Solution
a. Steps to construct the bar graph 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 hill stations and along the vertical axis, OY mark the tourist visitors.
Step III: We choose a suitable scale to determine the heights of bars. Here, we choose the scale as 1 small division to represent 400 tourists.
Step IV: First, we draw the bars for year 2008 and then bars for year 2009 for different hill stations.
Bars for years 2008 and 2009 are shaded separately and the shading is shown in the top right corner of the graph paper.
b. It is clear from the given data that in year 2008 tourists visit Mussoorie the most maximum.
c. It is clear from the given data that in year 2009 tourists visit Manali the least.
d. From the graph, we can say that in 2009, there is increase in tourist visitors in the places; Manali, Nainital, Mussoorie and Kullu.
