computers have elastic demand and pharmaceutical have inelastic demand if the supply of both changes then whose price will increase more

If the supply of both changes, the computer price will increase more since it has an elastic demand.

Explanation:

Price elasticity of demand can be defined as a measure of how much the demand of a good or service changes with a corresponding change in price. It tries to estimate how much the consumers respond in terms of demand when the price of a good or service changes. The formula for determining the price elasticity of demand is as follows;

E=%D/%P

where;

E=price elasticity of demand

%D=percentage change in the demand which is given as;

%D={ (final demand-initial demand) / initial demand}*100

%P=percentage change in price which is given as;

%P={ (final price-initial price) / initial price}*100

The measure for the price elasticity of demand is absolute. A good or service can either be elastic or inelastic. A good that is elastic is one whose price elasticity of demand is greater than 1 which means that it's demand is highly responsive to changes in price. On the other hand, a good that is inelastic is one whose price elasticity of demand is less than 1 means that the changes in price do not affect it's demand.
