# Concept of Commission

A commission is the payment an agent gets for selling or buying something on behalf of another person.
It is usually written as a percentage of the cost price or selling price.

Example:
An agent got 2% commission for selling a plot for Rs.1000000. Find his commission.
Solution:
Let       Sale Price = 1000000
Commission Rate = 2%
Amount of Commission = 2% x 1000000 = $\frac{2}{{100}}$x 1000000 = 20000

Example:
An agent received Rs.6000 as commission for selling a house. If his commission rate is 2%, what is the selling price?
Solution:
Let       Selling Price = $x$
Commission Rate = 2%
Commission = (Selling Price)(Rate)
6000 = $x$x $\frac{2}{{100}}$
$\boxed{x = 300000}$
