The following table shows the number of students in a school playing five different games Games Football Hockey Cricket Tennis Squash Number of students 200 175 250 75 50 Present the information on a bar graph

Take the games along the x-axis and the number of students. Take the scale as 25 students 5 small division

The following table shows how a student spends his pocket money during the course of a month Items Food Entertainment Other expenditures Savings Expenditure 40 % 25 % 20 % 15 % Represent it by a pie-diagram.

Here, total expenditure = 100 % So, the central angle = ( component value / 100 ) × 360 ° The central angle for each activity will be calculated as follows Items Expenditure Central Angle Food 40 % 40 100 × 360 ° = 144 ° Entertainment 25 % 25 100 × 360 ° = 90 ° Other Expenditure 20 % 20 100 × 360 ° = 72 ° Savings 15 % 15 100 × 360 ° = 54 ° Steps of construction → Calculate the central angle for each component, as shown in the previous step. → Draw a circle of appropriate radius. Radius = Diameter 2 → Within this circle, draw a radius. → Draw another radius making central angle of first component with drawn radius, this sector represents the first component. From this radius, draw next radius with central angle of second component, this sector represents second component and so on, until we finish all the components. → Shade each sector differently and mark the component it represents. → Give heading in the pie-chart as shown below.
