Question. Records of students in a school during various academic years are as follows. Represent the data in the form of bar graph.
 

Answer:
To draw the bar graph:
1. Draw two perpendicular lines on graph paper, one horizontal (x-axis) representing "Academic Year" and one vertical (y-axis) representing "No. of Students".
2. Choose a suitable scale for the vertical axis, e.g., 1 unit length = 500 students.
3. Calculate the heights of the bars:
- For 2004-05: \(1500 / 500 = 3\) units
- For 2005-06: \(2000 / 500 = 4\) units
- For 2006-07: \(2400 / 500 = 4.8\) units
- For 2007-08: \(3000 / 500 = 6\) units
- For 2008-09: \(3700 / 500 = 7.4\) units
4. Draw bars of uniform width with equal spacing between them.

Question. Population of Delhi in five different census years is given below. Represent the data with the help of bar graph.
 

Answer:
To draw the bar graph:
1. Draw two perpendicular axes: the horizontal axis (x-axis) for "Census Years" and the vertical axis (y-axis) for "Population in Lakhs".
2. Choose a scale for the vertical axis, e.g., 1 unit length = 20 Lakhs.
3. Calculate the heights of the bars:
- For 1951: \(30 / 20 = 1.5\) units
- For 1961: \(55 / 20 = 2.75\) units
- For 1971: \(75 / 20 = 3.75\) units
- For 1981: \(120 / 20 = 6\) units
- For 1991: \(180 / 20 = 9\) units
4. Draw bars of uniform width with equal spacing between them.

2. Choose a scale for the vertical axis, e.g., 1 unit length = 10 enrolment.
3. Calculate the heights of the bars:
- For Class VI: \(60 / 10 = 6\) units
- For Class VII: \(45 / 10 = 4.5\) units
- For Class VIII: \(40 / 10 = 4\) units
- For Class IX: \(35 / 10 = 3.5\) units
- For Class X: \(30 / 10 = 3\) units
4. Draw bars of uniform width with equal spacing between them.

Question. The following table gives the expenditure on development plan of a Company during various years. Represent the data on a bar chart.
 

Answer:
To draw the bar chart:
