KENDRIYA VIDYALAYA SANGATHAN, ERANAKULAM REGION SAMPLE PAPER- 0- ECONOMICS-CLASS XII ANSWER KEY Q.No Value point Marks PPC is concave to origin because of increasing Marginal rate of Transformation Change in price of a commodity causes movement along the demand curve Total product will be increasing at decreasing rate. Rent for building, Minimum Telephone bill 5 Under perfect competition (a) Unlimited wants (b) Limited Resources (any two points with explanations) 7 Elasticity of demand= Since quantity demanded doubles,% change in quantity demand is 00% % change in price is 50% Ed= = 8 Output MR TR Price 0 0 5 9 MC is an addition made to total cost by one more unit of output is produced. AC is per unit cost of production of an output. The relationship between MC and AC as follows: When MC< AC, then AC falls When MC=AC, then AC is minimum When MC>AC, then Ac rises, output TC MC AC 5 7 9 MC<AC MC=AC MC>AC.5 AC falls AC Min.. AC Rises 0 Price discrimination under monopoly is the practice of charging different prices from different customers at the same time for the same product. Eg: Indian Railway, KSEB Selling cost is very essential under monopolistic competition, it is the expenses incurred on marketing,, sales promotion and advertisement of a product. The law od diminishing marginal utility states that the marginal utility derived from the consumption of a commodity must diminish as more and more unit of that commodity are consumed at point of time. Units of commodity Total Utility Marginal Utility 00 00
5 80 0 80 00 00 In case the consumer consumes two or more than two commodities his equilibrium will be determined by the law of equi- marginal utility. It states that a consumer spends his money income on different goods in such a way that the ratios of marginal utility of commodity and its price are equal for all commodities i.e. = =MUm Technological changes: Advanced and improved technology of production will increase the supply of a product. Technological degradation or outdated technology will reduce the supply of a product. Change in price of factor inputs: Fall in prices of factor inputs will increase the supply of a product. Rise in prices of factor inputs will decrease the supply of a product. Change in price of related goods affect the quantity demanded of a commodity.. In the case of substitute good,fall in price will decrease the quantity demand and rise in price will increase the quantity demand of a commodity eg;tea & coffee. In the case of complementary good, fall in price will increase the quantity demand and rise in price will decrease the quantity demand of a commodity. Eg: Pen &Ink (a) An indifference curve always slopes downward. (b) Indifference curves are convex to the origin. (c) Indifference curve can never intersect each other. (Three points with explanation) 80 0 0 0 0 Conditions of consumer s equilibrium (a) Budget line should be tangent to Indifference curve i.e. MRS XY = (b)indifference curve should be convex to the point of origin at equilibrium point. 5 Producer is said to be in equilibrium when he is earning maximum profit. Necessary conditions are:.mr=mc.mc>mr after MC=MR output level as long as MC is less than MR,It is profitable for the producer to go on producing more because it adds more to profits. When MC> MR after equilibrium, it means producing more will lead to decline in profits. 7
Equilibrium price is the price where demand for a commodity is exactly equal to its supply Price(Rs) Demand(units) Supply(units) Remarks 5 50 > 0 > 0 = 0 < 0 < 0 0 0 0 50 Excess demand = Equilibrium Excess supply Equilibrium price is Rs. Where both market demand and market supply are equal If Demand > Supply It is the situation of excess demand, price of the commodity will be pushed up till demand= supply If Demand< Supply, It is the situation of excess supply, price of the commodity will be pushed down till demand = supply 7 Involuntary unemployment occurs when those who are able and able to work at the prevailing wage rate do not get job. 8 ΔY= K x ΔI K = = = Δ I = 000 Δ Y = X 000 = 000 9 Excess of revenue expenditure over revenue receipts. 0 Total volume of money held by the public at a particular point of time. Government budget is a detailed financial statement of the estimate of government receipts and government expenditure during a financial year. Net value added at market price: (iii X ii +iv v vii i) (0 X900) + 000-800 0000 700 = Rs.5500 Money function as a unit of measure, providing a common measure of the value of goods and services being exchanged. Money enables both the supplier and the purchaser of the good to make decisions about how much of the good to supply and how much of the good to purchase. (i) Intermediate expenditure since it reoccurs every year, it does not help in further production and it is a part of depreciation. (ii) intermediate expenditure, since it will help in further production, but it may have to be done again and again. 5 Whether machine is final good or intermediate good depends upon how it is being used. If the machine purchased by a household, then it is a final good. If the machine purchased by a firm for its own use, then also final good. If the machine purchased by a firm for resale in the market, then it is an intermediate good. When price of foreign currency rises its demand falls because of inverse relationship between exchange rate and demand for foreign exchange. When price of foreign currency rises, imports become dearer, so imports decreases and demand for foreign currency falls. There is direct relationship between foreign exchange rate and supply of ½ ½ ½ ½ 8
foreign exchange. When price of foreign exchange rises domestic goods became cheaper,so exports increase and hence supply of foreign currency increases. 7 LRR is the minimum fraction of the total deposits which is legally compulsory for a commercial bank to keep as cash with themselves as per the central Bank s guidelines. it has two components: (i) Cash reserve Ratio; Minimum amount of funds that a commercial bank has to maintain with RBI. (example (ii) Statutory Liquidity Ratio: Minimum reserve of assets with RBI either fixed or liquid. (example) The central Bank act as Banker s Bank in various respects: (a) provides financial assistance to the commercial a banks. (b) Act as a custodian of cash reserve ratio (c) As a clearing agent (d) As a lender of last resort. (X=) 8 Deficient demand is situation in which current aggregate demand falls short of aggregate demand required to establish full employment. Deflationary gap is the gap by which the extent to which current aggregate demand falls short of aggregate demand required to establish full employment equilibrium. Diagram showing deflationary gap. 9.Take any measure to reduce the import bill of the country.. Take necessary steps to increase inflow of foreign exchange to the country (or any two measures to reduce deficit in BOP) 0 Revenue expenditure: Expenditure of the government which does not result in creation of any asset or reduction in liability, it is financed out of revenue receipt. Capital expenditure: Expenditure of the government which leads to create an assets or reduction in liabilities. It is financed out of borrowing from the public of foreign government. a.repayment of loans: Capital expenditure, it reduces the liability of government. b. expenditure on power generation: capital expenditure, it creates asset to the government. c. Pension payment: revenue expenditure,it neither creates assets nor reduces liability d.
