Question
Medical check up of 180 women was conducted in a health centre in a village. 50 of them were short of haemoglobin, 10 suffered from cataract and 25 had respiratory disorders. The remaining women were healthy. Show the information by a pie diagram.
Solution
The measures of central angles are given in the table.
| Health condition | Number of women | Central Angle |
| Short of haemoglobin | 50 | `50/180 xx 360 = 100°` |
| Suffered from cataract | 10 | `10/180 xx 360 = 20°` |
| Respiratory disorders | 25 | `25/180 xx 360 = 50°` |
| Healthy | 95 | `95/180 xx 360 = 190°` |
| Total | 180 |
