Solution
In order to construct a bar graph representing the above data, we follow the following steps:
Step I: Take a graph paper and draw two mutually perpendicular lines OX and OY. Let OX as the horizontal axis and OY as the vertical axis.
Step II: Along OX, mark sources and along OY, mark income.
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 unit length to represents Rs. 10000.
Step V: Calculate the various bars as follows:
| Sources | Height of bars |
| Income from local taxes | `75000/10000` = 7.5 units |
| Funds received from government | `150000/10000` = 15 units |
| Donations | `25000/10000` = 2.5 units |
| Income from other resources | `50000/10000` = 5 units |
Hence, the required bar graph for the given data is shown below
Scale: 1 unit length = ₹ 10000
