1.	Following is the data regarding pass percentage of students in different classes.Draw a vertical bar graph to represent the above data.
Answer» Bar graph showing pass percentage of different classes from VI to X. Steps of construction: 1. Draw two mutually perpendicular lines on a graph sheet – one horizontal (X-axis) and one vertical (Y-axis) mark. Number of class on the X-axis and their pass percentage on the Y-axis. 2. Take the 10 as scale on the Y-axis i.e., 1 cm = 10% 3. Calculate the lengths or heights of the bars by dividing the pass percentage with the scale. Class VI = 65 ÷ 10 = 6.5 cm Class VII = 75 ÷ 10 = 7.5 cm Class VIII = 85 ÷ 10 = 8.5 cm Class IX = 60 ÷ 10 = 6 cm Class X = 80 ÷ 10 = 8 cm 4. Draw rectangular vertical bars of same width (I cm) on the X-axis with their calculated heights. Hence, required vertical bar graph was constructed.

Bar graph showing pass percentage of different classes from VI to X.

Steps of construction:

1. Draw two mutually perpendicular lines on a graph sheet – one horizontal (X-axis) and one vertical (Y-axis) mark. Number of class on the X-axis and their pass percentage on the Y-axis.

2. Take the 10 as scale on the Y-axis i.e., 1 cm = 10%

3. Calculate the lengths or heights of the bars by dividing the pass percentage with the scale.

Class VI = 65 ÷ 10 = 6.5 cm

Class VII = 75 ÷ 10 = 7.5 cm

Class VIII = 85 ÷ 10 = 8.5 cm

Class IX = 60 ÷ 10 = 6 cm

Class X = 80 ÷ 10 = 8 cm

4. Draw rectangular vertical bars of same width (I cm) on the X-axis with their calculated heights.

Hence, required vertical bar graph was constructed.
