Question

In a plane, 90% of the seats
are filled. 30 seats are
empty. Find the number of
Seats on the plane.​

Answer 1

Answer:

Let the total number of seats = x

100% - 90% = 10%

10% of seats are empty.

30 seats are empty.

Now,

We can write that :

10% of x = 30

10% × x = 30

10/100 × x = 30

x = 30 × 100/10

x = 30 × 10 = 300

The total number of seats = x = 300
