Inverse Variation


The statement ” y varies inversely as x means that when x increases,y decreases by the same factor. In other words, the expression xy is constant:


Example :

In a factory, 10 men can do the job in 30 days. How many days it will take if 20 men do the same job?

Here, when the man power increases, they will need less than 30 days to complete the same job. So, this is an inverse variation.
