उत्तर

Steps to construct the bar graphs are as follows:

Step I: Firstly, 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, we mark the foodstuff and along the vertical axis, we mark the intake of nutrients (calories).

Step III: We choose a suitable scale to determine the heights of bars. Here, we choose the scale as 1 small division to represent 20.

Step IV: First, we draw the bars for rural and then bars of urban for different foodstuff.

Bars for rural and urban are shaded separately and the shading is shown at the top right corner of the graph paper.
