| Bank | State Bank of India |
Bank of Baroda |
Punjab National Bank |
Canara Bank |
| Number of Branches | 30 | 17 | 15 | 10 |
Draw a pie chart for this data.
Solution
Total number of branches = 30 + 17 + 15 + 10 = 72
| Bank | Number of branches | Central angle |
| State Bank of India | 30 | `30/72 xx 360^circ = 150^circ` |
| Bank of Baroda | 17 | `17/72 xx 360^circ = 85^circ` |
| Punjab National Bank | 15 | `15/72 xx 360^circ = 75^circ` |
| Canara Bank | 10 | `10/72 xx 360^circ = 50^circ` |
