Assertion and Reasoning type of question:

Assertion (A): Elasticity of demand explains that one variable is influenced by another variable.

Reasoning (R): The concept of elasticity of demand indicates the effect of price and changes in other factors on demand.

• (A) is true, but (R) is false

• (A) is false, but (R) is true

• Both (A) and (R) are true and (R) is the correct explanation of (A)

• Both (A) and (R) are true and (R) is not the correct explanation of (A)

Exercise | Q 4. (2) | Page 35

Assertion and Reasoning type of question:

Assertion (A): A change in quantity demanded of one commodity due to a change in the price of other commodity is cross elasticity

Reasoning (R): Changes in consumer income leads to a change in the quantity demanded.

• (A) is true, but (R) is false

• (A) is false, but (R) is true

• Both (A) and (R) are true and (R) is the correct explanation of (A)

• Both (A) and (R) are true and (R) is not the correct explanation of (A)
