<human>:  A bus has a capacity of 200 people. If it carried 3/4 of its capacity on its first trip from city A to city B and 4/5 of its capacity on its return trip, calculate the total number of people the bus carried on the two trips?
<bot>: How many passengers did the bus carry from city A to city B? ** From city A to city B, the bus carried 3/4*200 = <<3/4*200=150>>150 passengers
How many passengers did the bus carry on the return trip? ** On the return trip, the bus carried 4/5*200 = <<4/5*200=160>>160 passengers
How many passengers did the bus carry in total? ** In total, the bus carried 160+150 = <<160+150=310>>310 passengers.
