Question 1 Report
.............is presently used in Nigeria to measure inflation
Answer Details
The measure that is presently used in Nigeria to measure inflation is the Consumer Price Index (CPI). The CPI is a commonly used indicator worldwide to track changes in the cost of living over time.
The Consumer Price Index (CPI) measures the average price changes of a basket of goods and services typically purchased by households in a specific country or region. It reflects the price movements of essential items such as food, housing, transportation, healthcare, education, and many other goods and services that people consume regularly.
The CPI is calculated by collecting price data for various items in the basket and assigning them weights based on their relative importance in household spending. The prices are then compared to a base period, which is usually a specific year. The percentage change in the CPI from the base period indicates the rate of inflation or deflation.
In Nigeria, the CPI is used to monitor and analyze changes in the cost of goods and services, allowing policymakers and economists to assess the impact on consumers' purchasing power and make informed decisions. It helps in determining the effectiveness of government policies, evaluating the performance of the economy, and adjusting wages and prices.
By tracking the CPI, the government can identify if there is an increase in the general level of prices, indicating inflation, or a decrease, indicating deflation. This information helps in formulating monetary and fiscal policies to control inflation rates and maintain price stability.
Overall, the Consumer Price Index (CPI) is the measure currently used in Nigeria to gauge inflation and is crucial in understanding how the cost of living changes over time, impacting the economy and the daily lives of individuals and businesses.
Question 2 Report
The principle that specified that the amount, when and how to pay tax should be made known to tax payer is known as
Answer Details
The principle that specifies that the amount, when, and how to pay tax should be made known to the taxpayer is known as the Principle of Certainty. This principle ensures that taxpayers have a clear understanding of their tax obligations, which includes knowing the amount of tax they owe, the deadline for payment, and the method of payment.
The Principle of Certainty is important because it promotes transparency and accountability in the tax system. By providing clear and specific information to taxpayers, it enables them to accurately calculate and plan for their tax obligations. This helps to avoid confusion or misunderstandings between the taxpayer and the tax authorities.
Furthermore, the Principle of Certainty also ensures fairness and consistency in the tax system. By clearly stating the rules and requirements, it ensures that all taxpayers are treated equally and that there is no ambiguity or room for arbitrary decisions in the tax assessment process.
Overall, the Principle of Certainty provides a solid foundation for the relationship between taxpayers and tax authorities. It establishes clear expectations, promotes compliance, and adds credibility to the tax system.
Question 3 Report
Economists refer to private goods as
Answer Details
Private goods are referred to as rivalrous and excludable by economists. Let me explain what this means in a simple and comprehensive way.
When a good is rivalrous, it means that one person's use or consumption of the good diminishes its availability for others. For example, if you eat an orange, there is now one less orange for someone else to consume. The consumption of the orange by one person reduces the availability of the orange for others.
On the other hand, when a good is excludable, it means that it is possible to prevent someone from using or consuming that good if they do not pay for it. For instance, if you go to a movie theater and buy a ticket, you are allowed entry to watch the movie. However, if you do not buy a ticket, you will be excluded from watching the movie.
Private goods possess both of these characteristics. They are rivalrous because one person's use or consumption of the good reduces its availability for others. For example, if you buy a car, only you can use it at any given time, and someone else cannot simultaneously use it. Private goods are also excludable because it is possible to prevent others from using or consuming the good if they do not pay for it. For instance, if you purchase a book, you have exclusive access to read it unless you choose to share it with someone.
In summary, private goods are referred to as rivalrous and excludable because their consumption diminishes their availability for others, and it is possible to exclude others from using or consuming them if they do not pay for them.
Question 4 Report
Which of the following is an example of expansionary monetary policy by the Central Bank of Nigeria?
Answer Details
An example of expansionary monetary policy by the Central Bank of Nigeria is "buying Treasury securities from commercial banks." Expansionary monetary policy is a type of policy implemented by the central bank to stimulate economic growth and increase the supply of money in the economy. This policy is typically used during times of economic downturn or recession to encourage spending and investment. When the Central Bank of Nigeria buys Treasury securities from commercial banks, it injects money into the economy. This increases the amount of money available in the banking system, making it easier for banks to lend to businesses and individuals. By increasing the money supply, the central bank aims to lower interest rates, which in turn encourages borrowing and spending. Lower interest rates mean that businesses and individuals can access credit more easily, leading to increased investment, consumer spending, and economic growth. This expansionary policy can help support economic activity, boost employment, and stimulate overall economic recovery.
Question 5 Report

- The fiscal policy is implemented by the reduction of taxes and increasing government spending in order to boost demand.
- Policymakers may choose to implement a stabilization policy to close the recessionary gap and increase real GDP.
Question 9 Report
Which of the following is an example of free good?
Answer Details
An example of a free good is water in the ocean.
A free good is a good that is available in unlimited supply and does not require any payment or exchange to obtain it.
In the case of water in the ocean, it is freely available and accessible to anyone. It is not owned by anyone and does not require any payment to access or use it. Therefore, it can be considered a free good.
On the other hand, free education, dinner you did not pay for, and your rented apartment are not examples of free goods.
Free education typically refers to education that is provided without direct payment by the student. While it may be free for the student, someone is still paying for it, such as the government or private institutions.
A dinner that you did not pay for may seem free to you, but someone, such as a friend or a host, is still paying for it. The cost of that dinner is borne by someone else, even if it is not you.
Similarly, a rented apartment is not a free good because it involves a transaction where you pay for the use of the apartment. You enter into a contractual agreement with the landlord and pay rent in exchange for living in the apartment.

Answer Details
The fundamental problem of Economics is Scarcity. Scarcity explains the basic economic problem that the world has limited or scarce resources to meet seemingly unlimited wants, and this reality forces people to make decisions about how to allocate resources in the most efficient way.
Question 12 Report
The rate of output per worker (or group of workers) per unit time is called
Answer Details
The correct answer is labour productivity.
Labour productivity refers to the rate at which output is produced by a worker or a group of workers in a given amount of time. It measures how efficiently and effectively workers are using their skills, time, and resources to produce goods or services.
To understand this concept, let's imagine a scenario where we have two workers producing bicycles. Worker A is able to produce 5 complete bicycles in one hour, while Worker B can only produce 3 complete bicycles in the same amount of time.
In this case, Worker A has a higher labour productivity because they are able to produce more output (bicycles) per unit of time (one hour) compared to Worker B.
Labour productivity is an essential measure for companies and economies because it directly impacts their profitability and competitiveness. Higher labour productivity means that more goods or services can be produced using the same amount of resources or in less time. This leads to lower costs per unit and can result in higher profits or the ability to lower prices for customers.
In summary, labour productivity is a measure of how efficiently workers are producing goods or services and is calculated by dividing the total output by the number of workers or the amount of time it took to produce that output.
Question 13 Report
If demand function for a product is Qd = 30 - 4P, and the price and quantity of products is 4 and 14 respectively. What is the price elasticity of demand for the product?
Answer Details
Q = 14, P = 4
Qd = 30 - 4p
∆q/∆p = - 4
Ed = ΔqΔp×pq
= - 4 x 4/14
= Ed = -1.14
since price elasticity is positive, then Ed = 1.14

An industry is a group of firms producing similar products and under separate administration or management.
Question 15 Report
Which of the following Age group belongs to active Labour force?
Answer Details
The age group that belongs to the active labor force is the **18 - 64 years** category. This age range is generally considered to be the working-age population, as it encompasses individuals who are old enough to work and have not yet reached the age of retirement. People in this age group are typically in their prime working years, where they have the physical ability and the necessary skills and knowledge to actively participate in the labor market. They are often seeking employment, working in various industries or sectors, and contributing to the economic growth and development of their country. It is important to note that the specific age range considered as the working-age population may vary slightly across different countries or regions. However, in most cases, it generally falls within the **18 - 64 years** age bracket. On the other hand, the other age groups mentioned in the options are not typically considered as part of the active labor force: - The **0 - 17 years** age group consists of individuals who are below the legal working age and are typically attending school or dependent on others for their livelihood. - The **15 - 25 years** age group partially overlaps with the working-age population, but it includes individuals who may still be in school or pursuing higher education. While some individuals within this age range may be actively seeking employment or working part-time, they are generally not considered as the core active labor force. - The **65 years and above** age group represents individuals who have reached the retirement age or are eligible for retirement benefits. While some individuals in this age range may continue to work, either out of choice or due to financial circumstances, they are not considered as the primary active labor force. In summary, the **18 - 64 years** age group is the one that belongs to the active labor force, consisting of individuals who are in their prime working years and actively participating in the labor market.
Question 16 Report
Answer Details
Investment multiplier (K) is a function of two factors; The MPS and MPC. If MPC is high, K will also be high but if MPC is low, K will also be low. on the other hand, If MPS is high, K will be low and if MPS is low, K will be high ( since there is an inverse relationship between MPS and K).
Question 17 Report
The marginal propensity to consume is
Answer Details
The marginal propensity to consume (MPC) is a measure of how much of an increase in income is typically spent on consumption. It is represented by the symbol c or ΔC/ΔY. To explain it simply, the MPC tells us the proportion of additional income that is used for consumption rather than saving or other purposes. For example, if the MPC is 0.8, it means that for every additional unit of income, 0.8 units are typically spent on consumption. The MPC can also be understood as the slope of the consumption function. The consumption function is a mathematical relationship between income and consumption. The MPC represents how much consumption changes for a given change in income. In the equation C = C + cYd, the coefficient c represents the MPC. This equation shows that consumption (C) is determined by autonomous consumption (C) plus the product of the MPC (c) and disposable income (Yd). In summary, the MPC is a measure of how much additional income is typically used for consumption. It can be represented as ΔC/ΔY, the slope of the consumption function, or the coefficient c in the consumption equation.
Question 18 Report
Agriculture accounts for about 60% of the
Answer Details
Agriculture accounts for about 60% of the active labour force in West Africa. This is because a large portion of the population in West Africa is engaged in farming and other agricultural activities for their livelihood. The other options are incorrect as agriculture does not account for 60% of the arable land, service sector activities, or the commodity market in West Africa.
Question 19 Report
Economics is often described as a science because it
Answer Details
Economics is often described as a science because it uses scientific methods to explain observed phenomena. Just like other scientific fields, economics relies on gathering data, formulating hypotheses, and conducting experiments to test these hypotheses. However, unlike fields such as physics or chemistry, economics does not rely on laboratory experiments or controlled experiments. Instead, economists analyze real-world data to understand how individuals, businesses, and governments make choices and interact with each other. They use statistical methods to analyze this data and make predictions about how changes in various factors will affect economic outcomes. While it is difficult to accurately predict the behavior of individual human beings, economics aims to make accurate predictions on aggregate behavior, or how groups of people will respond to changes in factors such as prices, taxes, or policies. These predictions are based on the analysis of historical data and the use of economic models, which simplify complex economic interactions. In summary, economics is considered a science because it employs scientific methods to explain observed phenomena, although it does not rely on laboratory experiments or controlled experiments. It uses data analysis, hypothesis testing, and economic models to understand and predict how individuals and groups make economic decisions and interact with each other.
Question 20 Report
From the graph above, the consumer is at equilibrium at point
Answer Details
Based on the graph, the consumer is at equilibrium at point k.
Equilibrium is when the quantity demanded by the consumer is equal to the quantity supplied by the market. At equilibrium, there is no shortage or surplus of the goods or services.
Point k on the graph represents the intersection of the demand curve (D) and the supply curve (S). At this point, the quantity demanded (Qd) and the quantity supplied (Qs) are equal.
If the consumer is at any other point on the graph, either to the left or to the right of point k, there would be either a shortage or a surplus of the goods or services. This would mean that the demand and supply are not in balance and the market is not at equilibrium.
Therefore, point k is the correct answer as it represents the position where the consumer is at equilibrium.
Question 21 Report

Answer Details
The Gross Domestic Product is the total monetary or market value of all the goods and services produced within a country. It is used to measure the rate of growth in an economy.
Question 22 Report
Part-time workers who desire full-time employment are:
Answer Details
Part-time workers who desire full-time employment are classified as underemployed and contribute to the unemployment statistic.
Underemployment refers to a situation where individuals are working fewer hours than they would like or in jobs that do not utilize their skills and qualifications fully. In this case, part-time workers who desire full-time employment are considered underemployed because they are not able to secure the desired amount of work hours.
These underemployed workers contribute to the unemployment statistic because they are actively seeking additional work hours to meet their employment needs. They are considered part of the labor force because they are willing and available to work more hours, but they have not been able to find full-time employment.
It is important to note that not all underemployed workers contribute to the unemployment statistic. Some may choose to work part-time for personal reasons, such as family responsibilities or pursuing education. These individuals, although underemployed, are not actively seeking additional work hours and therefore do not contribute to the unemployment statistic.
However, in the case of individuals who are part-time workers and desire full-time employment, their underemployment status reflects the inadequacy of available job opportunities. They increase the count of unemployed individuals because they are willing and actively searching for additional work.
It is worth mentioning that cyclical unemployment is a different type of unemployment. It occurs when there is a downturn in the economy, causing a decrease in overall demand for goods and services, and subsequently, a decrease in the demand for labor. Cyclical unemployment is not directly related to the part-time workers' desire for full-time employment.
Question 23 Report
40 men were employed in a farm, and they produced an average of 30 tonnes of cassava per person. Calculate the total product.
Answer Details
To calculate the total product of cassava, we need to multiply the average production per person by the number of people.
In this scenario, we know that there were 40 men employed in the farm, and each person produced an average of 30 tonnes of cassava.
So, to find the total product, we need to multiply 40 by 30.
40 x 30 = 1200
Therefore, the total product of cassava is 1,200 tonnes.
Question 24 Report
Money could be defined as
Answer Details
Money can be defined as a medium of exchange that is universally accepted for buying goods and services. It enables people to easily trade with one another, without the need for bartering or trading directly with goods. In simpler terms, money is like a common language that everyone understands and uses to exchange things they want or need.
Money also serves as a settlement of debt because it allows individuals, businesses, and even governments to repay what they owe. When someone borrows money or takes a loan, they can later use money to pay back the lender. Similarly, if someone owes money to another person, they can use money to settle that debt.
Additionally, money is a medium of payment. It is used to complete transactions and make payments for goods and services. Whether you are buying groceries, paying for a movie ticket, or purchasing a new gadget, money is the common method of payment.
To summarize, money is a medium of exchange, settlement of debt, and medium of payment. It simplifies trade, enables the repayment of debts, and facilitates transactions in our daily lives.
Question 25 Report
Calculate the equilibrium level of national income (Y) where Y = C + I + G; C = 100 + 0.75Y; I = 50; G = 200
Answer Details
To calculate the equilibrium level of national income (Y), we start with the equation Y = C + I + G. In this equation, C represents consumption spending, I represents investment spending, and G represents government spending. Now, let's substitute the given values into the equation: C = 100 + 0.75Y I = 50 G = 200 Substituting these values, we get: Y = (100 + 0.75Y) + 50 + 200 To solve for Y, we need to simplify the equation: Y = 100 + 0.75Y + 50 + 200 Combining like terms, we have: Y = 350 + 0.75Y Next, we can solve for Y by isolating it on one side of the equation. To do this, we can subtract 0.75Y from both sides: Y - 0.75Y = 350 Simplifying further, we have: 0.25Y = 350 Finally, we can solve for Y by dividing both sides of the equation by 0.25: Y = 350 / 0.25 Calculating this, we find: Y = 1400 So, the equilibrium level of national income (Y) is 1400.
Question 26 Report
The decision to consume more of one product under normal circumstances will apply
Answer Details
The decision to consume more of one product under normal circumstances will **result in less consumption of another product**. When we have a limited amount of resources, we can only allocate them in certain ways. This is true for both individuals and businesses. If we choose to consume more of one product, it means we are using some of our resources to produce more of that product. As a result, we have less resources available to produce or consume other products. Let's take an example to understand this concept better. Suppose you have $10 to spend on food, and you can either choose to buy more fruits or more vegetables. If you decide to buy more fruits, it means you are allocating more of your budget towards fruits. As a result, you will have less money left to buy vegetables. On the other hand, if you decide to buy more vegetables, it means you are allocating more of your budget towards vegetables, and you will have less money left to buy fruits. Similarly, in a market economy, if consumers decide to buy more of one product (like smartphones), the demand for that product increases. This leads to an increase in production and consumption of smartphones. However, the resources used to produce smartphones are limited. Therefore, the production of other products (like laptops or tablets) may decrease because fewer resources are available to produce them. In conclusion, when the decision is made to consume more of one product, it generally means that less of another product will be consumed. This is because resources are limited and need to be allocated among different options.
Question 27 Report
Government uses all of the following ways to redistribute income, except
Answer Details
The government uses various methods to redistribute income in society. Three of these ways are market intervention, transfer earnings, and taxation. Market intervention involves the government stepping in and regulating certain aspects of the economy to ensure fairness and reduce income inequality. For example, the government may set a minimum wage so that workers are guaranteed a certain level of income. Transfer earnings refer to government programs that provide financial assistance to individuals or families who are in need. These programs include welfare, unemployment benefits, and social security. The goal is to provide support to those who may have lower incomes or are facing financial difficulties. Taxation is another method used by the government to redistribute income. Through taxes, the government collects money from individuals and businesses based on their income or profits. This revenue is then used to fund public services such as healthcare, education, infrastructure, and social programs. However, the answer to the question is that the government does not use limited liability as a way to redistribute income. Limited liability is a legal concept that protects individuals from being personally liable for the debts and liabilities of a company. It is not directly related to income redistribution. In summary, the government redistributes income through market intervention, transfer earnings, and taxation. These methods aim to promote fairness and provide support to those in need. However, limited liability is not a method used for income redistribution.
Question 28 Report
Economic problem occurs when
Answer Details
The economic problem occurs when there is scarcity relative to demand. Scarcity means that resources are limited, while demand refers to people's desires and needs for goods and services. In simple terms, the economic problem arises when there are not enough resources to satisfy everyone's wants and needs. This is because resources, such as land, labor, and capital, are finite, while people's desires are infinite. For example, imagine a small community with a limited amount of food available. If everyone in the community wants to eat, but there is not enough food for everyone, it creates an economic problem. This scarcity can lead to competition, as individuals and businesses try to obtain the limited resources. The economic problem is not caused by raw materials being imported or people being out of work. These factors can contribute to a country's economic challenges, but they are not the direct cause of the economic problem. Similarly, the absence of buyers for goods is a symptom of the economic problem, rather than the cause. If people cannot afford or do not want to buy goods, it indicates a mismatch between supply and demand. However, this does not explain why the economic problem exists in the first place. In summary, the economic problem occurs when there is scarcity relative to demand, meaning there are not enough resources to fulfill everyone's wants and needs. This scarcity leads to competition and the need for individuals and businesses to make choices regarding resource allocation.
Question 29 Report
Which of the following is the resultant effect of a fall in the profit margin of producers in an economy?
Answer Details
A fall in the profit margin of producers in an economy will likely result in an increase in unemployment.
When the profit margin of producers decreases, it means that they are earning less profit from their business activities. As a result, they may struggle to cover their costs, sustain their operations, or expand their businesses. To manage their financial situation, producers may need to cut costs, reduce production, or even close down their business altogether.
Reduced production and business closures lead to a decrease in job opportunities and an increase in unemployment. When businesses are not making enough profit, they may need to lay off workers or reduce their workforce in order to cut costs. This means that fewer people will have jobs, resulting in higher unemployment rates.
Additionally, a fall in profit margins can also deter new businesses from entering the market or existing businesses from expanding. This further limits job creation and can exacerbate the unemployment problem.
In summary, a fall in the profit margin of producers in an economy leads to reduced production, business closures, job cuts, and a decrease in job opportunities. Therefore, the most likely resultant effect of such a decline in profit margin is an increase in unemployment.
Question 30 Report
The part of income after tax that is not consumed is defined as
Answer Details
The part of income after tax that is not consumed is defined as saving. Saving refers to the portion of income that is not spent on immediate consumption and is instead put aside for future use.
When we receive our income, we typically have various expenses to cover, such as bills, groceries, and entertainment. After deducting these expenses and taxes, we are left with a certain amount of money. If we choose not to spend this remaining amount and instead keep it for later, we are saving that money.
Saving is important because it allows us to build up financial security and prepare for unexpected expenses or future goals. It can also be used for long-term investments, such as buying a house or planning for retirement.
In summary, saving is the part of our income that we choose to set aside rather than using it immediately for consumption.
Question 31 Report
The number of people who are qualified to work and who offered themselves for employment are called
Answer Details
The correct term for the number of people who are qualified to work and who offer themselves for employment is the working population.
The working population refers to the subset of the total population that is actively engaged or seeking employment. It includes individuals who are qualified, available, and willing to work. This encompasses both employed individuals and those who are actively looking for work, such as job seekers.
The working population is an important measure for understanding the labor market. It helps policymakers, businesses, and economists in assessing the job market's health and determining factors such as employment rates, labor force participation, and unemployment rates.
Options like "mobility of labor" and "migrant labor" focus on the movement of workers between different locations, which is a related concept but not the same as the total number of qualified individuals available for employment. "Labor turnover" refers to the rate at which workers leave and join a particular company or industry, which is also not synonymous with the working population as a whole.
Therefore, the working population is the term that correctly describes the number of qualified individuals who are available for employment.

Question 35 Report
An increase in nominal income without increase in price will result to
Answer Details
An increase in nominal income without an increase in prices will result in an **increased real income**. Nominal income refers to the amount of money a person earns or receives in a given period, without taking into account changes in prices. On the other hand, real income takes into consideration the effects of inflation by adjusting for changes in prices. When nominal income increases but prices remain constant, it means that the purchasing power of an individual's income has increased. In other words, they can afford to buy more goods and services with the same amount of money. This increase in purchasing power leads to an increase in real income. For example, let's say a person's nominal income is $1,000 per month, and the prices of goods and services they consume also remain constant. If their nominal income increases to $1,200 per month, without any increase in prices, they now have an additional $200 to spend on other things. This additional purchasing power translates to an increase in their real income. It is important to note that an increase in nominal income without an increase in prices does not necessarily lead to an **increased GDP** or a **decreased GNP**. GDP (Gross Domestic Product) measures the total value of goods and services produced within a country's borders, while GNP (Gross National Product) measures the total value of goods and services produced by a country's residents, including those produced abroad. The increase in real income of individuals does not automatically impact the overall production levels captured by GDP or GNP.
Question 36 Report
The quantity of commodity a consumer is willing and able to buy at a particular time is called
Answer Details
The quantity of a commodity that a consumer is willing and able to buy at a particular time is called demand.
Demand refers to the consumer's desire or willingness to purchase a specific product or service at a given price and at a given time. It represents the customer's intent to buy and the amount they are willing to buy at various price levels.
It is important to note that demand is not just about the desire for a particular item, but also the consumer's ability to pay for it. For example, someone may wish or desire to buy a luxury car, but if they do not have the financial means to afford it, their demand for that car is limited.
In summary, demand is the quantity of a commodity that a consumer is both willing and able to buy at a given time, reflecting their desire for the product and their ability to pay for it.
Question 37 Report
If commodities X and Y are substitute, their cross elasticity of demand will be
Answer Details
If commodities X and Y are substitutes, the cross elasticity of demand between them will be positive.
Cross elasticity of demand measures how the quantity demanded of one commodity changes in response to a change in the price of another commodity. When two commodities are substitutes, they serve similar purposes and are considered as alternatives to each other. For example, if the price of commodity X increases, some consumers may switch to commodity Y as a substitute, causing an increase in the quantity demanded of commodity Y.
The positive cross elasticity of demand reflects this relationship. It means that an increase in the price of commodity X will lead to an increase in the demand for commodity Y, and vice versa. On the other hand, if the cross elasticity of demand were negative, it would indicate that the two commodities are complements, meaning that they are used together and a change in the price of one would result in an opposite change in the demand for the other.
Therefore, in the case of substitute commodities, the cross elasticity of demand will be positive.
Question 38 Report
When a kilogram of carrot is #8.00, 20 kilograms are demanded and when the price decreased to #6.000 per kilogram, 30 kilograms are demanded. The elasticity of demand equals to
Answer Details
To calculate the elasticity of demand, we need to compare the changes in price and quantity demanded.
First, let's calculate the percentage change in price:
% change in price = ((new price - old price) / old price) x 100
% change in price = ((6 - 8) / 8) x 100
% change in price = (-2 / 8) x 100
% change in price = -25%
Next, let's calculate the percentage change in quantity demanded:
% change in quantity demanded = ((new quantity demanded - old quantity demanded) / old quantity demanded) x 100
% change in quantity demanded = ((30 - 20) / 20) x 100
% change in quantity demanded = (10 / 20) x 100
% change in quantity demanded = 50%
Now, let's calculate the elasticity of demand:
Elasticity of demand = % change in quantity demanded / % change in price
Elasticity of demand = 50% / -25%
Elasticity of demand = -2
The elasticity of demand is -2.
Explanation:
The negative sign in the elasticity of demand (-2) indicates that the demand for carrots is price elastic. This means that a decrease in price by 1% will lead to a more than proportionate increase in quantity demanded by 2%. In simpler terms, when the price of carrots decreased by 25%, the quantity demanded increased by 50%.
Therefore, the elasticity of demand is -2, which means that the demand for carrots is price elastic.
But since price elasticity is always represented with a positive number, the answer is 2
