Represent the data through pie chart.

We have collected some data about rivers which is as under:

Rivers                                          % Polluted

Ganga                                            36

Brahamputra                                  12

Godavri                                           12

 Indus                                               1

Krishna                                             12

Mahanadi                                          4

 Rest rivers                                         22

We have to use percentages as quantities in the pie chart.

There are different ways by which pollution can be reduced which are:

• Strong implementation of penalties on the industries which are not following rules regarding pollution,
• Spread awareness among people in the society.
• Curb corruption in the country.
