The given pie chart shows the percentage distribution of the total number of 12th students passed (science and commerce) in five different zone i.e. east zone, west zone, central zone, north zone and south zone and the table chart shows the number of 12th students passed from science department in five different zones.
The total number of students 12th passed = 5000
| Zone |
The number of 12th students passed from science department |
| East | 600 |
| West | 250 |
| Central | 700 |
| North | 850 |
| South | 550 |
If the number of 12th students passed from commerce and art department in north zone is three times the number of 12th students passed from science department in north zones, then the number of 12th students passed from art department from north zone is what percentage of the total number of 12th students including art department passed in north zone?
