Question

The number of ATMs of different banks in a city is shown below:

Bank	Number of ATMs
Syndicate Bank	5
Dena Bank	15
Indian Bank	20
State Bank of India	25
Vijaya Bank	10

Draw a bar graph to represent the above information by choosing the scale of your choice.

Answer 1

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 bank names and along OY, mark number of ATMs.

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 represents 5 ATMs.

Step V: Calculate the height of various bars as follows:

Bank	Height of bars
Syndicate Bank	`5/5` = 1 unit
Dena Bank	`15/5` = 3 units
Indian Bank	`20/5` = 4 units
State Bank of India	`25/5` = 5 units
Vijaya Bank	`10/2` = 2 units

Hence, the required bar graph of given data is shown below

Scale: 1 unit length = 5 ATMs
