I remember there seems to be a math problem where several people take a taxi and they get off at different places. How to give the fare fairly? What's this question like?
Taxis are charged by the distance, and the total toll for one third of the distance is 30 yuan, so the first person to get off must pay 10 yuan. The next second third of the journey is also in 30 yuan, which should be shared equally by two people in the car, so the second person has to pay the fare 25 yuan when he gets off the bus; The rest belong to a third person, namely 55 yuan.
