Question
On a particular day, the sales (in rupees) of different items of a baker’s shop are given below.
| ordinary bread | 320 |
| fruit bread | 80 |
| cakes and pastries | 160 |
| biscuits | 120 |
| others | 40 |
|
Total
|
720 |
Draw a pie chart for this data.
Sum
Solution
We find the central angle of each sector. Here the total sale = Rs. 720. We thus have this table.
| Item | Sales (In Rs.) | In Fraction | Central Angle |
| Ordinary Bread | 320 | `320/720 = 4/9` | `4/9xx360° = 160°` |
| Fruit Bread | 80 | `80/720 = 1/9` | `1/9xx360° = 40°` |
| Cakes and pastries | 160 | `160/720 = 2/9` | `2/9xx360° = 80°` |
| Biscuits | 120 | `120/720 = 1/6` | `1/6xx360° = 60°` |
| Others | 40 | `40/720 = 1/18` | `1/18xx360° = 20°` |
Now, we make the pie chart:
