A budget constraint line is a result of?
  • a)
    Market price of commodity X
  • b)
    Market price of commodity Y
  • c)
    Income of the consumer
  • d)
    All of above
Correct answer is option 'A'. Can you explain this answer?

Explanation:

A budget constraint line is a graphical representation of the various combinations of two goods that a consumer can afford, given his/her income and the prices of the goods. It is also called a budget line or a price line.

The budget constraint line is a result of the market price of commodity X, which is one of the two goods that the consumer is considering purchasing. The market price of commodity Y is also a factor in determining the slope of the budget constraint line, but it is not the result of the line.

The income of the consumer is also an important factor in determining the position of the budget constraint line on the graph. The higher the income, the further out the line will be from the origin, indicating that the consumer can afford to purchase more of both goods.

However, the income of the consumer is not the result of the budget constraint line. It is simply a factor that is taken into account when drawing the line.

In summary, the budget constraint line is a result of the market price of commodity X, and to a lesser extent, the market price of commodity Y. The income of the consumer is a factor that is taken into account when drawing the line, but it is not the result of the line itself.

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.

Indifference curve represents?

  • A:

    Four commodities

  • B:

    Less 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.

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.

 _____________ 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?
  • a)
    Paul Samuelson
  • b)
    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).

At what point does total utility starts diminishing?
  • 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.

Consumer’s surplus is also known as?
  • 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.

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.

_____________ 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.

____________ shows various combinations of two goods that give same amount of satisfaction to the consumer?
  • a)
    Isocost curve
  • b)
    Marginal utility curve
  • c)
    Indifference curve
  • d)
    Isoquant
Correct answer is option 'C'. Can you explain this answer?

Indifference curve is defined as the locus of points on the graph each representing a different combination of two substitute goods, which yield the same utility or level of satisfaction to a consumer. The combinations of goods give equal satisfaction to a consumer.

Therefore, a consumer is indifferent between any two combinations of two goods when it comes to making a choice between them. When these combinations are plotted on the graph, the resulting curve is called indifference curve. This curve is also called as iso-utility curve or equal utility curve.

MU1 + MU2 + ……..MUn represents?
  • a)
    Total marginal utility
  • b)
    Total utility of a commodity
  • c)
    Total average utility
  • d)
    None of the above
Correct answer is option 'B'. Can you explain this answer?

Aryan Khanna answered
Utility, in ordinary sense, means usefulness. But, in economics, it means want-satisfying power of a commodity or service — the power to satisfy a human want. Utility is addable. One can add utility obtained from each unit of a commodity to get total utility obtained from the entire stock. In other words, by adding marginal utility from successive units, we obtain total utility of the stock.

An indifference curve indicates, ceteris paribus?
  • a)
    Combinations of goods which yield to a producer different levels of satisfaction
  • b)
    Combinations of goods which yield to a consumer equal degrees of satisfaction
  • c)
    Combinations of goods which yield to a consumer different levels of satisfaction
  • d)
    A consumer’s preference for any two goods
Correct answer is option 'B'. Can you explain this answer?

Poonam Reddy answered
In economics, an indifference curve connects points on a graph representing different quantities of two goods, points between which a consumer is indifferent. ... In other words, an indifference curve is the locus of various points showing different combinations of two goods providing equal utility to the consumer.

According to Marshall, the law of diminishing marginal utility applies on ___________?
  • a)
    All commodities except money
  • b)
    Bank money
  • c)
    Money in the same manner as it applies on the commodity
  • d)
    Cash but not on bank money
Correct answer is option 'A'. Can you explain this answer?

Naina Sharma answered
The law of diminishing marginal utility states that with the consumption of every successive unit of commodity yields marginal utility with a diminishing rate. However, there are certain things on which the law of diminishing marginal utility does not apply. 

The total utility divided by the number of units consumed is known as?
  • a)
    Average utility
  • b)
    Total utility 
  • c)
    Marginal utility
  • d)
    None of above
Correct answer is option 'A'. Can you explain this answer?

Ranvir Mishra answered
Average utility because(iii) Average Utility:
Average Utility is that utility in which the total unit of consumption of goods is divided by number of Total Units. The Quotient is known as Average Utility.

Total utility is maximum when?
  • a)
    Marginal utility is zero.
  • b)
    Average utility is equal to zero
  • c)
    Average utility is maximum
  • d)
    Marginal utility is maximum
Correct answer is option 'A'. Can you explain this answer?

Akshara Dey answered
Explanation:

Total utility refers to the total satisfaction or happiness that a consumer derives from the consumption of a good or service. The law of diminishing marginal utility states that as a consumer consumes more and more units of a good or service, the additional satisfaction derived from each additional unit decreases. Therefore, the total utility increases at a decreasing rate.

When is Total Utility Maximum?

Total utility is maximum when a consumer consumes a certain amount of a good or service where the marginal utility is zero. This is because when the marginal utility of a good or service is zero, the total utility is at its maximum possible level.

Why is Marginal Utility Zero?

Marginal utility is zero when the consumer has consumed the optimal level of a good or service. At this point, the additional satisfaction derived from consuming an additional unit of the good or service is zero. Therefore, the total utility is at its maximum level.

Example:

For example, if a consumer is hungry and eats an apple, the first apple will give the consumer a high level of satisfaction. However, as the consumer continues to eat more apples, the marginal utility of each additional apple will decrease. Eventually, the consumer will reach a point where the marginal utility of the next apple is zero, and the total utility is at its maximum level.

Therefore, the correct answer is option 'A' - Total utility is maximum when the marginal utility is zero.

In case of relatively more elastic curve, demand curve is:
  • a)
    Horizontal
  • b)
    Vertical
  • c)
    Steeper
  • d)
    Flatter
  • e)
    In case of relatively more elastic, demand curve is:(i) Horizontal(ii) Vertical(iii) Steeper(iv) Flatter
Correct answer is option 'D'. Can you explain this answer?

Gauri Chavan answered
Explanation:

Elasticity refers to the degree of responsiveness of demand to changes in price. When demand is relatively more elastic, it means that a small change in price leads to a larger change in quantity demanded. This results in a flatter demand curve.

Demand curve is a graphical representation of the relationship between the price of a good or service and the quantity demanded by consumers. The slope of the demand curve represents the degree of responsiveness of demand to changes in price.

When demand is relatively more elastic, the demand curve is flatter. This means that a small change in price leads to a larger change in quantity demanded. In other words, consumers are more responsive to changes in price, and are likely to buy more of the good or service when the price is lowered.

Option D is the correct answer because a flatter demand curve indicates that demand is relatively more elastic. A horizontal demand curve would indicate perfect elasticity, while a vertical demand curve would indicate perfect inelasticity.

In summary, when demand is relatively more elastic, the demand curve is flatter, indicating that a small change in price leads to a larger change in quantity demanded.

Consumer’s equilibrium means?
  • a)
    The point from where the consumer starts his consumption
  • b)
    The position which the consumer cannot attain because his income is low
  • c)
    The position of rest or maximum satisfaction with given income and prices
  • d)
    The position of frequent movement in all directions
Correct answer is option 'C'. Can you explain this answer?

Maitri Sharma answered
A consumer is an individual or household that purchases goods and services for their personal use or consumption. They play a crucial role in the economy by driving demand and influencing market trends. Consumers make choices based on their needs, preferences, and budget constraints. They can be categorized into various types, such as impulse buyers, price-conscious consumers, brand loyalists, or environmentally conscious consumers. Consumer behavior is influenced by factors such as advertising, social media, peer recommendations, and personal experiences. Companies conduct market research to understand consumer needs and develop products and marketing strategies to attract and retain them.
