Question

The following table shows the ages of five people, illustrates this data using a Bar graph, and tell who is twice as old as $\mathrm{B}$?

Name of Persons	$\mathrm{A}$	$\mathrm{B}$	$\mathrm{C}$	$\mathrm{D}$	$\mathrm{E}$
Ages in Years	$35$	$25$	$40$	$30$	$50$

Answer 1

To draw the bar graph, we will write the name of persons along the X-axis and will plot values of ages along the Y-axis. Along the Y-axis we will choose the scale as ten small divisions equal to $10$years. Then on plotting all the values we will get the bar graph as shown below.

From the bar graph, the height of bar $\mathrm{E}$ is double of $\mathrm{B}$, So the age of $\mathrm{E}$ will be twice of $\mathrm{B}$.
