A plane has 360 total seats, which are divided into economy class business class. For every 13 seats in economy class, there are 5 seats in the business class. How many seats are there in each class?
360/(13+5)=20 when economy class has 13 seats, business class will have 5seats, so we can plus two classes seats, than divided. it will became 20part 20*13=260 economy class has 260 seats 20*5=100 business class will has 100 seats
