An empty bus pulls up to a stop and 20 people get on. At the next stop 10 people get off and twice as many people get on as at the first stop. At the third stop 50 get off.

How many people are on the bus at this point?

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.
