Solution

The measures of central angles are given  in the table.

Age group(Yrs) No. of persons Central Angle
20 - 25 80
\[\frac{80}{200} \times 360 = 144^\circ\]
25 - 30 60
 
\[\frac{60}{200} \times 360 = 108^\circ\]
 
30 - 35 35
 
\[\frac{35}{200} \times 360 = 63^\circ\]
35 - 40 25
 
\[\frac{25}{200} \times 360 = 45^\circ\]
Total 200
