For Roll No. 27-39:

You are required to prepare a simple daily routine chart for your summer holidays and plot a line graph, bar graph, and pie chart using the data.

Here is a sample daily routine chart:

Daily Routine Chart for Summer Holidays

Activity	Time (hours)	Percentage of Day	Angle for Pie Chart
Wake up/Morning routine	2	$8.33\%$	$30^\circ$
Play/Leisure	8	$33.33\%$	$120^\circ$
Study	4	$16.67\%$	$60^\circ$
Sleep	10	$41.67\%$	$150^\circ$
Total	24	$100\%$	$360^\circ$

Plotting the Graphs:

1. Line Graph:

   • Plot the activities on the horizontal (x) axis and the time spent (in hours) on the vertical (y) axis.
   • Mark a point for each activity corresponding to its time duration.
   • Connect these points with lines. This graph will show the variation in time allocated to different activities.

2. Bar Graph:

   • Draw a horizontal (x) axis for the activities (Wake up, Play, Study, Sleep) and a vertical (y) axis for the time spent (in hours).
   • For each activity, draw a bar whose height corresponds to the number of hours spent on that activity.
   • Ensure the bars are of equal width and are separated by equal spaces. This graph visually compares the duration of each activity.

3. Pie Chart:

   • Draw a circle.
   • Calculate the angle for each activity using the formula: $$\text{Angle} = \left( \frac{\text{Time for activity}}{\text{Total time (24 hours)}} \right) \times 360^\circ$$
   • Using a protractor, divide the circle into sectors based on these calculated angles:
     • Wake up/Morning routine: $\left( \frac{2}{24} \right) \times 360^\circ = 30^\circ$
     • Play/Leisure: $\left( \frac{8}{24} \right) \times 360^\circ = 120^\circ$
     • Study: $\left( \frac{4}{24} \right) \times 360^\circ = 60^\circ$
     • Sleep: $\left( \frac{10}{24} \right) \times 360^\circ = 150^\circ$
   • Label each sector with the corresponding activity and its percentage. This chart shows the proportion of the day spent on each activity.
