Question 84(i)
Observe the given data:

Draw a bar graph to represent the above given information.

Answer 1

In order to construct a bar graph representing the above days, we follow the following steps:
Step I Take a graph paper and draw two mutually perpendicular lines OX and OY. Call OX as the horizontal axis and OY as the vertical axis.
Step II Along OX, mark days and along OY, mark number of mobile phone sets sold.
Step III Along OX, choose the uniform (equal) width of the bars and the uniform gap between them, according to the space available for the graph.
Step IV Choose a suitable scale to determine the heights of the bars, according to the availability of space. Here we choose 1 small division to represent 5 mobile sets.
