                    Pie Chart

                    A pie chart, also called a pie graph or circle graph, is a circular chart that is divided into sectors
                    or parts in which the area of each sector represents the size of the data. Pie charts are used to
                    compare different parts of a whole.

                    Now let’s learn how to interpret the information given in a pie chart.
                    Example 6:  The given pie chart shows different flavours of juices
                                  liked by some students. Read it carefully and answer                       Orange
                                                                                                               20
                                  the following questions.                                          Mango
                                                                                                     15
                                  (a)   Which is the most liked flavour of juice among the                         Guava
                                                                                                                    5
                                       students?                                                       Litchi  Pineapple
                                                                                                        10      10
                                  (b)  How many students like mango juice?

                                  (c)  Which two flavour of juices are liked by equal number of students?

                    Solution:     (a)  Orange juice is the most liked among the students.
                                  (b)  15 students like mango juice.

                                  (c)   Litchi and pineapple juices are liked by equal number of students.

                                  information about percentage of number of students
                                  having different hobby classes for the session. Read
                                                                                                               Art
                                  the pie chart carefully and answer the following                             30%

                                  (b)   Which hobby classes are attended by the same
                                       number of students?

                                  (c)  Find the fraction of the number of students attending all the four classes.

                                       (Hint: Divide the given percentage by 100 to get the fraction.)
