Hmm bye sir please tell me what is the

Answer 2

Answer:

Passenger on a train = (5b-13b)

passenger board at first stations = (4a-2a)

passenger board at second stations = (5b-2a)

first we will find total passenger board at both stations = (4a-3b)+(5b-2a)

=(2a+2b)

number of passengers on the train now

= (10a+13b)+(2a+2b)

=(12a+15b)
