1. Suppose that the equilibrium price of an article is N5.00 but government fixes the price by law at N4.00, the supply will be A. The same as the equilibrium supply B. Greater than the equilibrium supply C. Less than the equilibrium supply D. Determined later by the government E. None of this The answer is C Note: The law of supply states that the higher the price the higher the quantity supplied and vice versa. So when price falls supply will also fall that make us pick option C because the supplier is willing to supply at a higher price rather than a lower price See the you tube link for understanding see the you tube link for proper understanding: 1978,Q1
  2. A budget deficit means A. that a country is buying more than it is selling B. that a country is selling more than it is buying C. a government is spending more than it takes in taxation D. a government is spending less than it takes in taxation E. a government is spending as much as it takes in taxation The correct answer is C Notes: This question is on public finance. There are three types of budget first is surplus budget this is when the revenue of the government is greater than the expenditure during a fiscal year. The question can be twisted as when the difference between government revenue and expenditure is positive what type of budget is the country operating? of course it is a budget surplus. Next is the budget deficit which is a type of budget in which government revenue is less that its expenditure or you say the difference between revenue and expenditure is negative. Finally the balance budget where revenue and expenditure are equal or the difference between revenue and expenditure is zero. so option D is budget surplus and option E is balance budget.
  3. the answer is option B. 1978, copy/click the link: Q3
  4. When elasticity is zero, the demand curve is A. perfectly elastic B. Perfectly inelastic C. concave D. downward sloping E. Circular The answer is B This testing your knowledge of price elasticity of demand. Options C and E are out of it. Option D is the demand curve or you indifference curve. Perfectly elastic coefficient is infinity and the graph is a straight horizontal line which implies if price changes the consumers can clear the available unity of the commodity. Perfectly inelastic coefficient is zero. This implies that no matter how cheap the commodity is the consumers won’t change the units purchased and the graph is a vertical straight line.

5. The following is not a reason for the existence of small firms A. Scale of production is limited by market size B. Expansion bring diminishing returns C. large firms can cater for wide markets D. small firms can provide personal services E. All of the above

The correct answer is B. it is not all firms that witness diminishing returns. It is only firms in the agricultural sector that witness diminishing returns.

Notes: Diminishing returns holds in the short run. It is sometimes called the law of variable proportion. The law that holds in the long run is the law of return to scale.

The short run is a period where there is at least one fixed factor (Land) other factors of production are variable. The long run is a period where all factors of production are variable (This is when the firm is undergoing expansion)

6. Inferior goods are defined as in Economics as A. whose quality is low B. Consumed by the poor C. whose consumption fall when consumer income increases D. Which satisfy only the basic needs E. None of the above

The correct answer is C. Inferior goods are goods whose demand or consumption fall as income increases or you say commodities whose demand have negative relationship with the consumer’s income

Note: Interpretation of YED (income elasticity of demand) is as follows


  1. Coefficient of YED is positive the commodity is a normal commodity. If the value of coefficient is less than 1 (E<1) the commodity is a necessity and if the coefficient is greater than 1 (E>1) the commodity is a luxury.
  2. Coefficient of YED is negative the commodity is an inferior commodity. A normal commodity is a commodity whose demand increases as income increases

Notes:  commercial bank creates money by advancing loans this is what is known as the money multiplier which is given as A × 1/R where a is the initial deposit and R is the reserve requirement. For example if the initial deposit in a bank is 1000 NGN and the reserve ratio is 10% what is the total credit created by the bank from the initial deposit?

Find the multiplier 1/0.1 which give 10 (recall that 0.1 = 10/100)

Total money created is 10 × 1000 which 10,000 NGN

The correct option is A. Note: when you see a question about the response of demand/supply or the effect on demand/supply on of a change in a variable (price of the commodity, income or price of other commodities) it is most likely it is on elasticity. If the variable causing the change is the price of the commodity it is price elasticity of demand (PED), if it is income of the consumer it is income elasticity and if it is the price of another commodity then it is cross elasticity of demand (CED).

17. Which of the following can be regarded as a liability of the commercial bank? A. Advances B. Deposits C. Treasury bills D. over drafts E. cash

The answer is B. the deposits with commercial banks is not for the bank but for the public and if the bank cannot present it when requested by the account holder then the customer can sue the bank.

B is correct. The major reason why economics is important because it helps to allocate scarce resources. The study of economics involves how man faces economic problems and how this problems are resolved.

34. Opportunity cost is a term which describes   A. the initial cost of setting up a business venture B. cost of one product in terms of forgone production of others C. the monetary equivalent of utility of a commodity D. costs related to an optimum level of production E. implicit cost

The answer is B. these are the alternatives forgone, that is the wants left unsatisfied because of limited resources. Note that the opportunity cost is also called true cost or real cost. Also opportunity cost is the next best alternative. For example the opportunity cost of a pencil cannot be a house because the money of a pencil cannot buy a house.

35. If the consumer demand for product X increases as the price of product Y decreases, we can be fairly certain that A. X and Y are complementary goods B. X and Y are substitute goods C. X and Y are independent goods D. X and Y are jointly demanded supplied E. X and Y Rare inferior goods

The correct answer is A. The ideology here is to ascertain if the final answer will be negative or positive. The fact that the price decreases will give a negative sign (% change in price) and the numerator is positive because it increases. Therefore we have a negative sign at the bottom and a positive sign at the top.

Let us do some mathematics reminder

+ × – = –                          + ÷ – = –               

– × + = –                          –  ÷ + = –

– × – = +                         +  ÷ + = +

+ × + = +                       –  ÷ – = +

Simple summary is that for multiplication and division give the same answer. Note if the signs are the same it will be plus and if the signs are different it will be minus.

Therefore from the interpretation of the coefficients of cross elasticity the commodities are complementary.

The optimum population of a country is reached when A. all factors of production have been fully employed B. the productive effort per man at its highest with a given volume of resources C. the total population of a country increases D. the natural resources of a country increases E. the working population of a country increases

The correct option is A. there are three categories of population first under population which is a type of population in which the resources in the country is more than the people or you say that the resources are underutilized or under employed. Next is the optimum population which is a type of population in which the resources can cater for the population of the country or equal to the resources available is equal to the population, and finally over population where the people are more than available resources

47. In economics, production is complete when A. goods are produced in the factory B. goods are sold to the wholesaler C. goods and services are produced by the government D. prices are fixed for goods and services E. goods and services finally reach the consumer

48. A rational consumer will adjust his spending pattern so that A. he buys only the one item that gives him the most the most total satisfaction B. the marginal utility he gets from the last unit of each item is the same C. the marginal utility he gets from the last naira spent on each item is the same D. the total utility he gets from each item is the same E. the total amount of money spent on each item is the same

The answer C. This is the utility maximization condition. A rational consumer is a consumer that consumes goods that will give him the maximum satisfaction. For utility the extra satisfaction (marginal utility) must be equal to the last naira spent by the consumer. Therefore the utility maximization condition can be written mathematically as MUX  =  PX  this is when a consumer is consuming one commodity which is called monomania but if he is consuming two commodities the utility maximization condition becomes:

                                   MUX =  MUY

                                    PX          PY

50.  The numerical measure of elasticity is

A. % ∆ in Q       B.  Change in Q       C.    % ∆ in P       D. Change in P      E. Change in P plus change in Q     

      % ∆ in P                Change in P              % ∆ in Q             Change in Q                     change in Q

The correct answer A. recall that the definition of elasticity is the degree of responsiveness of demand/supply to changes in factors affecting or determinants of demand. The fact that we have included degree we must put percentage. Note we can’t use 360 degree here because it relates more to temperature which is scientific but percentage is more appropriate for monetary comparison
