Question

In a plane, 90% of the seats are filled. 30 seats are empty. Find the number of seats in the school.

Answer 1

Answer:

let the total no. of seats in the plane i. a school be 'y'

10 % of y = 30

10 / 100 × y = 30

1/ 10 × y = 30

y = 30×10

y= 300

total no. of seats in plane in the school are 300...
