Question
Given the demand schedule:
| Price (Rs.) | 25 | 20 | 15 | 10 | 5 |
|---|---|---|---|---|---|
| Quantity Demanded | 50 | 100 | 150 | 200 | 250 |
a) Calculate the price elasticity of demand from point Rs. 20 to Rs. 15 using the point method.
b) Compute the arc elasticity of demand between points Rs. 15 and Rs. 10. [5+0+0]
Price (Rs.) 25 20 15 10 5 ------------------ Quantity Demanded 50 100 150 200 250 --- Formula (Point Method): $$Ed = \frac{\Delta Q}{\Delta P} \times \frac{P}{Q}$$ Data: - Initial point: $P = 20$, $Q = 100$ - New point: $P = 15$, $Q = 150$ Working: $$\Delta Q = 150 - 100 = 50$$ $$\Delta P = 15 - ...
