Answer 2

Given :-

in an auditorium 1/3 of 900 seats are empty ,2/3 of total are filled after one hour .

To find :-

how many  seats were filled.

Solution :-

⇒ number of seats empty =  900 × 1/3 = 300

Therefore 300 seats are empty.

⇒ number of occupied seats = number of total seats - number of empty seats

therefore ,

⇒ number of occupied seats = 900 - 300 = 600
