Question

A 800 seat movie theatre is divided into 3 theatres. There are 270 seats in Theatres 1, and there are 150 more seats in Theatre 2 than in Theatre 3. How many seats are in theatre 2?​

Answer 1

Step-by-step explanation:

Total seats=800

Let seats in 3=x

So seats in 2=x+150

Now,seats in 2+3

=total seats in theatre - seats in 1

=X+x+150=800-270

=2x+150=530

=2X=530-150

=2X=380

=X=380/2

=X=190

So seats in 2=x+150

=190+150

=340
