Class 11 – Economics
Sample paper – 01 (2024-25)
Solution
- Section A
- (b) Both A and R are true but R is not the correct explanation of A.
Explanation: Both A and R are true but R is not the correct explanation of A. - (a) Price index = {tex}P1/P0 * 100{/tex}
Explanation: To calculate the Price Index, take the price of the Market Basket of the year of interest and divide by the price of the Market Basket of the base year, then multiply by 100. - (a) Negative correlation
Explanation: Because a negative value of correlation indicates an inverse relation. - (c) 140
Explanation: Here, P1=14, P0=10. Thus, Price index {tex}{\rm{P01 = }}\frac{{{\rm{P1}}}}{{{\rm{P0}}}}{\rm{ \times }}100 = \frac{{14}}{{10}} \times 100 = 140{/tex} - (b) Simple index number
Explanation: Simple index numbers grant equal importance to all items no matter what share it has. In other words, it considers each item to be equal with respect to the given variable. - (b) All of these
Explanation: Base year price, current year price and weights play important role in the construction of index number. - (b) All of these
Explanation: Statistics is used by the government as the role of government has increased and requires much greater information in the form of numerical figures to fulfil the welfare objectives. Statistics is also an indispensable tool for a proper understanding of various economic problems. Statistics is also useful for Industries as it helps in forecasting, production planning, quality control etc. - (d) Component Bar Diagram
Explanation: Component bar diagrams or charts, also called subdiagrams, are very useful in comparing the sizes of different component parts (the elements or parts which a thing is made up of) and also for throwing light on the relationship among these integral parts. For example, sales proceeds from different products, expenditure pattern in a typical Indian family (components being food, rent, medicine, education, power, etc.), budget outlay for receipts and expenditures, components of labour force, population etc. Component bar diagrams are usually shaded or coloured suitably. - (d) Aggregate price index
Explanation: A composite index number is a number that measures an average relative changes in a group of relative variables with respect to base whereas a simple index number is a number that measures a realive change in a single variable with respect to base.So, composite index number is based on an aggregate of items.

(a) It gives different weights to different items as per their importance.
(b) Its results are more reliable.
(c) It is more accurate and useful. - In this series, mid-values are given. The calculation of arithmetic mean involves the same procedure as in the case of exclusive series. We have to multiply the mid values with f and then find {tex}\Sigma fm{/tex} and divide it by {tex}\Sigma f.{/tex}
Calculation of Arithmetic Mean
Mid-Value (m) Number of Students (f) fm 5 5 25 10 7 70 15 9 135 20 10 200 25 8 200 30 6 180 {tex}\Sigma f = 45{/tex} {tex}\Sigma f m = 810{/tex} So, we get {tex}\Sigma fm = 810 {/tex} and {tex}\Sigma f = 45 {/tex}. Applying the formula of mean, we get
{tex}\overline { X } = \frac { \Sigma f m } { \Sigma f } = \frac { 810 } { 45 } = 18{/tex}
Hence, required arithmetic mean=18 marksOR
Increase in wages of each worker =Rs.20
Total increase in wages = 50 x 20 = Rs.1000
Total wages before increase in wages= 50 x 200 = Rs.10,000
Total wages after increase in wages=10,000+1000=Rs.11,000
New average wage= {tex}\frac { \Sigma X } { n } = \frac { 11,000 } { 50 } = Rs. 220{/tex}
Thus, the mean wage has increased by Rs.20.
The property of arithmetic mean which is reflected here is that if each observation of a series is increased or decreased by a constant, say k, then the arithmetic mean of the new series also gets increased or decreased by k. In this case, each item is increased by 20, so the mean also increases by 20. - We first find the lowest value in the given data and then the highest value. Then, in order to prepare inclusive frequency distribution, we need class size which is given as 7. Then, we form inclusive class intervals with respective frequency as visible in the given data. As in the question, the lowest value is 1 and the highest is 37. With the help of tally bar, inclusive frequency distribution will be derived.
The frequency distribution by the inclusive method of given data is shown below:Class Interval Tally Bar Frequency (f) 1-7 15 8-14 || 12 15-21 15 22-28 10 29-35 | 6 36-42 || 2 Total 60 - As per the question, year 2006 to 2011 and their respective profits are given Here, we take profit on the Y- axis and year on the X-axis. Before plotting the graph, we take a false baseline because the profit starts from 60 and there are very small fluctuations in the remaining values of profit, so we take a false base of 50 and then we take the scale as 1 cm = 5 (in thousands). The time series graph of given annual profit figures is shown below:
OR
General rules to construct a time Series graph
- Since time can never be in negative values, II and III quadrant are not used in making of time series graphs.
- Time period (week, Month, Year) is taken on X- Axis. And Variable under study is taken on Y-Axis.
- We start Y axis with Zero and decide the scales for both the axis.
- Different values are plotted on the graph.
- By joining these points, we get a time series graph.
Time series graph can be of three types:
- One Variable Graph.
- Two or more than two variable Graph.
- When False Base Line is used.
- Graphs of Different Units.
- These errors are a consequence which can be traced and may arise at any stage of inquiry, viz planning and execution of the survey and collection, processing and analysis of data.
some of the non-sampling errors are:- Errors in Data Acquisition It arises from the recording of incorrect responses.
- Non-response Errors It occurs, if an interviewer is unable to contact a person listed .
- Sampling Bias It occurs when the sampling plan is such that some members of the target population could not possibly be included.

- (b) Left
Explanation: Severe earthquake in a country leads to decline in both human as well as capital resources. As a result of which less resources are left for producing the goods. Thus decline in resources will lead to a leftward shift in the PPC. - (a) When demand for the commodity is perfectly inelastic
Explanation: When the demand for a commodity is perfectly inelastic the change in price will have no effect on the quantity demanded. The consumers do not change their demand due to the change in price. This usually is seen in case of necessities. Hence, the equilibrium quantity will be same the price might increase or decrease. - (a) MR will be constant but TR is a positively sloped straight line
Explanation: TR will increase with every increase in unit sold. So, it will be a positively sloped straight line. Whereas MR is the addition in revenue by selling one extra unit. Since price is constant, every extra unit sold will yield revenue equal to price. So, MR = Price and it will be a horizontal straight line. - (c) increasing
Explanation: MC is the rate of TC. If TC increases at increasing rate, MC must be increasing. - (d) A is false but R is true.
Explanation: The demand curve of the substitute good shifts to the right. Greater purchase of a commodity at its constant price points to a situation of increase in demand or a forward shift in the demand curve. - (d) a firm can sell any amount at the existing price
Explanation: Firm’s demand curve is a horizontal straight line under perfect competition. Demand curve of the firm is perfectly elastic. It means that the firm can sell any amount of the commodity at the prevailing price. The horizontal straight line shows that the firm is to accept the price as determined by the forces of market supply and market demand; it can sell whatever amount it wishes to sell at this price. - (c) Yes
Explanation: The MR curve slopes downward but at twice the rate of AR. When TR is maximum MR is zero. Any increase in output beyond the point where MR=0 leads to a negative MR. - (d) Imputed costs
Explanation: It is the cost of self supplied factors. - (a) Perfect competition
Explanation: As a firm under this competition is a price taker, i.e , which is fixed by the industry (demand and supply forces) . Therefore each firm is a price taker and faces a perfectly elastic demand curve. - There are three reasons which give rise to an economic problem.:
- Wants of people are unlimited – It is due to unending circle of wants. After the satisfaction of one wants, another want arises.
- Resources are limited – Problem of allocation of resources arises because resources are not enough to satisfy wants of every individual.
- Resources have alternative uses – Scarce resources have alternative uses. When an individual chooses to use a given resources for something, he/she is unable to use that resources for anything else.
OR
The central problems of a production deal with the production of necessary commodities using scarce means of resources. It includes problems that deal with the production of goods in an economy where it is decided that:
What to produce? Consumer goods or capital goods?
How to produce? Using labour intensive technique or capital intensive technique
For whom to produce? Rich people or poor people? - The following three conditions must hold if a profit-maximizing firm produces a positive level of output (say equilibrium output Q*) in a competitive market:
- MR must be equal to MC at Q*.
- MC should be upward sloping or rising at Q*.
- In short-run – Price must be greater than or equal to AVC. i.e. P {tex}\geq{/tex} AVC at Q*.
In the long run – Price must be greater than or equal to Long-run average cost.
- One should distinguish between ‘value-in-use’ and ‘market value’ of a commodity. Water has high ‘value-in-use’, of course. But its market value (price) is low (compared with diamonds) because it is available in plenty. In terms of its market supply, water is scarce, but not as scarce as diamonds.
Therefore, market price of water is much lower than of the diamonds. Imagine a situation when you are in a desert and you are dying to quench your thirst. You are then ready to pay any amount for a glass of water. - Producer’s equilibrium: It is a situation of profit maximisation.
- For attaining producer’s equilibrium, following two conditions are required to be satisfied :
- Marginal Revenue (MR) = Marginal Cost (MC), and
- Marginal Cost must be rising beyond the point of equilibrium.
- Following schedule explains the producer’s equilibrium:
Marginal Revenue and Cost Schedule Output Marginal Revenue (MR) (in Rs) Marginal Cost (MC) (in Rs) 1 12 15 2 12 12 3 12 10 4 12 9 5 12 8 6 12 7 7 12 8 8 12 9 9 12 10 10 12 12 (Producer’s equilibrium) 11 12 15 At 2nd level of output, Marginal Revenue and Margimal Cost are equal but at 3rd level of output Marginal Revenue > Marginal Cost (12 > 10). Hence, firms will continue to expand production as their profits are not yet maximised. Producer will be in equilibrium at 10th level of output because beyond this level, Marginal Cost exceeds Marginal Revenue.
OR
- At this point, where MR>MC both the equilibrium conditions (i) MR = MC (ii) MC should cut MR from below are not satisfied.
- The firm will try to be in equilibrium by expanding the output to the level, where MC = MR.
- The producer will get either maximum Profits or sets minimum losses at the Point of equality between MR and MC.
- At this point of equality of MR and MC, if the second condition of equilibrium is also satisfied only then the producer will be in equilibrium because MR = MC or equality between MR and MC is a necessary but not a sufficient condition of equilibrium.
- The producer will be in equilibrium only when the following two conditions are satisfied simultaneously.
- MR = MC
- MC should cut MR from below.
- Demand of a commodity is inversely related to its price can be explained with the help of the table given below:
Demand schedulePrice (Rs) Quantity demanded (units) 10 50 8 60 6 70 4 80 2 90 As per The Law of Diminishing Marginal Utility, a consumer consumes successive units of an identical commodity, then Marginal Utility derived from an additional unit goes on declining. This implies that as a consumer’s utility is declining, then he would not be willing to buy an additional unit at the same price. But, if the good is offered to him at a reduced price, then this will induce him to increase his consumption. So, we can say that price and demand of a commodity are inversely related due to Law of Diminishing Marginal Utility and consumer buys a good upto the point at which MU = Price.
- Law of variable proportion states the impact of change in units of a variable factor on the physical output. When more and more units of a variable factor are combined with a fixed factor then total product increases at increasing rate in the beginning, then increases at decreasing rate and finally it starts falling.
Phase I : TP increases at an increasing rate.
Phase II : TP increases at diminishing rate.
Phase III : TP falls.
Behaviour of MP
Phase I: MP increases and becomes maximum.
Phase II: MP decreases and becomes zero.
Phase III: MP becomes negativeMachine Unit of Labour TPP (Unit) MPP(Unit) 1 1 3 3 1 2 7 4 1 3 12 5 1 4 16 4 1 5 19 3 1 6 21 2 1 7 22 1 1 8 22 0 1 9 21 -1
First Phase : TPP increases with increasing rate upto A point. MPP also increase and becomes maximum at point C.
Second Phase : TPP increases with diminishing rate and it is maximum at point B. MPP start to decline and becomes zero at D point.
Third Phase : TPP starts to decline and MPP becomes negative.- Important instruction for giving the answer of above question.
- Do not use diagram for the explanation of this question if it is instructed to use schedule and do not use schedule if the explanation of this question asked with the help of diagram.
- Do not explain the behaviour of marginal product with the help of schedule and diagram. If there is instruction to explain only the behaviour of total product.
- Do not explain the behaviour of total product with help of schedule and diagram if there is instruction to explain only the behaviour of marginal product.
- Answer the following questions
- Percentage Change in Demand {tex}= \frac { \text { Change in Demand } } { \text { Old Demand } } \times 100{/tex}
{tex}= \frac { 220 – 200 } { 200 } \times 100 = 10 \%{/tex}
Given,Percentage change in Price = 10%
Elasticity of Demand (Ed)
{tex}= ( – ) \frac { \text { Percentage change in quantity demanded } } { \text { Percentage change in price } }{/tex}
{tex}= ( – ) \frac { 10 } { 10 } = ( – 1 ){/tex}
{tex}\therefore{/tex}Ed = (-1) - Price elasticity of demand is an economic measure of the change in the quantity demanded or purchased of a product in relation to its price change.
{tex}\mathrm{E}_{\mathrm{d}}=\frac{\Delta \mathrm{Q}}{\mathrm{Q}} \times \frac{\mathrm{P}}{\Delta \mathrm{P}}{/tex}
{tex}\Delta Q{/tex}= 18 -18 = 0
{tex}\Delta P{/tex}= 10 – 9 = 1
P = 10
Q = 18
By substituting the values we get:
{tex}\mathrm{E}_{\mathrm{d}}=\frac{0}{18} \times \frac{10}{1}=\frac{0}{18}=0{/tex}
Perfectly inelastic demand.
- Percentage Change in Demand {tex}= \frac { \text { Change in Demand } } { \text { Old Demand } } \times 100{/tex}
