Sol.  Let us prepare a pictograph first as given below–

                                      Shopkeeper’s Name       Number of Kites Sold  (1    = 50 kites)

                                     Chaman

                                     Rani

                                     Rukhsana

                                     Jasmeet

                                     Jetha Lal

                                     Poonam Ben

                         (a)  6 symbols represent the kites that Rani purchased.
                         (b)  Poonam Ben purchased the maximum number of kites.
                         (c)  In the pictograph, the number of symbols for Jasmeet is more than for Chaman. So, Jasmeet
                             purchased more kites.
                         (d)  Yes, Rukhsana is correct.  Rani purchased 300 kites and Poonam purchased 700 kites. Double
                             of 300 is 600. Clearly, 700 is more than 600.

                      Exercise 4.1

                    1.  The heights of 30 students (all boys) of a class (in cm) are given below:

                       Arrange these heights in a table using tally marks.
                    2.  In a class test, the marks obtained by 40 students out of 10 in English are given below. Arrange these
                       marks in a table using tally marks.

                        (a)  How many students obtained marks below 6?
                        (b)  How many students obtained marks above 6?
                        (c)  How many students obtained marks equal to or more than 4?
                    3.  In a survey of 30 families of a locality, the number of children in each family was noted as follows.

                       Arrange the number of children given above in a table using tally marks.
                    4.  In a village, the number of fruit baskets sold by six fruit merchants in a particular season is given in
                       the following pictograph.

                                    Name of Fruit Merchants   Number of fruit baskets (1    = 100 fruit baskets)
