A country has a total area of $150{,}000$ km² and a total population of $50{,}000{,}000$. The population is distributed among three zones:\n- Coastal zone: area $30{,}000$ km², population density $800$ persons/km².\n- Highland zone: area $50{,}000$ km², population density $300$ persons/km².\n- Interior zone: area unknown.\nUrbanisation rates are: 40 % of the coastal population lives in cities, 25 % of the highland population, and 15 % of the interior population. Determine the area of the interior zone, its population density (rounded to the nearest whole person per km²), and which zone contributes the greatest number of urban dwellers.
