There are 13 people on the city bus. at the first stop, four people get off and to get on. at the second stop, six people get off. if there are 12 people on the bus after the second stop, how many got on then?

9 people should get on stop 1.

Step-by-step explanation:

If i understood it correctly .

13 people on bus initially.

at first stop - 4 people get off . So 9 people should be on bus.

But few get in bus ( that is what is asked in the question - but it is not super clear to me)

after 2nd stop - there are 12 people on bus.

at 2nd stop  6 people got off.. so there were total of 18 on the bus

So if there were 9 people on bus stop by stop 1 .. so 9 people should have got in bus at stop 1 to make it equal to 18.

Only doubt i have is  : if the question is asking how many got on the 2nd stop.  also i was not clear what does this line means - At the first stop, four people get off and to get on.
