Draw bar graphs to represent the data.

Answer:

We go through the following steps to construct the bar graphs :

(a) We draw two lines perpendicular to each other on a graph paper and call them horizontal and vertical axes as shown in Fig. below:

(b) Along the horizontal axis, we mark the 'years' and along the vertical axis, we mark the 'pass percentage'.

(c) We choose a suitable scale to determine the heights of bars. Here/ we choose the scale as 1 big division to represent 10.

(d) First we draw the bars for Class X results and then bars for Class XII results for different years.

Bars for X and XII class results are shaded separately and the shading is shown in the top right corner of the graph paper.
