An economy does not always on a ppc . when an economy produces on ppc it mean there is no unemployment and all the resources are fully and being used efficiently but practically these 2 conditions may not apply . if there is unemployment or inefficent use of resources an ecnmy will opreate inside the ppc therefor the above given statement is refuted .

The want satisfying power of a commodity is known as:
  • a)
    Utility
  • b)
    Consumption
  • c)
    Supply
  • d)
    Demand
Correct answer is option 'A'. Can you explain this answer?

Aryan Khanna answered
The want satisfying power of a commodity is called utility. It is a quality possessed by a commodity or service to satisfy human wants. Utility can also be defined as value-in-use of a commodity because the satisfaction which we get from the consumption of a commodity is its value-in-use.

According to the law of diminishing marginal utility, _________?
  • a)
    Additional consumption always yields extra utility
  • b)
    Additional consumption leads to lower average total utility
  • c)
    Additional consumption always yields negative utility
  • d)
    After a point any addition in the consumption causes a reduction in total utility.
Correct answer is option 'D'. Can you explain this answer?

Priya Patel answered
According to the Law of Diminishing Marginal Utility, marginal utility of a good diminishes as an individual consumes more units of a good. In other words, as a consumer takes more units of a good, the extra utility or satisfaction that he derives from an extra unit of the good goes on falling.
It should be carefully noted that is the marginal utility and not the total utility than declines with the increase in the consumption of a good. The law of diminishing marginal utility means that the total utility increases but at a decreasing rate.

Can you explain the answer of this question below:

Indifference curve represents?

  • A:

    Four commodities

  • B:

    Less than two commodities

  • C:

    Only two commodities

  • D:

    More than two commodities

The answer is C.

Alok Mehta answered
An indifference curve is a graph showing combination of two goods that give the consumer equal satisfaction and utility. Each point on an indifference curve indicates that a consumer is indifferent between the two and all points give him the same utility.

Which of the following curve has a negative slope and cannot interest each other?
  • a)
    Isoquants
  • b)
    Demand and supply curves
  • c)
    Indifference curves
  • d)
    None of above
Correct answer is option 'C'. Can you explain this answer?

Vikas Kapoor answered
An indifference curve connects points on a graph representing different quantities of two goods, points between which a consumer is indifferent. Along the curve, the consumer has no preference for either combination of goods because both goods provide the same level of utility.
Each indifference curve is convex to the origin, and no two indifference curves ever intersect.

The coefficient of price elasticity of demand is always
  • a)
    Zero
  • b)
    Undefined
  • c)
    Positive
  • d)
    Negative
Correct answer is option 'D'. Can you explain this answer?

Devansh Goyal answered
Explanation:

The coefficient of price elasticity of demand is a measure of the responsiveness of the quantity demanded of a good or service to changes in its price. It is calculated as the percentage change in quantity demanded divided by the percentage change in price.

The coefficient of price elasticity of demand can take on different values depending on the degree of responsiveness of quantity demanded to price changes. However, it is always negative because of the inverse relationship between price and quantity demanded.

Here are some possible values of the coefficient of price elasticity of demand and what they indicate:

- Elastic demand (|PED| > 1): A small percentage change in price leads to a relatively larger percentage change in quantity demanded. Consumers are very responsive to price changes, and the total revenue of the seller decreases when the price is increased.
- Inelastic demand (|PED| < 1):="" a="" large="" percentage="" change="" in="" price="" leads="" to="" a="" relatively="" small="" percentage="" change="" in="" quantity="" demanded.="" consumers="" are="" not="" very="" responsive="" to="" price="" changes,="" and="" the="" total="" revenue="" of="" the="" seller="" increases="" when="" the="" price="" is="">
- Unit elastic demand (|PED| = 1): A percentage change in price leads to an equal percentage change in quantity demanded. The total revenue of the seller remains constant when the price is changed.

Conclusion:

In conclusion, the coefficient of price elasticity of demand is always negative because of the inverse relationship between price and quantity demanded. The value of this coefficient can vary depending on the degree of responsiveness of quantity demanded to price changes.

Opportunity cost is the
  • a)
    Next best alternative sacrificed
  • b)
    Next best alternative chosen
  • c)
    Next best alternative available
  • d)
    Next best alternative produced
Correct answer is option 'A'. Can you explain this answer?

Knowledge Hub answered
“Opportunity cost” of a resource, means the value of the next-highest-valued alternative use of that resource.
E.g. you spend time and money going to a movie, you cannot spend that time at home playing video games, and you cannot spend the money on something else. If your next-best alternative to seeing the movie is playing video games at home, then the opportunity cost of seeing the movie is the money spent plus the pleasure you forgo by not playing videos game at home.

Utility is measured in terms of?
  • a)
    Centimeter
  • b)
    Seconds
  • c)
    Gram
  • d)
    Utils
Correct answer is option 'D'. Can you explain this answer?

Alok Mehta answered
It can be seen that utility is measured in numbers that are purely cardinal, rather than ordinal. The numbers used to measure utility (often in a unit called the "util") is useful only for comparison.

The firm and the industry are one and the same in:
  • a)
    Monopolistic competition
  • b)
    Monopoly
  • c)
    Duopoly
  • d)
    Oligopoly
Correct answer is option 'B'. Can you explain this answer?

Priya Patel answered
A type of market structure, where the firm has absolute power to produce and sell a product or service having no close substitutes. In simple terms, monopolised market is one where there is a single seller, selling a product with no near substitutes to a large number of buyers. As the firm and industry are one and the same thing in the monopoly market, so it is a single-firm industry. There is zero or negative cross elasticity of demand for a monopoly product. Monopoly can be found in public utility services such as telephone, electricity and so on.

 _____________ is defined as the difference between what the consumer is willing to pay for a product and what he actually pays?
  • a)
    Consumer surplus
  • b)
    Price gap
  • c)
    Consumer burden
  • d)
    Optimum price
Correct answer is option 'A'. Can you explain this answer?

Devansh Goyal answered
The consumer surplus is the difference between the highest price a consumer is willing to pay and the actual market price of the good. The producer surplus is the difference between the market price and the lowest price a producer would be willing to accept. For producers, a surplus can be thought of as profit, because producers usually don't want to produce at a loss. The two together create an economic surplus.

Which of the following utility approach is based on the theory of Alfred Marshall?
  • a)
    Independent variable approach
  • b)
    Cardinal utility approach
  • c)
    Ordinal utility approach
  • d)
    None of these
Correct answer is option 'B'. Can you explain this answer?

The Cardinal Utility approach is propounded by neo-classical economists, who believe that utility is measurable, and the customer can express his satisfaction in cardinal or quantitative numbers, such as 1,2,3, and so on.  Here, one Util is equivalent to one rupee and the utility of money remains constant.

The concept of marginal utility was developed by?

    Alfred Marshall
  • c)
    Hicks & Allen
  • d)
    Robbins
Correct answer is option 'B'. Can you explain this answer?

Aryan Khanna answered
The concept of marginal utility grew out of attempts by economists to explain the determination of price. The term “marginal utility”, credited to the Austrian economist Friedrich von Wieser by Alfred Marshall, was a translation of Wieser's term “Grenznutzen” (border-use).

  • a)
    MR is maximum
  • b)
    MR<0
  • c)
    MR>0
  • d)
    MR is zero
Correct answer is option 'D'. Can you explain this answer?

Aryan Khanna answered
Marginal revenue means additional revenue generate/received from the sale of additional unit of output.In imperfect (monopoly) when TR increases MR decreases , when TR become maximum MR reaches to zero.

  • a)
    When marginal utility remains constant
  • b)
    When marginal utility is increasing
  • c)
     When marginal utility is negative
  • d)
    When marginal utility is negative
Correct answer is option 'D'. Can you explain this answer?

Kiran Mehta answered
The law of diminishing marginal utility is a law of economics stating that as a person in creases consumption of a products while keeping consumption of other product costant , there is a decline in the marginal utility that persob derives from consuming each additional unit of product.

  • a)
    Buyer’s surplus
  • b)
    Elasticity of demand
  • c)
    Differential surplus
  • d)
     Indifference surplus
Correct answer is option 'A'. Can you explain this answer?

Arun Khanna answered
Consumer surplus is defined as the difference between the total amount that consumers are willing and able to pay for a good or service (indicated by the demand curve) and the total amount that they actually do pay (i.e. the market price) it is also known as buyer 's surplus.

The slope of price line throughout its length?
  • a)
    Remains the same
  • b)
    Is equal on the other side of the mid points
  • c)
    Differs from point to point
  • d)
    None of above
Correct answer is option 'A'. Can you explain this answer?

This is because in perfect competition , price line is a straight line. And the ratio (∆TR/∆Q )That is change in total revenue and change in output is constant.{MR=AR}So slope of a straight line is always constant.

Price discrimination can take place only in
  • a)
    Perfect competition
  • b)
    Oligopoly
  • c)
    Monopolistic competition

Correct answer is option 'D'. Can you explain this answer?

Pooja Kumari answered
Monopoly.... ... A discriminating monopoly is a single entity that charges different prices—typically, those that are not associated with the cost to provide the product or service—for its products or services for different consumers. Non-discriminating monopolies, on the other hand, do not engage in such a practice

  • c)
    Addition to the total revenue on the sale of an additional unit of Output
  • d)
    Additional cost involved in production
Correct answer is option 'C'. Can you explain this answer?

Simran Mishra answered
**Marginal Revenue: Addition to the total revenue on the sale of an additional unit of Output**

Marginal revenue is a concept used in economics to describe the additional revenue generated from the sale of one additional unit of output or product. It is the change in total revenue that occurs as a result of producing and selling one more unit of a product.

**Explanation:**

Marginal revenue is calculated by dividing the change in total revenue by the change in the quantity of output sold. It represents the increase in revenue that a firm earns when it sells one more unit of output.

To understand this concept, let's consider an example of a company that sells smartphones. Suppose the company sells its smartphones for $500 each, and it sells 1000 units in a month, resulting in a total revenue of $500,000. Now, if the company decides to produce and sell one more smartphone, it would have to adjust its price to attract buyers. Let's assume the company reduces the price to $400 for the additional unit.

In this case, the marginal revenue for the additional unit would be $400 because that is the amount of revenue generated from the sale of that unit. The total revenue after selling 1001 units would be $500,000 + $400 = $500,400. Therefore, the marginal revenue for the additional unit is $400.

It is important to note that marginal revenue can vary depending on the market conditions, demand for the product, and the pricing strategies employed by the firm. In some cases, marginal revenue may be positive, indicating an increase in revenue from selling an additional unit. However, in certain situations, such as when the market is highly competitive, marginal revenue may be negative, indicating a decrease in revenue from selling an additional unit.

Overall, marginal revenue is a crucial concept for businesses as it helps them determine the optimal level of production and pricing strategies to maximize their profits. By understanding the change in revenue associated with each additional unit of output, firms can make informed decisions regarding their production and pricing policies.

Which of the following utility approach suggests that utility is a measurable and quantifiable entity?
  • a)
    Ordinal approach
  • b)
    Cardinal approach
  • c)
    Both cardinal & ordinal
  • d)
    None of these
Correct answer is option 'B'. Can you explain this answer?

Jayant Mishra answered
Cardinal Utility
Definition: The Cardinal Utility approach is propounded by neo-classical economists, who believe that utility is measurable, and the customer can express his satisfaction in cardinal or quantitative numbers, such as 1,2,3, and so on.The neo-classical economist developed the theory of consumption based on the assumption that utility is measurable and can be expressed cardinally. And to do so, they have introduced a hypothetical unit called as “Utils” meaning the units of utility. Here, one Util is equivalent to one rupee and the utility of money remains constant.

Explicit costs are paid to
  • a)
    External owners of factors
  • b)
    The tax authorities
  • c)
    Internal owners of factors
  • d)
    The government
Correct answer is option 'A'. Can you explain this answer?

Poonam Reddy answered
Total cost is what the firm pays for producing and selling its products. Explicit costs are normal business expenses that are easy to track and appear in the general ledger. Explicit costs are the only costs necessary to calculate a profit, as they clearly affect a company's profits. Wages that a firm pays its employees or rent that a firm pays for its office are explicit costs.

    Market price fall below the equilibrium price
  • b)
    Market price rise higher than the equilibrium price
  • c)
    Market price remains the same
  • d)
    none

  • a)
    Market price remains the same
  • b)
    Market price rise
  • c)
    Market price falls below the equilibrium price
  • d)
    Market price fall
Correct answer is option 'D'. Can you explain this answer?

The situation of deficient demand arises when planned aggregate expenditure falls short of aggregate supply at the full employment level.

A rise in the price of the complementary good leads to
  • a)
    Shift of the demand curve of the given good only
  • b)
    Expansion of the supply curve of the given good only
  • c)
    Contraction of the demand for the given good
  • d)
    Shift of the demand and supply curves of the given good
Correct answer is option 'C'. Can you explain this answer?

Nandini Iyer answered
Complementary good or complement is a good with a negative cross elasticity of demand, in contrast to a substitute good. This means a good's demand is increased when the price of another good is decreased. ... When two goods are complements, they experience joint demand.

A complementary good is a good whose use is related to the use of an associated or paired good. Two goods (A and B) are complementary if using more of good A requires the use of more of good B. For example, the demand for one good (printers) generates demand for the other (ink cartridges).

Which of the following is not true?
  • a)
    Indifference curves cannot intersect each other
  • b)
    Two indifference curve can be tangent to each other
  • c)
    Indifference curves are convex to the origin
  • d)
    Indifference curves slopes downward to the right
Correct answer is option 'B'. Can you explain this answer?

Aryan Khanna answered
Each indifference curve is convex to the origin, and no two indifference curves ever intersect. Consumers are always assumed to be more satisfied when achieving bundles of goods on higher indifference curves. If a consumer's income increases, the curve will move higher up on a graph because the consumer can now afford more of each type of good.

This a MCQ (Multiple Choice Question) based practice test of Chapter 2 - Theory of Consumer Behaviour  of Economics of Class XII (12) for the quick revision/preparation of School Board examinations
Q  Which of the following statements regarding utility is not true?
  • a)
    It helps consumers to make choices.
  • b)
    Utility is always measurable.
  • c)
    It is a satisfying power of a commodity.
  • d)
    It is purely a subjective entity.
Correct answer is option 'B'. Can you explain this answer?

Utility is an economic term referring to the total satisfaction received from consuming a good or service. The economic utility of a good or service is important to understand because it will directly influence the demand, and therefore price, of that good or service. A consumer's utility is hard to measure, however, but it can be determined indirectly with consumer behavior theories, which assume that consumers will strive to maximize their utility.

The fixed cost curve is a horizontal straight line to the X axis because
  • a)
    It is impossible to change
  • b)
    IT remains same even if fixed factors change
  • c)
    It remains constant in the long run
  • d)
    It remains constant in the short run
Correct answer is option 'D'. Can you explain this answer?

Rajat Patel answered
We know, in the short run, there are some factors which are fixed, while others are variable. Similarly, short run costs are also divided into two kinds of costs:(i) Fixed Cost
The sum total of fixed cost and variable cost is equal to total cost. Let us discuss the short run costs in detail.Units of output are measured along the X-axis and fixed costs along the Y-axis. ... The curve makes an intercept on the Y-axis, which is equal to the fixed cost of Rs. 12. TFC curve is a horizontal straight line parallel to the X-axis because TFC remains same at all levels of output,It remains constant in the short run

_____________ is the addition to total utility by the consumption of one additional unit of the commodity?
  • a)
    Average utility
  • b)
    Ordinal utility
  • c)
    Marginal utility
  • d)
    Total utility
Correct answer is 'C'. Can you explain this answer?

Priya Patel answered
The Marginal Utility refers to the additional benefit (utility) a consumer derives from the consumption of one additional unit of good or service.
In other words, marginal utility is the addition to the total utility resulting from the consumption of one additional unit of the commodity. Thus, it can be measured as the change in the total utility obtained from the consumption of an additional unit.
