Section A answer 1 or 2 From it. That is answer 1 from section A and Four(4) From section B. We have solved
Choose 1 or 2 and any numbers from section B.



Qd= 40-4p

P: 10, 8, 6, 4, 2, 1
Qd: 0, 8,16, 24, 32, 36

When price = 10
Qd= 40-4(10)=0

When price= 8
Qd= 40-4(8)= 8

When price= 6
Qd= 40-4(6)= 16

When price= 4
Qd= 40-4(4) = 24

When price= 2
Qd= 40-4(2)= 32

When price= 1
Qd= 40-4(1)= 36


The slop of the curve indicate that the quantity demanded has negative correlation with price. The higher the price the lower the quantity demanded and vice versa

The conditions necessary for profit maximization are:
(i) Expand output if MR>MC
(ii)Reduce output if MC>MR
(iii)profit maximization adjust the date of production to the point where MR=MC

Frequency distribution table refers to the table that shows the items and the number of times they occur in a given distribution. We have grouped Frequency distribution table and ungrouped frequency distribution table. Eg of grouped distribution table is below

X: 2 | 3 | 5 | 6 | 8
F: 1 | 2 | 4 | 8 | 2

The table above shows the shows the score sheet of (17) students from maths test.

Standard deviation is the square of variation.
For example
SD= ∑f(x−x)²/∑f

Range: This refers to the highest number of items and the lowest in a given set distribution e.g from the above table
The Range= 8-2= 6

Table: This can be defined as the logical and systematic arrangements of data in rolls and columns . Eg Below are numbers of students and their scores in economics test.

​Number one f students: 2 | 6 | 8 | 9

Marks: 4 | 5 | 2 | 6


Labour can be defined as all human efforts of any kind, either skilled or unskilled, mental or manual, directed towards the production of goods and services. The rewards for labour as a factor of production comes in form of wages and salaries.

(i) Education and training : The level of education and training received by a worker will go a long way towards increasing the efficiency of labor. A well educated or well trained worker is in position to increase efficiency in his work.

(ii) Level of commitment and attitude: The level of commitment and attitude of a worker can affect the efficiency of labour. When a worker is highly committed to his job, this will result in efficiency of labour.

(iii) Efficient management : When efficient management is in place in any organization, it will go a long way towards improving efficiency of labour.

(iv) Efficiency of other factors of production: The efficiency of other factors of production like land, capital and entrepreneur when combined with efficient labour will increase productivity.

Tax: A tax is a compulsory levy imposed by a public authority against which tax payers cannot claim anything. It is not imposed as a penalty for only legal offence. The essence of a tax, as distinguished from other charges by the government, is the absence of a direct quid pro quo (i.e., exchange of favour) between the tax payer and the public authority.

Rates: Rates refer to local taxation, i.e., taxation levied by (or for) local rather than central government. Normally rates are proportional to the estimated rentable value of business and domestic properties. Rates are often criticised as being unrelated to income.


Surplus of the public sector units: The government acts like a business- person and the public acts like its customers. The government may either sell goods or render services like train, city bus, electricity, transport, posts and telegraphs, water supply, etc. The government also earns revenue from the production of commodities like steel, oil, life-saving drugs, etc.

Fine and penalties: They are the charges imposed on persons as a punishment for contravention of a law. The main purpose of these is not to raise revenue from the public but to force them to follow law and order of the country.

Gifts and grants: Gifts are voluntary contribution from private individu­als or non-government donors to the government fund for specific purposes such as relief fund, defence fund during war or an emergency. However, this source provides a small portion of government revenue.

Overpopulation is the discrepancy between the structure of the population and economic growth in a specific, country or group of countries under a specific economic. In other words it a system within a definite historical epoch.

(i)Lower Life Expectancy: While higher life expectancy is leading to increases in population in developed countries, lower life expectancy may be caused by the booms in population that less developed nations are experiencing.

(ii)Extinction: The effect of overpopulation on the Nigeria’s wildlife is also a major issue. As demand for land grows, so too does the destruction of natural habitats, such as forests.

(iii)Resource Consumption; As the population grows, so too does the amount
of resources needed to keep so many people alive. Food, water and fossil fuels are all being consumed at record rates, placing greater demands on producers and the planet itself.

(iv) Increased Intensive Farming As population has grown over the years, farming practices have evolved to produce enough food to feed larger numbers of people. However, intensive farming methods also cause damage to local ecosystems and the land , which may pose
problems in the future.

(v) Overpopulation Could Lead to a Food Shortage: While the population has been rising as a result of increased food production, this production has limits. More mouths need to be fed. Without an increase in food production that matches the rising population, deprivation and hunger will be on the rise and each individual will have access to smaller quantities of food

Inadequate educational system and High cost of education : The educational systems practised in Nigeria is adequate as special attention is paid to paper qualification to the detriment of job creation.As a result of high cost of acquiring education, many find it difficult to goto school and so end up with low paper qualification which may not permit them to get good employment

Lack of industrial growth and social amenities : Nigeria do not have industries that are capable of employing enough workers. Labour tends to be unavailable when there are no social amenities in the area. This leads to unemployment

Over population and Deficiency in demand : When a country’s population is too high, it tends to produce many workers and such workers may not have jobs to do, thereby leading to unemployment. An overall in demand for goods can lead companies to retrench workers.

Poor development plans and use of automated machines: Government does not normally put in place development plans that can create employment opportunities or take care of the unemployed. The use of automated machines in factories reduces the need for many workers and this lead to unemployment.


Geographical mobility of Labour: Geographical mobility of labour is one of major cause of unemployment in Nigeria. Due to certain circumstances labour finds it difficult to move from one geographical area to another and this results in unemployment.


Retailer may be defined as a trader who buys goods in small quantities from the wholesaler and sells in bits or units to the final consumer. In other words, a retailer is a merchant whose main business is to purchase goods from the wholesalers in small quantities and sell in smaller units directly to the final consumers.

(i)Information : Middlemen have a role in providing information about the market to the manufacturer. Developments like changes in customer demography, psychology, media habits and the entry of a new competitor or a new brand and changes in customer preferences are some kind of information that all manufacturers want.

(ii) Price Stability : Maintaining price stability in the market is another function a middleman performs. Many a time the middleman absorbs an increase in the price of the products and continues to charge the same old price to the customer.This is because of the intra middlemen competition. The middleman also maintains price stability by keeping his overheads low.

(iii) Promotion: Promoting the product and services in his territory is another function that the middlemen perform. Many of them design their own sales incentive programs aimed at building customer traffic at their outlets.

(iv) Title: Most middlemen take title to the goods and services and trade in their own name. This helps in diffusing the risks between the manufacturer and middlemen. This also enables middlemen being in physical possession of the goods, which enables them to meet customer demand at the very moment it arises.

(v) Financing : Middlemen finance manufacturers operations by providing the necessary working capital in the form of advance payments for goods and services. The payment is in advance even though credit may be extended by the manufacturer, because it has to be made even before the products are bought and consumed and paid for by the ultimate customer.

market is a place where buyers and sellers can meet to facilitate the exchange or transaction of goods and services. In Other examples include the black market, auction markets, and financial markets. In other words Markets establish the prices of goods and services that are determined by supply and demand.

(i)It’s a type of competition between others in the industry. This means more than one company is selling a similar product and competing in that market.

(ii)Everyone offers a similar product, but that product can’t be completely substituted. In other words, while other companies may sell goat’s milk soap, none of them are exactly like Betty’s soap because they do not contain all of the exact same ingredients.

(iii)All companies can enter or leave the industry when they want to. This means companies can enter in and sell goat’s milk soap when they think they can make money doing so. And, they can leave if they think there is no longer a market for the product.

(iv)Every company makes their own decisions about their products. So, they decide what price to sell their soap at and how many to make and sell. Because there’s such a demand for goat’s milk soap, Betty keeps a steady supply. And finally…

(v)There is product differentiation. Product differentiation means that companies try to distinguish or differentiate their products from others in the market so that their product is more enticing to customers.

balance of payments is a statement of all transactions made between entities in one country and the rest of the world over a defined period of time, such as a quarter or a year.

(i)Trade Policy Measures: Expanding, Exports and Restraining Imports: this method can be used to correct unfavorable balance payment by Trade policy measures to improve the balance of payments refer to the measures adopted to promote exports and reduce imports. Exports may be encouraged by reducing or abolishing export duties and lowering the interest rate on credit used for financing exports. Exports are also encour­aged by granting subsidies to manufacturers and exporters. Besides, on export earnings lower income tax can be levied to provide incentives to the exporters to produce and export more goods and services.

(ii)Expenditure and Switching Policies Devaluation: this significant method which is quite often used to correcting unfavorable balance of payment is the use of expenditure-switching policies. Expenditure switching policies work through changes in relative prices. Prices of imports are increased by making domestically produced goods relatively cheaper. In other words Expenditure switching policies may lower the prices of exports which will encour­age exports of a country. In this way by changing relative prices, expenditure-switching policies help in correcting unfavorable Balance of payment.

(iii)Exchange Control: it is all the exporters are ordered to surrender their foreign exchange to the central bank of a country and it is then rationed out among the licensed importers. None else is allowed to import goods without a licence. The unfavorable balance of payments is thus rectified or corrected by keeping the imports within limits. In other words No reliance can be placed on any single tool in unfavorable balance of payment.

(iv)Expenditure-Reducing Policies: The important way to correct unfavorable balance of payment is by reducing imports and thereby reduce unfavorable balance of payments is to adopt monetary and fiscal policies that aim at reducing aggregate expenditure in the economy. The fall in aggregate expenditure or aggregate demand in the economy works to reduce imports and help in solving the unfavorable balance of payments problem and corrected.
