Question 86(i)
The marks out of 100 obtained by Kunal and Soni in the half-yearly examination are given below:
Draw a double bar graph by choosing appropriate scale.
Steps to construct the bar graphs are as follows:
Step I We draw two lines perpendicular to each other on a graph paper and call them horizontal and vertical axes.
Step II Along the horizontal axis, OX mark the subjects along the vertical axis, OY mark the marks obtained.
Step III We choose a suitable scale to determine the heights of bars. Here, we choose the scale as 1 small division to represent 5 marks.
Step IV First, we draw the bars for Kunal and then bars for Soni for different years.
Bars for Kunal and Soni shaded separately and the shading is shown in the top right corner of the graph paper.
