# Inversely Proportional

Unitary method is the one where we find the value of the required number of quantity by first finding the value of the unit quantity. This can be divided into two types, which are direct variation and inverse variation.

Let us consider the real life situation. If two taps having the same capacity can fill a tank in 30 minutes, how long will it take for a single tap to fill the tank? If there are three such taps how long will it take for the three taps to fill the tank. How do we solve such type of problem? We can easily solve these types of problems if we understand the basic definition and equation of inverse proportion. We shall also discuss with some of the interesting examples on inverse proportion.
