Question 1 Report

The table below shows the age distribution of hypothetical population.

Present this information in the form of a pie chart. Show your workings clearly.

Answer

Answer Details

For a pie chart, the angle for each sector is:

\[\text{Sector angle}=\frac{\text{Number of people in the group}}{\text{Total population}}\times360^\circ\]

The number aged 60 and above is \(8.25\) million, since \(20.90+13.75+12.10+8.25=55.00\) million.

Age group	Population (million)	Working	Angle for pie chart
Under 20	20.90	\(\frac{20.90}{55.00}\times360^\circ\)	\(136.8^\circ\)
20–29	13.75	\(\frac{13.75}{55.00}\times360^\circ\)	\(90.0^\circ\)
30–59	12.10	\(\frac{12.10}{55.00}\times360^\circ\)	\(79.2^\circ\)
60 and above	8.25	\(\frac{8.25}{55.00}\times360^\circ\)	\(54.0^\circ\)
Total	55.00		\(360.0^\circ\)

The completed pie chart is shown below.
