## Chapter – 2: Elasticity of Demand – III (Proofs)

Q.3. (i) Prove that the elasticity of a downward sloping straight-line demand curve varies from infinity (left ( infty right )) at the price- axis to zero at the quantity-axis.  (ii) Comparing two straight line demand curves of the same slope, the one farther from the origin is less elastic at each price than the …

## Chapter – 1: Concept of Demand – III (Movement & Shift)

Q3. Distinguish between change in quantity demanded and change in demand. or Differentiate between movement along a demand curve and shift in a demand curve. Ans. Change in quantity demanded means change in demand that takes place due to a change in price. Movement along a demand curve refers to a change in quantity demanded …

## Chapter – 1: Concept of Demand – II

Q.2. Why does a demand curve usually slope downward to the right? Are there any exceptions to it? Ans. Usually, a demand curve slopes downward to the right. This means the slope of the demand curve is negative. A downward-sloping demand curve shows an inverse relationship between the price and the quantity demanded. In the …
