Diminishing returns set in at point T in the production function. In a production function, adding more units of input (such as labor or capital) typically leads to an increase in output at a certain rate. However, as the amount of input increases beyond a certain point, the rate of output increase begins to decline. This is known as the law of diminishing returns. In the diagram, points R and S represent the increasing phase of the production function where output increases at an increasing rate as more input is added. However, at point T, the rate of increase in output begins to slow down, indicating that the law of diminishing returns has set in. Beyond point T, adding more input will result in smaller increases in output, and may even cause a decrease in output if the input becomes too excessive, as shown by point V. Therefore, point T is where diminishing returns set in, indicating the optimal level of input for maximum output.

The reward for land as a factor of production is rent. Rent is the payment made by a tenant or user of land to the owner of the land in exchange for the right to use the land. Land, as a factor of production, refers to the natural resources such as water, air, forests, minerals, and other resources that are used in the production process. Unlike labor and capital, land is considered to have a fixed supply, which means that its availability is limited. Therefore, the price of land is determined by the demand for it, which is influenced by factors such as location, natural resources, and economic activity. In summary, the reward for land is rent, which is the payment made by a tenant or user of land to the owner of the land in exchange for the right to use the land.

The business organization that is allowed to raise capital by sales of shares to more than twenty people is a Public limited liability company (PLC). A Public limited liability company is a type of business organization that is owned by shareholders who own shares of the company. These shares can be bought and sold by the general public, allowing the company to raise capital by selling shares to more than twenty people. In contrast, a Private limited liability company (Ltd) is a type of business organization that is owned by a small group of shareholders who are often family members or close friends. Private limited liability companies are not allowed to sell shares to the general public and are limited to selling shares to a maximum of 20 people. Partnerships and Sole proprietorships are not allowed to issue shares at all, as they are not considered separate legal entities from their owners. Instead, they raise capital by borrowing money from banks, investors or using their own funds.

An upward movement along the same supply curve results in an increase in quantity supplied. This means that as the price of the good increases, suppliers are willing and able to produce and sell more of the good. This is because suppliers are motivated by profit, and as the price of the good goes up, they can earn more profit per unit sold. As a result, they will be willing to produce and sell more units of the good. It is important to note that the supply curve itself does not shift as a result of an upward movement along the curve, only the quantity supplied changes.

Average revenue is obtained by dividing the total revenue by the number of units sold. Thus we have;

660/6 = 110

The coefficient of the price elasticity of supply is positive. This means that as the price of a good or service increases, the quantity of it that is supplied will increase as well. Conversely, if the price decreases, the quantity supplied will decrease. The degree to which the quantity supplied responds to changes in price is what the coefficient of the price elasticity of supply measures. A perfectly elastic supply has an elasticity of infinity, meaning that even a small change in price will result in a large change in the quantity supplied. On the other hand, a perfectly inelastic supply has an elasticity of zero, meaning that the quantity supplied does not change in response to price changes.

The correct answer is a mixed economy. A mixed economy is an economic system that combines elements of both the public (government) and private sectors. In a mixed economy, the government and private businesses work together to create economic growth and promote social welfare. In a mixed economy, the government is responsible for providing essential services such as healthcare, education, and infrastructure. The private sector, on the other hand, is responsible for creating goods and services that meet the demands of the market. This type of economy allows for the benefits of both capitalism (private enterprise) and socialism (public enterprise) to coexist. It allows the government to regulate and control certain aspects of the economy, while still allowing the private sector to operate and innovate freely. Many modern economies around the world are considered mixed economies, including the United States, Canada, and the United Kingdom.

Capitalism or free market economy may be defined as the type of economic system in which the means of production are owned and controlled by private individuals that is; it is characterized by private ownership of the means of production. In this case, the private individuals play a greater role than the government in taking decisions on what to produce, how to produce, for whom to produce and the distribution of what has been produced.

Taxes and government expenditures are instruments of fiscal policy. Fiscal policy refers to the government's use of its spending and taxation powers to influence the economy. By adjusting the level of taxes and government spending, the government can influence the level of economic activity and control inflation. For example, if the government wants to stimulate economic growth, it may lower taxes and increase government spending. This increases consumer spending and investment, which can boost economic activity. On the other hand, if the government wants to slow down inflation, it may raise taxes and decrease government spending, which can reduce consumer spending and slow down economic growth. In summary, fiscal policy is a crucial tool used by governments to manage their economies and maintain economic stability.

The formation of cartels or monopolies in order to obtain better bargaining or deals from other countries is characteristic of countries producing the same or identical goods. When multiple countries produce the same or very similar goods, they may face competition from each other in the global marketplace. This competition can lead to lower prices and lower profits for all the countries involved. To avoid this, these countries may form a cartel or monopoly by agreeing to work together to limit production or fix prices. By doing so, they can increase their bargaining power and negotiate better deals with other countries or buyers. For example, the Organization of the Petroleum Exporting Countries (OPEC) is a cartel made up of oil-producing countries that work together to regulate the supply and price of oil in the global market. By working together, they can maintain higher prices for their oil and negotiate better deals with buyers. Overall, the formation of cartels or monopolies can be a way for countries producing similar goods to gain more control over the market and secure better economic outcomes for themselves.

The reduction in the value of a country's currency in relation to the value of the currencies of other nations is known as "Devaluation". When a country's currency is devalued, it means that the value of its currency has decreased compared to the currencies of other countries. This can happen for a number of reasons, including a decrease in the demand for the country's goods and services, a decrease in the country's economic growth, or a decrease in the country's foreign reserves. A devaluation makes a country's exports cheaper and more competitive on the global market, which can help boost the country's economy. However, it can also lead to higher prices for imported goods, which can negatively impact the country's consumers. In simple terms, devaluation is when a country's currency becomes less valuable compared to other currencies.

The Economic Commission for Africa (ECA) was set up by the United Nations (UN) in 1958. The ECA is one of the UN's five regional commissions and it was established to promote economic and social development in Africa. The ECA's primary objective is to provide research and policy analysis, as well as technical assistance, to African governments, with the goal of supporting their efforts to achieve sustainable and inclusive economic growth. The ECA also works to promote regional integration and cooperation among African countries, as well as to foster partnerships with other regions of the world. Therefore, the correct answer is the UNO.

In the long run, all production factors are variable. This means that in the long run, a firm can adjust all of its inputs, including labor, capital, and resources, to produce the level of output it desires. Unlike the short run, where some production factors are fixed and cannot be changed, the long run allows firms to make changes to all of their inputs, such as investing in new technology or equipment, hiring or firing employees, and even moving to a new location. For example, in the short run, a bakery may only be able to increase its production by hiring more workers or working longer hours, as its oven and baking equipment are fixed. But in the long run, the bakery could invest in new, larger equipment to increase its production capacity, as well as relocate to a larger facility or even open new stores. Therefore, in the long run, all production factors can be adjusted, making them variable, while in the short run, some factors are fixed, making them less adaptable to changes in production levels.

The basic economic problems of society refer to the fundamental challenges that arise from the limited availability of resources and the unlimited wants and needs of individuals and society as a whole. The three main economic problems are scarcity, choice, and opportunity cost. Scarcity refers to the limited availability of resources, such as land, labor, and capital, relative to the unlimited wants and needs of individuals and society. This means that choices must be made about what to produce, how to produce it, and for whom it should be produced. The second economic problem is choice. Because resources are scarce, individuals and societies must make choices about what goods and services to produce and consume. This requires answering questions like "what to produce," "how much to produce," "how to produce it," and "for whom to produce it." These choices have important consequences for the allocation of resources and the distribution of income and wealth. The third economic problem is opportunity cost. This refers to the cost of choosing one option over another, as measured by the value of the best alternative foregone. In other words, every time we make a choice, we give up the opportunity to do something else with those resources. This means that the cost of any choice is not only the direct cost of producing or consuming a good, but also the opportunity cost of not using those resources in some other way. In summary, the basic economic problems of society include scarcity, choice, and opportunity cost. These problems arise from the limited availability of resources relative to the unlimited wants and needs of individuals and society, and require making choices about what to produce, how to produce it, and for whom it should be produced.

The full meaning of NAPEP is National Poverty Eradication Programme. It is a government-led initiative aimed at reducing poverty and improving the standard of living for citizens in a given country. The program typically focuses on providing financial and other forms of support to those living in poverty, with the goal of helping them to become self-sufficient and better able to meet their own needs. The specific activities and approaches of NAPEP can vary from country to country, but the overarching goal is always to help people escape the cycle of poverty and build better lives for themselves and their families.

Total budget = N100,000,000

  Portion of pie chart covered in degree = 360

  Expenditure on manufacturing = x/N100,000,000 × 3600 = 360

  3600x = 360 × N100,000,000

  x = 360×N100,000,000/3600

  x=N10,000,000

  Therefore, the budget allocated to Manufacturing is N10,000,000

  Total budget = N100,000,000

  Portion of pie chart covered in degree = 720

  Expenditure on Agriculture = x/N100,000,000 × 3600 = 720

  3600x = 720 × N100,000,000

  x = 720 × N100,000,000/3600

  x = N20,000,000

  Therefore, the budget allocated to Agriculture is N20,000,000

  Ratio of expenditure on Manufacturing to Agriculture;

  Ratio = 10,000,000:20,000,000

  =1:2

The two major types of international trade are bilateral trade and multilateral trade. Bilateral trade refers to the exchange of goods and services between two countries. It involves the negotiation and agreement of terms and conditions between two parties, and it usually results in a trade surplus or deficit for each country. On the other hand, multilateral trade involves the exchange of goods and services among three or more countries. This type of trade is governed by international trade agreements, such as the World Trade Organization, and aims to promote free trade and economic cooperation among member countries. In summary, bilateral trade involves trade between two countries, while multilateral trade involves trade among three or more countries and is governed by international trade agreements.

The invisible item in the list is "Banking services". In economics, visible items are tangible goods that can be physically seen and touched, while invisible items are intangible services that cannot be physically seen or touched. Petroleum services, processed rice, and processed milk are all visible items because they are tangible goods that can be seen, touched, and measured. On the other hand, banking services are intangible and cannot be physically seen or touched. Examples of banking services include providing loans, managing savings accounts, facilitating transactions, and offering financial advice. Therefore, banking services are considered an invisible item because they are intangible and cannot be physically seen or touched.

The factor of production that has the highest degree of mobility is labor. Labor refers to the human effort used in the production of goods and services. It includes both physical and mental work, such as the work done by factory workers, managers, doctors, and teachers. Unlike other factors of production, such as land and capital, labor is not fixed and can move from one job or industry to another. Labor mobility is the ease with which workers can move between different jobs or locations. It is influenced by factors such as education, skills, training, and the availability of job opportunities. For example, a person with a degree in computer science can easily move from one technology company to another, and a nurse can work in a hospital or a clinic. The mobility of labor is important for the efficient functioning of the economy because it allows workers to move to industries and locations where their skills are in demand, which increases their productivity and wages. It also helps businesses to find the talent they need to grow and innovate, and it enables regions to adapt to changing economic conditions. Therefore, labor mobility is an important aspect of economic growth and development.

Mortgage banks give loans to investors on a long-term basis to build houses. When people want to buy a home, they may not have enough money to pay for it all at once. In this case, they can apply for a mortgage loan from a bank. A mortgage is a loan that is used to buy a property and is usually paid back over a period of several years. Mortgage banks specialize in giving out loans for the purpose of purchasing property, such as homes or other buildings. The loan is typically secured by the property being purchased, which means that if the borrower cannot repay the loan, the bank can take possession of the property to recoup its losses. Investors who want to build houses can also get mortgage loans from banks. In this case, the loan is used to finance the construction of the property, and the property serves as collateral for the loan. Overall, the primary purpose of mortgage banks is to give long-term loans to investors who want to buy or build houses. By providing this service, mortgage banks help to stimulate the housing market and make it easier for people to achieve their dreams of homeownership.

The form of utility that refers to the enhancement of a commodity's usefulness by moving it from a place where it has little utility to another area where its utility is higher is called "place utility." For example, a bottle of water may have low utility in a store shelf where there is an abundance of water, but it would have a higher utility in a desert where water is scarce. By moving the water bottle from the store shelf to the desert, the place utility of the water bottle is increased. On the other hand, marginal utility refers to the additional satisfaction or benefit that a person derives from consuming an extra unit of a good or service, while form utility refers to the value added to a commodity by transforming it into a more useful form, such as processing raw materials into finished products. Total utility, on the other hand, refers to the overall level of satisfaction or benefit that a person derives from consuming a particular quantity of a good or service.

The economic term used to refer to human wants, desires, or needs is "Ends". In economics, ends refer to the goals or objectives that individuals or society aims to achieve. These are the things that people want or need, such as food, shelter, clothing, entertainment, or education. Ends are considered to be unlimited because there are always new wants or needs that arise as people's tastes and preferences change, as well as advances in technology and innovation. However, the resources to satisfy these ends are limited, which creates a problem of scarcity. To achieve these ends, individuals must use alternative means, or resources, such as labor, capital, or natural resources. Therefore, the correct option is "Ends".
