Understanding Price Elasticity of Demand
Price elasticity of demand measures how much the quantity demanded of a good responds to a change in its price. It is calculated using the formula:
Price Elasticity of Demand (PED) = (Percentage Change in Quantity Demanded) / (Percentage Change in Price)
Given that the price elasticity is -2, we can interpret this as follows:
- A 1% decrease in price leads to a 2% increase in quantity demanded.
Initial Price and Quantity Changes
- Initial Price: Rs. 10 per unit
- Price Change: Rs. 2 drop, leading to a new price of Rs. 8 per unit
- Quantity Demand Increase: 10 units
Calculating the Initial Quantity Demanded
1. Calculating Percentage Change in Price:
- Initial Price = Rs. 10
- New Price = Rs. 8
- Price Change = Rs. 10 - Rs. 8 = Rs. 2
Percentage Change in Price = (Price Change / Initial Price) * 100 = (2 / 10) * 100 = 20%
2. Using Price Elasticity:
Since PED = -2 and represents a 20% change in price, we can find the percentage change in quantity demanded:
-2 = (Percentage Change in Quantity Demanded) / (-20)
Thus, the Percentage Change in Quantity Demanded = 2 * 20 = 40%
3. Calculating Quantity Demanded:
If the quantity demanded increases by 40%, we can set up the following:
- Increase in Quantity = 10 units
- Let Initial Quantity Demanded = Q
Therefore, 40% of Q = 10
Q = 10 / 0.4 = 25 units
Conclusion
- Initial Quantity Demanded: 25 units
- Final Quantity Demanded after Price Drop: 25 + 10 = 35 units
Thus, the quantity demanded at the new price of Rs. 8 per unit is 35 units.
