Minimum Number of Direct Flights Calculation:

To ensure that any person can make a trip from any city to any other city in the morning and return by the evening on the same day, we need to calculate the minimum number of direct flights required.

Calculation:
- Since there are 10 cities in total, each city needs to have direct flights to every other city.
- Therefore, for each city, there will be 9 direct flights to connect it to the other 9 cities.
- However, this counts only one leg of the journey. To complete the round trip, we need an additional set of 9 direct flights.
- So, for each city, there will be a total of 18 direct flights (9 for outbound journey and 9 for the return journey).

Total Number of Direct Flights:
- For 10 cities, each requiring 18 direct flights, the total number of direct flights needed can be calculated as:
10 cities * 18 direct flights per city = 180 direct flights

Therefore, the minimum number of direct flights to be scheduled to satisfy the underlying principle is 180.
