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: 300

remaining 10%=30 seats

i.e., total 100%=10%×10=30×10=300 seats

Answer 2

300 seats.

Explanation:

Percentage:

Percentage of seats filled = 90%

Percentage of empty seats= (100 -90) % = 10%

Let the number of seats in the plane = x

10% of x = 30

`\sf (10)/(100)*x= 30`

`\sf x = 30*(100)/(10)\\\\ x = 300`
