Question

A plane had 360 total seats, which are divided into economy and business class. For every 13 seats in economy class, there are 5 seats in business class. How many seats are there in each class?

Answer 1

Answer:

Your answer is 20 seats in each class

Answer 2

x+y=360==>y=360-x
x/y=13/5 ==> 5x=13y
5x=13*(360-x)
5x=4680-13x
18x=4680
x=260

y=360-260
y=100
