Q. 2. (A)
      (1) (A) Identified concept : Individual demand
            (B) Explanation of concept : Individual demand is the demand by a single
                consumer in a market for a given commodity at a given price and time.
      (2) (A) Identified concept : Perishable goods
            (B) Explanation of concept : To avoid losses, perishable commodities such as

Q. 3. (1) The importance of microeconomics can be explained with the help of the following
          points :
          (1) Helpful in explaining price determination : Microeconomics helps in
              explaining the price determination of goods and services as well as factors of
              production.
          (2) Helpful to understand the working of free market economy : Microeconomics
              helps to understand how free market economy works and gets regulated by
              demand and supply principles. Microeconomics helps producers to take
              business decisions about what to produce, how to produce, how much to
              produce, etc. at individual levels. There is no intervention by government or
              any other agency in this decision making process.
          (3) Helpful in foreign trade : Microeconomics is useful in studying the aspects
              related to foreign trade such as effects of tariff, determination of exchange rate,
              gains from international trade, etc.
          (4) Helpful in economic model building : Microeconomics helps in understanding
              complex economic situations with its variety of models. Many terms, concepts,
              terminologies, tools of economic analysis of microeconomics have valuably
              contributed to the science of economics.
          (5) Helpful to businessmen in taking business decisions : Microeconomics help
              businessmen in formulating prices of products or services, minimizing the cost
              of production, analysing profitability of investment, attainment of maximum
              productivity, etc. It also helps businessmen in demand forecasting.
          (6) Useful to government : Microeconomics is useful to government in framing
              economic policies such as tax policy, public expenditure policy, price policy,
              etc. Microeconomics also guides government in attaining the goal of efficient
              allocation of resources and economic welfare of society.
          (7) Basis of welfare economics : Microeconomics provides explanation for the
              conditions of economic welfare. It explains how the maximum welfare of
              people in society can be achieved by avoiding wastage of resources.
          Thus, microeconomics has many theoretical and practical importance as well as
          uses.
          (Note : Write any four points in the answer.)
      (2) The significance of index numbers in economics can be explained as follows :
          (1) Helpful in framing suitable policies : Index numbers provide guidelines to
              policy makers in framing suitable economic policies. Index numbers are helpful
              in framing the economic policies such as agricultural policy and industrial
              policy. Index numbers also help in the fixation of wages and dearness allowances
              in accordance with the cost of living, etc.
4                     NAVNEET PRACTICE PAPERS : STD. XII (COMMERCE)
    (2) Helpful in studying trends and tendencies : Index numbers are widely used
        to measure changes in various economic variables such as production, prices,
        exports, imports, etc. over a period of time. For example, by examining the
        index of industrial production for the last five years, important conclusions
        about the trend of industrial production, i.e. whether the industrial production
        shows an upward tendency or a downward tendency can be drawn.
    (3) Helpful in forecasting future economic activity : Index numbers helps in
        making predictions on the basis of analysis of the past and present trends in
        the economic activities. For example, by examining the data pertaining to
        exports of alphonso mangoes from the year 2009 to 2014 and from the year
        2014 to 2019, if it is noticed that the export of alphonso mangoes has been
        increasing, it can be predicted that an increase in export will continue in future.
    (4) Helpful in measurement of inflation : Index numbers are also used to
        measure changes in the price level from time to time. The measurement of
        inflation enables the government to undertake appropriate anti-inflationary
        measures. For example, there is a legal provision to pay the D.A. (dearness
        allowance) to the employees in organised sector on the basis of changes in
        Dearness Index. Thus, with the help of the Dearness Index, the government
        can increase the D.A. from time to time.
    (5) Useful to present financial data in real terms : Rise in money supply over
        a period of time leads to inflation in an economy. Inflation has its effects on
        various economic variables such as total production, national income, price
        level, wage level, etc. Index numbers can exclude the effects of inflation by
        deflating the values of these various economic variables on the basis of their
        constant prices. Thus, index numbers can measure the changes in the values of
        various economic variables in real terms.
    (Note : Write any four points in the answer.)
(3) The determinants of supply are as follows :
    (1) Price : Price is the most important factor influencing the supply of a commodity.
        Price and supply are directly related to each other, i.e. more is supplied at a
        higher price and less is supplied at a lower price.
    (2) State of technology : Technological improvements reduce the cost of
        production, which lead to an increase in production and supply. On the other
        hand, traditional and outdated technology reduces the supply.
    (3) Cost of production : Cost of production and supply have inverse relation. For
        example, if the price of factors of production increases, the cost of production
        also increases. This in turn decreases the profit margin of a supplier and this
        in turn decreases the supply. On the other hand, fall in the cost of production
        increases the supply.
         SOLUTIONS TO NAVNEET PRACTICE PAPERS : STD XII (ECONOMICS)                      5
        (4) Infrastructural facilities : Infrastructure in the form of transport,
            communication, power, etc. influences the production process as well as supply.
            Inadequate infrastructural facilities decrease the supply and vice versa.
        (5) Government policy : Government policies on taxation, subsidies, industrial
            policies, etc. may encourage or discourage production and supply depending
            upon government policy measures. For example, government subsidies tend to
            increase the supply.
        (6) Natural conditions : The supply of agricultural products depends on the
            natural conditions. For example, a good monsoon and favourable climatic
            condition will produce a good harvest, so the supply of agricultural products
            will increase. On the other hand, unfavourable climatic conditions will lead to
            poor harvest and thus, to a decrease in supply of agricultural goods.
        (7) Future expectations about price : If the prices are expected to rise in the
            near future, the producer may withhold the stock. This will reduce the supply
            though the current prices are high. On the other hand, if the prices are expected
            to fall in the near future, the producer sells more though current prices are low.
        (8) Other factors : Other factors like nature of the market, relative prices of other
            goods, export and imports, industrial relations, availability of factors of
            production, etc. determine the supply of various goods. For example, adequate
            availability of factors of production increases the supply. On the other hand,
            shortage of factors of production decreases the supply.
        (Note : Write any four points in the answer.)
    (4) The following are the problems of capital market in India :
        (1) Financial scams : Financial scams are on the rise in the Indian capital market.
            Rising financial scandals have increased the distrust of the general public and
            as a result, investors’ confidence in investing in the capital market has waned.
            As a result, capital markets face irreparable losses in the form of declining
            public confidence.
        (2) Insider trading and price manipulation : Some individuals have access to
            confidential information of companies. Such individuals, for personal gains,
            buy and sell securities on the basis of the unpublished confidential information
            of companies. Some individuals deliberately raise or lower the price of shares
            by buying and selling shares of certain companies among themselves for
            personal gain. Such illegal transactions are adversely affecting the smooth
            functioning of the capital market of India.
        (3) Inadequate debt instruments : In the capital market of India, debt instruments
            include bonds, debentures, etc. Due to narrow investor base, high cost of
            issuance, restrictions on entry of small and medium enterprises into the capital
            market, etc., there is relatively lower trading in debt securities.
6                   NAVNEET PRACTICE PAPERS : STD. XII (COMMERCE)
    (4) Decline in the volume of trade : Capital market investors can trade online.
        As a result, capital market investors in various parts of the country prefer to
        invest in securities listed in premier stock exchanges like in the Bombay Stock
        Exchange and in the National Stock Exchange. As a result, there has been a
        sharp decline in trade volume on regional stock exchanges in India.
    (5) Lack of information efficiency : If the company’s current stock price
        incorporates all the information about the company, then a market is said to be
        informationally efficient. However, the efficiency of information in the Indian
        stock market is relatively low compared to other developed countries. As a
        result, investors do not get the expected return on investment and thus lose
        faith in the capital market.
    (Note : Write any four points in the answer.)
(5) The features of monopolistic competition are as follows :
    (1) Fairly large number of sellers : Although the number of sellers in a
        monopolistic competition is large, it is still smaller than that in a perfectly
        competitive market. Since number of sellers is large, each seller has a limited
        control over the market supply. However, each seller has monopoly over his
        brand. Thus, in monopolistic competition, each producer enjoys an element of
        monopoly on one hand and on the other, they have to face competition from
        sellers selling close substitutes.
    (2) Fairly large number of buyers : In monopolistic market, there are fairly
        large number of buyers. Consequently, no single buyer can influence the price
        of the product by changing his individual demand.
    (3) Product differentiation : Product differentiation is the main feature of
        monopolistic competition. In monopolistic competition, there are many firms
        producing differentiated products. In this market, the product of each firm is
        in some way differentiated from the product of every other firm in the market.
        Product differentiation may take the form of brand names, trademarks,
        peculiarity of package or container, shape, quality, cover, design, colour, etc.
        This means that the product of each firm may find close substitutes and the
        cross elasticity of demand for each firm’s product is very high. For example,
        mobile handsets, soaps, toothpastes, two wheelers, etc.
    (4) Free entry and exit : Under monopolistic competition, there is freedom of
        entry and exit. The new firms are free to enter the market if there is opportunity
        of earning profit. Similarly, existing firms can exit the market, if they find it
        difficult to survive due to possibility of losses.
    (5) Selling Cost : Selling cost is a peculiar feature of monopolistic competition.
        Selling cost refers to the cost incurred by the firm to create more demand for
        its product and thus increase the volume of sales. Selling cost includes
         SOLUTIONS TO NAVNEET PRACTICE PAPERS : STD XII (ECONOMICS)                     7
              expenditure on advertisements, radio and television broadcasts, hoardings,
              exhibitions, window display, free gifts, free samples, etc.
          (6) Close substitutes : In monopolistic competition, goods have close substitutes
              to each other. For example, different brands of cold drinks, biscuits, tea, etc.
          (7) Concept of group : Under monopolistic competition, Chamberlin introduced
              the concept of ‘Group’ in place of industry. Industry means the number of
              firms producing identical products. On the other hand, a ‘Group’ means a
              number of firms producing differentiated products which are closely related to
              each other. For example, group of firms producing medicines, automobiles, etc.
          (Note : Write any four points in the answer.)
Q. 4. (1) I disagree with this statement.
          Reasons :
          (1) Index numbers measure changes in the price level as well as changes in stock
              market prices, cost of living, industrial and agricultural production, exports and
              imports, etc.
          (2) For example, Labour Productivity Index Number measures the general changes
              in the labour productivity over a period of time.
          (3) Consumer Price Index Number, Wholesale Price Index Number, Index of
              Service Production, Human Development Index Number, etc., are the special
              purpose index numbers measuring the changes in various economic variables
              over a period of time.
          Thus, index numbers do not measure changes in the price level only, but also
          measure changes in many other economic variables.
      (2) I agree with this statement.
          Reasons : The following are the types of monopoly :
          (1) Private monopoly : Private monopoly refers to sole ownership of the supply
              of goods or services by the private firm or individual. The main objective of
              private monopoly is earning the maximum profit. For example, Tata Group.
          (2) Public monopoly : Public monopoly refers to sole ownership of the supply of
              goods or services by the government. The main objective of public monopoly
              is not to earn the profit but to provide the maximum welfare to the society. For
              example, Indian Railways.
          (3) Legal monopoly : The monopoly that emerges on account of legal provisions
              like patents, trade mark, copy rights, etc. is called legal monopoly. In a legal
              monopoly, the law forbids the potential competitors to imitate the design, form
              or shape of a product which is registered with a particular trade mark. If any
              firm violates the rights of the trade mark, legal action is taken against them.
              For example, Amul’s products.
8                     NAVNEET PRACTICE PAPERS : STD. XII (COMMERCE)
    (4) Natural monopoly : The monopoly created on the basis of natural conditions
        like climate, rainfall, specific location, etc. is known as natural monopoly. For
        example, monopoly created by the state of Punjab in the production of wheat
        due to favourable climatic conditions and fertile soil.
    (5) Simple monopoly : It is a type of monopoly, in which a monopolist charges
        consumer wise, place wise, time wise and use wise uniform price for the same
        product.
    (6) Discriminating monopoly : It is a type of monopoly, in which a monopolist
        charges consumer wise, place wise, time wise and use wise different prices for
        the same product. For example, In India, the electricity charges are comparatively
        less for its domestic use and high for its commercial use.
    (7) Voluntary monopoly : It is a type of monopoly where some monopolists
        voluntarily come together and form a group to avoid cut-throat competition.
        This facilitates them to maximise the profit. For example, Organisation of
        Petroleum Exporting Countries (OPEC).
    (Note : Write any three points in the answer.)
(3) I disagree with this statement.
    Reasons :
    (1) Macroeconomics does not study the individual economic unit such as particular
         consumer, individual demand, particular seller, individual supply, price
         determination of particular good, etc.
    (2) Microeconomics studies individual economic units and deals with how a
         particular consumer attain maximum satisfaction and how a particular producer
         attain maximum profit.
    (3) Macroeconomics studies the economic behaviour of aggregates, their functional
         relationship, their interdependence, their determination and causes of
         fluctuations in them.
    Thus, macroeconomics does not deal with the study of individual behaviour, rather
    it deals with the study of behaviour of aggregates.
(4) I agree with this statement.
    Reasons :
    (1) Foreign trade earns foreign exchange. The foreign exchange received can be
        used for various productive activities.
    (2) Foreign trade provides an opportunity for domestic producers to sell goods and
        services in the domestic market as well as export to the world market.
    (3) Encouragement of production and market expansion of indigenous goods and
        services encourages large scale investment in various industries in the country.
        Large investments increase employment levels and national income, leading to
        economic growth in the economy.
    Thus, trade is an engine of growth for an economy.

      (5) I agree with this statement.
          Reasons : The assumptions of the Law of DMU are as follows :
            (1) Rationality : The Law of DMU assumes that a consumer is a rational person
                and his behaviour is normal. The law assumes that a rational consumer wants
                to maximise his satisfaction.
            (2) Cardinal measurement : The Law of DMU assumes that utility can be
                measured in numbers. It also assumes that utility derived from each unit of a
                commodity can be compared.
            (3) Homogeneity : The Law of DMU assumes that units of a commodity consumed
                by a consumer are identical. It means all units of consumption of a commodity
                are perfectly uniform in respect of size, shape, taste, colour, quality, etc.
            (4) Continuity : The Law of DMU assumes that all units of consumption are
                consumed in quick succession, one after another. Thus law assumes that there
                is no time gap between the consumption of any two units.
            (5) Reasonability : The Law of DMU assumes that the size of unit of commodity
                of consumption is neither too small nor too big. Thus the law assumes that the
                size of unit of commodity of consumption is reasonable.
            (6) Constancy : The law assumes that income, taste, habits, preferences, likings,
                etc. of a consumer as well as the price of commodity remains constant.
            (7) Divisibility : The law assumes that the commodity consumed by the consumer
                is divisible.
            (8) Single want : The Law of DMU assumes that the commodity is used to satisfy
                only a single want, i.e. a want of consumption. Thus law assumes that a
                commodity is not used for any other use except consumption.
            (9) Constant marginal utility of money : The law assumes that when the
                consumer spends his income on a commodity, the utility of remaining money
                income remains the same as his total income.

Q. 5. (1)
            (1) Initially, at the first unit of consumption, the total utility and marginal utility
                are equal. From the second unit of consumption, the total utility increase with
                the diminishing rate. When the marginal utility becomes zero, the total utility
                is the maximum. When the marginal utility becomes negative, the total utility
                also starts diminishing.
            (2) When the marginal utility becomes zero, the total utility is the maximum. It is
                called the point of satiety. A rational consumer stops the consumption of a
                commodity at a point of satiety. Beyond a point of satiety, continuity in
                consumption gives dissatisfaction to the consumer.

            (1) The two sectors in a financial market are organised and unorganised sectors.
            (2) The unorganised money market includes unregulated entities such as money
                lenders, chit funds, and other informal financial intermediaries that carry out
                transactions outside the purview of government and regulatory bodies.
            (3) It is necessary to increase the presence of organised sector institutions in
                remote and interior parts of the country to ensure inclusive growth and
                development of the country.
Q. 6. (1) (A) Statement of the Law of Demand : According to Dr. Alfred Marshall,
          “Other things being equal, the amount demanded rises with a fall in price; and
          diminishes with a rise in price”.
            (B) Assumptions : The following are the assumptions of the Law of Demand :
                (1) Constant level of income : If there is rise in the income of a consumer,
                    demand for different goods and services tends to rise even at a higher
                    prices. In that case, the law becomes inapplicable. Therefore, to prove the
                    law, it is assumed that there is no change in consumer’s income.
                (2) No change in the size of population : Due to a rise in the size of
                    population, the demand for all goods and services tends to rise at their
                    constant prices. In such a situation, the Law of Demand becomes
                    inapplicable. Therefore, to prove the validity of the law, it is assumed that
                    the size and the composition of population remain constant.
                (3) No change in prices of substitute goods : Due to the availability of
                    cheaper substitute goods, the demand for a commodity in question tends to
                    fall at its existing price and vice versa. Therefore, the law assumes that there
                    is no change in the prices of substitute goods of a commodity in question.
                (4) No change in prices of complementary goods : If the prices of
                    complementary goods rise, the demand for a commodity in question tends
                    to fall at its existing price and vice versa. Therefore, the law assumes that
                    there is no change in the prices of complementary goods of a commodity
                    in question.
                 SOLUTIONS TO NAVNEET PRACTICE PAPERS : STD XII (ECONOMICS)                      11
            (5) No expectations regarding future price : If a consumer anticipates a fall
                in price of the commodity in the near future, the demand for the commodity
                in question falls at the present price and vice versa. Therefore, the law
                assumes that consumers do not have any expectations regarding rise or fall
                in the price of a commodity in the near future.
            (6) No change in tastes, habits, fashions : If consumer’s liking for a particular
                commodity increases, then the demand for such a commodity tends to rise
                even at a higher price and vice versa. In such circumstances, the Law of
                Demand does not hold good. Therefore, to maintain the validity of the law,
                it is assumed that there is no change in tastes, habits, preferences of the
                consumer.
            (7) No change in government policy : Rise in the taxes leads to decrease in
                the disposable income of the consumer. This in turn decreases the demand
                for goods and services at their current prices and vice versa. Therefore, to
                prove the law, it is assumed that there is no change in government’s
                taxation policy.
        (Note : Write any six points in the answer.)
     (2) (A) Ratio Method :
            (1) Ratio Method of measuring elasticity of demand is developed by Dr. Alfred
                Marshall. This method is also known as arithmetic method or percentage
                method or proportional method of measuring elasticity of demand.
            (2) In this method, the elasticity of demand is measured by dividing the
                percentage change in the quantity demanded of a commodity by the
                percentage change in its price.
            (3) The formula used for the measurement of the elasticity of demand is as
                follows :
                       ΔQ P
                Ed =     × . Where,
                        Q ΔP
                (i) Δ Q = Change in the quantity demanded, i.e. Q1 − Q. (New
                demand − Original demand) (ii) Q = Original demand. (iii) Δ P = Change
                in the price, i.e. P1 − P. (New price − Original price) and (iv) P = Original
                price.
            (4) Ratio Method can be explained with the help of the following example :
                  Price and Demand of a
                                                Original        New            Change
                        Commodity
                 Demand (per day in units)     10 (Q)        9 (Q1)       01(ΔQ) Q1 − Q
                 Price (`)                     20 (P)        25 (P1)      05(ΔP) P1 − P
12                  NAVNEET PRACTICE PAPERS : STD. XII (COMMERCE)
              ΔQ P
       Ed =     ×
               Q ΔP
               1 20
       ∴ Ed =    ×
              10 5
       ∴ Ed = 0.4
       ∴ Ed<1.
       As the numerical value of the elasticity of demand is less than one, the
       demand is relatively inelastic in this example.
(B) Total Outlay Method :
   (1) Dr. Alfred Marshall has explained the outlay method of measuring elasticity
       of demand. This method is also called as total expenditure method or total
       revenue method. Total expenditure means Price × Quantity demanded. In
       this method, the elasticity of demand is measured by comparing the change
       in the total expenditure on a commodity in response to a change in the
       price of a commodity. This method can be explained with the help of the
       following schedule :
                                   Demand        Total
                                                               Elasticity of
       Commodity Price (`) (per day in           Outlay
                                                                Demand
                              units)               (`)
                    10          6                   60            Ed < 1
          ‘A’
                    20          5                  100     (Relatively inelastic)
                    30          4                  120            Ed = 1
          ‘B’
                    40          3                  120        (Unitary elastic)
                    50          2                  100            Ed > 1
          ‘C’
                    60          1                   60      (Relatively elastic)
   (2) Relatively inelastic demand : When a fall in the price of a commodity
       also leads to a fall in a total expenditure on a commodity and vice versa,
       then the demand is said to be relatively inelastic. For example, in the
       above schedule, in the case of commodity ‘A’, it can be seen that, as a
       commodity’s price falls from ` 20 to ` 10, the total expenditure on it also
       falls from ` 100 to ` 60. Similarly, as a commodity’s price rises from
       ` 10 to ` 20, the total expenditure on it also rises from ` 60 to ` 100. In
       the case of relatively inelastic demand, the price of a commodity and the
       total expenditure on a commodity are directly related to each other.
   (3) Unitary elastic demand : When a fall or a rise in the price of a commodity
       leads to no change in total expenditure on a commodity, then the demand
       is said to be unitary elastic. For example, in the above schedule, in the
       case of commodity ‘B’, it can be seen that, as a commodity’s price falls
    SOLUTIONS TO NAVNEET PRACTICE PAPERS : STD XII (ECONOMICS)                    13
                 from ` 40 to ` 30, the total expenditure on it remains same i.e. ` 120.
                 Similarly, as a commodity’s price rises from ` 30 to ` 40, the total
                 expenditure on it remains same i.e. ` 120.
             (4) Relatively elastic demand : When a fall in the price of a commodity
                 leads to a rise in a total expenditure on a commodity and vice versa, then
                 the demand is said to be relatively elastic. For example, in the above
                 schedule, in the case of commodity ‘C’, it can be seen that, as a commodity’s
                 price falls from ` 60 to ` 50, the total expenditure on it rises from ` 60 to
                 ` 100. Similarly, as a commodity’s price rises from ` 50 to ` 60, the total
                 expenditure on it falls from ` 100 to ` 60. In the case of relatively elastic
                 demand, the price of a commodity and the total expenditure on a commodity
                 are inversely related to each other.
     (3) Various sources of public revenue are as follows :
         (A) Tax Revenue : Tax sources of revenue of the government are as follows :
         (1) Direct Tax : A tax which is levied on the income or property of an individual
             and so in which the impact and incidence of tax is on same head is called direct
             tax. Income tax, property tax, etc. are the examples of direct tax.
         (2) Indirect Tax : A tax which is levied on goods and services and so in which
             the impact of tax is on one person (seller) and the incidence of tax is on
             another person (buyer) is called indirect tax. Goods and Services Tax, Custom
             Duty, etc. are the examples of indirect tax.
         (B) Non-Tax Revenue : Non-tax sources of revenue of the government are as
             follows :
         (1) Fees : Fee is paid by citizens in return for certain specific services rendered
             by the government. For example, education fee, registration fee, etc.
         (2) Prices of public goods and services : Modern governments sell various types
             of commodities and services to the citizens. A price is a payment made by the
             citizens to the government for the goods and services sold to them. For example,
             railway fares, postal charges, etc.
         (3) Special assessment : The payment made by the citizens of a particular locality
             in exchange for certain special facilities given to them by the authorities is
             known as ‘special assessment’. For example, local bodies can levy a special
             charge on the residents of a particular area where extra /special facilities of
             roads, energy, water supply, etc., are provided.
         (4) Fines and penalties : The government imposes fines and penalties on those
             who violate the laws of the country. The objective of the imposition of fines
14                   NAVNEET PRACTICE PAPERS : STD. XII (COMMERCE)
    and penalties is not to earn income, but to discourage the citizens from violating
    the laws framed by the government. For example, fines for violating traffic
    rules. However, the revenue from this source is comparatively limited.
(5) Gifts, grants and donations : The government may also earn some income in
    the form of gifts by the citizens and others. The government may also receive
    grants from the foreign governments and institutions for general and specific
    purposes. Foreign aid has become an important source of development finance
    for a developing country like India. However, this source of revenue is uncertain
    in nature.
(6) Special levies : The government levies duties on those commodities, the
    consumption of which is harmful to the health and well-being of the citizens.
    Like fines and penalties, the objective of special levies is not to earn income,
    but to discourage citizens from the consumption of harmful commodities. For
    example, duties levied on wine, opium and other intoxicants.
(7) Borrowings : The government borrows from the citizens in the form of
    deposits, bonds, etc. Government also gets loans from foreign governments
    and international organizations such as IMF, World Bank, etc. In modern times,
    loans are becoming more and more popular source of revenue for the
    governments.
