None. An empty bus can not pull up to a bus stop.

Bus was empty
1) 20 people get in.
2) At next stop Number of peple get off 10. So now in bus there is only 10 people left.
The number of people get in was twice the number get in on first i.e (20X2 ) 40. So total people in bus was 40 + 10 = 50.
3) At the third stop 50 person get off so there shall be no passenger in the bus except Bus driver/conductor.

There are none in the bus expect the driver and the conductor.

2
driver and conductor

only conductor and driver
