Tools of Economic AnalysisSection A: answer one question only from this section.
The table below shows the sectoral allocation of a country's budget. Illustrate the data accurately with a pie-chart. Show your workings clearly.
Health: N30 million
Education: N25 million
Housing: N15 million
Manufacturing: N10 million
Agriculture: N20 million
Show the model answer
Model answer
Total budget = 30 + 25 + 15 + 10 + 20 = N100 million
Angle of each sector = amount/total × 360°
Health = 30/100 × 360° = 108°
Education = 25/100 × 360° = 90°
Housing = 15/100 × 360° = 54°
Manufacturing = 10/100 × 360° = 36°
Agriculture = 20/100 × 360° = 72°
Check: total = 360°
Draw a circle, mark the sectors accurately with a protractor, label each sector and give the chart a title
Explanation
Convert each amount to degrees of 360 before drawing.
