Question

A plane has 360360360 total seats, which are divided into economy class and business class. For every 131313 seats in economy class, there are 555 seats in business class. How many seats are there in each class?

Answer 1

There are 260 seats in economy class and 100 seats in business class.

Explanation:

Answer 2

When we have a set divided by a proportion or ratio, we assume a simultaneous increase for each subset, that is, we get an equation like this:

`T=Ax+Bx+Cx+...`

Where T is the total number of objects in the set, the letters A, B, C, etc., the proportions or ratios of each subset and x the number of times each set must increase to reach the total T, in this case:

`T=360\\A=13\\B=5`

Now we solve

`360=13x+5x\\360=(13+5)x\\(360)/(18)=x\\ x=20`

That is, each set must increase 20 times to reach the total seats.

The answer is that there are 13*20=260 seats in economy class and 5*20=100 in business class

If the question is with the data 360360360, 131313 and 555, the problem does not have an exact solution
