ELASTICITY OF DEMAND

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If a 10 percent increase in the price of a good leads to a 25 percent decrease in the quantity demanded of a good, demand is:
A
Relatively inelastic
B
Relatively elastic
C
Perfectly elastic
D
Perfectly inelastic
Explanation: 

Detailed explanation-1: -The demand for a good is inelastic if the percentage decrease in the quantity demanded is less than the percentage increase in its price. In this example, a 10 percent price rise brings a 2 percent decrease in the quantity demanded, so demand is inelastic.

Detailed explanation-2: -Inelastic demand occurs when changes in price cause a disproportionately small change in quantity demanded. For example, a good with inelastic demand might see its price increase by 30%, but demand falls by only 10% as a result.

Detailed explanation-3: -Perfectly Elastic (PED > 1) If the percentage of change in demand is more than the percentage of change in price, then the demand is perfectly elastic. For instance, if a 10% increase in price causes a 20% drop in demand, then the coefficient of PED is 3, which means that the demand is perfectly elastic.

Detailed explanation-4: -When the price of a good rises from Rs. 10 per unit to Rs. 12 per unit, its quantity demanded falls by 20 per cent.
