Assertion and Reason Based

Q1: Assertion: Elasticity of demand measures the responsiveness of demand due to changes in price.
Reason: Price elasticity of demand (ED) measures the change in price due to a change in demand.
(a) Both assertion and reason are correct, and the reason is the correct explanation of the assertion.
(b) Both assertion and reason are correct, but the reason is not the correct explanation of the assertion.
(c) Assertion is correct, but the reason is incorrect.
(d) Assertion is incorrect, but the reason is correct.

Q2: Assertion: Perfectly elastic demand (ED = ∞) occurs when demand changes infinitely without any change in price.
Reason: It exists under perfect competition.
(a) Both assertion and reason are correct, and the reason is the correct explanation of the assertion.
(b) Both assertion and reason are correct, but the reason is not the correct explanation of the assertion.
(c) Assertion is correct, but the reason is incorrect.
(d) Assertion is incorrect, but the reason is correct.

Q3: Assertion: Availability of close substitutes makes demand more elastic.
Reason: Close substitutes provide consumers with alternatives, making them more responsive to price changes.
(a) Both assertion and reason are correct, and the reason is the correct explanation of the assertion.
(b) Both assertion and reason are correct, but the reason is not the correct explanation of the assertion.
(c) Assertion is correct, but the reason is incorrect.
(d) Assertion is incorrect, but the reason is correct.

Q4: Assertion: In the total expenditure method, when elasticity is greater than 1, it indicates elastic demand.
Reason: Elastic demand means that consumers respond significantly to price changes.
(a) Both assertion and reason are correct, and the reason is the correct explanation of the assertion.
(b) Both assertion and reason are correct, but the reason is not the correct explanation of the assertion.
(c) Assertion is correct, but the reason is incorrect.
(d) Assertion is incorrect, but the reason is correct.

Q5: Assertion: When price level is low, articles tend to have inelastic demand.
Reason: Inelastic demand means that small price changes do not significantly impact consumer budgets.
(a) Both assertion and reason are correct, and the reason is the correct explanation of the assertion.
(b) Both assertion and reason are correct, but the reason is not the correct explanation of the assertion.
(c) Assertion is correct, but the reason is incorrect.
(d) Assertion is incorrect, but the reason is correct.

FAQs on Worksheet: Theory of Consumer Behaviour - 2 - Economics Class 11 - Commerce

1. What is the theory of consumer behaviour?
Ans. The theory of consumer behaviour is a concept that explains how individuals make decisions regarding the selection and consumption of goods and services. It focuses on understanding the factors that influence consumer choices, such as preferences, income, prices, and market conditions.
2. What are the key assumptions of the theory of consumer behaviour?
Ans. The theory of consumer behaviour is based on several key assumptions. Firstly, consumers aim to maximize their utility or satisfaction. Secondly, consumers have rational preferences and make consistent choices. Thirdly, consumers have limited income and face budget constraints. Lastly, consumers have complete information about the available choices and their characteristics.
3. How does the theory of consumer behaviour explain consumer demand?
Ans. The theory of consumer behaviour explains consumer demand through the concept of utility maximization. According to this theory, consumers allocate their limited income to purchase goods and services that provide them with the highest level of satisfaction or utility. This allocation is influenced by the prices of goods and services, the consumer's income level, and the consumer's preferences.
4. What are the different types of utility in the theory of consumer behaviour?
Ans. The theory of consumer behaviour recognizes two types of utility: total utility and marginal utility. Total utility refers to the overall satisfaction a consumer derives from consuming a certain quantity of a good or service. Marginal utility, on the other hand, refers to the additional satisfaction gained from consuming an additional unit of a good or service.
5. How do income and substitution effects play a role in the theory of consumer behaviour?
Ans. Income and substitution effects are important concepts in the theory of consumer behaviour. The income effect refers to the change in consumer demand due to a change in income level. When income increases, consumers can afford to purchase more goods and services, leading to an increase in demand. The substitution effect, on the other hand, refers to the change in consumer demand due to a change in the relative prices of goods and services. When the price of a good increases, consumers may switch to cheaper alternatives, leading to a decrease in demand for the more expensive good.
