Question
Distinguish between :
Percentage method of counting elasticity of demand and Geometric method of counting elasticity of demand.
Solution
Basis of Difference  Percentage method of counting elasticity of demand  Geometric method of counting elasticity of demand 
Method  \[E_d = \frac{\text { Percentage change in demand}}{\text { Percentage change in price}}\]

\[E_d = \frac{\text { Lower segment of the demand curve}}{\text { Upper segment of the demand curve}}\]

Also known as  Arithmetic method  Point elasticity method
