Four friends A, B, C and D are buying a car together.
They agree that everyone should have one of the first four rides are all alone.
But the following mandatory conditions apply:
1. If D is allowed to get on the first trip, so would C have the third trip.
2. If A or D, will have the second trip, so would C have the first trip.
3. If and only if A receives the third trip, would B want to have the second trip.
4. Will D get the third trip, A wants the second trip.
5. Will D get the last trip would C have the third and A the first.
In what possible orders should they drive the car the four first trips so everyone is happy?
Are there multiple solutions? Justify our answer.
Good luck, folks!!
