Elasticity is defined as the ratio of
percentage(%) change in the quantity due to
percentage(%) change in the price, or in other
words it basically implies the degree of
responsiveness of percentage(%) change in
quantity demanded to the % change in price.
Elasticity is of 3 types:
• Elastic
• Inelastic
• Unit Elastic
Step2
b)
Elasticity is calculated with the given formula:
Elasticity=
% change in quantity demanded
% change in price
OP
dP
OP
dP
where,
P = Price
Q = Quantity
dP/dQ = slope of the demand curve
Substituting the value in the given formula,
one can get:
100
ed =
40
= - 1. 25
leal = 1. 25
The absolute value of elasticity is 1.25 which is
greater than 1, which implies that it is elastic
in nature, which means that as price changes,
quantity changes more than proportionate.
