Question : If the price elasticity of demand for a good is 1.2, then a 10% decrease in price will result in a:
Option 1: 1.2% increase in quantity demanded.
Option 2: 12% increase in quantity demanded.
Option 3: 1.2% decrease in quantity demanded.
Option 4: 12% decrease in quantity demanded.
Correct Answer: 12% increase in quantity demanded.
Solution : The correct answer is (b) 12% increase in quantity demanded.
A price elasticity of demand value of 1.2 indicates elastic demand. This means that a 1% change in price will result in a 1.2% change in quantity demanded. Therefore, a 10% decrease in price will lead to a proportionately larger increase in quantity demanded, which is 12% based on the elasticity value of 1.2.
When demand is elastic, changes in price have a relatively larger impact on quantity demanded. Hence, a 10% decrease in price will result in a 12% increase in quantity demanded.
Question : If the price elasticity of demand for a good is -1.5, then a 10% increase in price will result in a:
Option 1: 10% decrease in quantity demanded.
Option 2: 15% decrease in quantity demanded.
Option 3: 10% increase in quantity demanded.
Option 4: 15% increase in quantity demanded.
Question : If the price elasticity of demand for a good is 2.5, then a 10% decrease in price will result in a:
Option 1: 2.5% increase in quantity demanded.
Option 2: 25% increase in quantity demanded.
Option 3: 2.5% decrease in quantity demanded.
Option 4: 25% decrease in quantity demanded.
Question : If the price elasticity of demand for a good is 0.8, then a 10% increase in price will result in a:
Option 1: 0.8% increase in quantity demanded.
Option 2: 8% increase in quantity demanded.
Option 3: 0.8% decrease in quantity demanded.
Option 4: 8% decrease in quantity demanded.
Question : If the price elasticity of demand for a good is -0.5, then a 10% increase in price will result in a:
Option 1: 0.5% decrease in quantity demanded.
Option 2: 5% decrease in quantity demanded.
Option 3: 0.5% increase in quantity demanded.
Option 4: 5% increase in quantity demanded.
Question : Statement 1: If the price elasticity of demand for a product is -1.5, a 10% increase in price will result in a 15% decrease in quantity demanded.
Statement 2: The absolute value of the price elasticity of demand represents the percentage change in quantity demanded for a 1% change in price.
Option 1: Both statements are true.
Option 2: Both statements are false.
Option 3: Statement 1 is true, and statement 2 is false.
Option 4: Statement 1 is false, and statement 2 is true.
