This competition creates incentives for producers to become more efficient in order to gain a competitive advantage. When producers compete, they strive to offer better quality products, lower prices, and improved customer service. To achieve these goals, they need to find ways to reduce costs, increase productivity, and innovate. The pressure of competition encourages producers to constantly improve their efficiency to attract customers and maximize profits

The concept we are discussing here is the Price Elasticity of Demand (PED). It measures how much the quantity demanded of a commodity changes with a change in its price. The formula for calculating the price elasticity of demand is:

PED = (% Change in Quantity Demanded) / (% Change in Price)

First, we calculate the percentage change in quantity demanded:

• Initial quantity demanded = 100 units
• New quantity demanded = 80 units
• Change in quantity demanded = New quantity demanded - Initial quantity demanded = 80 - 100 = -20 units

Percentage change in quantity demanded:

= (Change in quantity demanded / Initial quantity demanded) × 100

= (-20 / 100) × 100 = -20%

Next, calculate the percentage change in price:

• Initial price = N8.00
• New price = N10.00
• Change in price = New price - Initial price = N10.00 - N8.00 = N2.00

Percentage change in price:

= (Change in price / Initial price) × 100

= (2 / 8) × 100 = 25%

Now, we can substitute these values into the formula for PED:

PED = (% Change in Quantity Demanded) / (% Change in Price)

= (-20%) / (25%)

= -0.8

The price elasticity of demand is -0.8. The negative sign indicates that there is an inverse relationship between price and quantity demanded, which is normal for most goods. This value rounded to the nearest value provided in your options is 0.8. This implies it is inelastic demand, meaning the quantity demanded is not very responsive to price changes.

A price floor is a **minimum price** set by the government for a particular good or service. It is designed to ensure that the price is not too low, often supporting producers by maintaining their income at a viable level.

For a price floor to be effective, it is usually fixed **above the equilibrium price.** Here's why:

• **Equilibrium Price** is where the supply of a product equals the demand for that product. It is the point at which the market is said to be in balance.
• When a price floor is set **above the equilibrium**, it means that the price consumers are willing to pay is less than the price producers are willing to accept. This leads to a decrease in quantity demanded by consumers since the price is too high for them.
• Thus, producers end up with **more goods available than what consumers are buying**, creating a **surplus**. This surplus occurs because the set price is prohibiting the market from reaching its natural balance or equilibrium.

Therefore, a price floor is usually fixed **above the equilibrium and causes surpluses.** This allows it to serve its purpose of protecting producer revenues while potentially benefiting certain industry stakeholders.

In any economy, the problem of "how to produce" is essentially about deciding the best way to combine resources to produce goods and services. This challenge can be effectively addressed by adopting the least cost method of production.

Here’s why:

• Objective: The key objective for any economy is to produce goods and services efficiently, using the least amount of resources possible, while maximizing output. This ensures that the resources, which are often limited, are utilized in the most productive way.


• Resource Allocation: By focusing on the least cost method, producers aim to determine the proportion of capital (like machines, tools, and buildings) and labor (human effort) that should be used to minimize costs and maximize profits. This can involve a mix of both capital and labor-intensive methods depending on which combination minimizes production costs.
• Flexibility: The least cost method is iterative and allows for adjustments based on changes in resource availability, technological advancements, and shifts in market conditions, ensuring the production process remains cost-effective and competitive.


• Consumer Benefits: When producers focus on minimizing costs, they can offer products at lower prices, making goods and services more affordable for consumers, which can increase demand and boost the overall economy.

In summary, while other methods and managerial skills are important, addressing how to produce in the most efficient and effective way often boils down to using the least cost method of production, thereby ensuring optimal resource use and economic stability.
