                    Look at the pictograph and answer the following questions:
                    (a)  How many orange trees are there in the orchard?

                    (b)  What is the total number of fruit-trees in the orchard?

                    (c)  How many more apple trees are there than mango trees?
                    (d)   The number of which two types of trees together is equal to the number of

                        guava trees in the orchard?

              Bar graPh


              A bar  graph  is  another  way of representing  data.  Representation  of data with  the
              help of bars (rectangles) in a diagram is called a bar graph or bar chart.
              Every bar graph has:

                    (a)  a title explaining the information given in the graph.
                    (b)  the horizontal and vertical axes.

                    (c)  labels explaining  the meaning of each bar.

                    (d)  a scale that is chosen for the given data.
              A bar graph can be drawn horizontally or vertically using graph paper, a ruler and a
              pencil.  The width  of each bar  is  uniform. The bars are drawn  leaving  equal  spaces

              (gaps) between them.

              The marks obtained  by Riya in  the unit  tests of  different subjects  in the month  of
              August are given in the following table.

              The      bar    graph      drawn      alongside

              represents  the  marks obtained  by Riya             10 Y   Marks Obtained by Riya in the Unit Tests
              in the unit tests.                                    9
