75 persons can sleep in a room 25 m by 9.6 m. If each person requires 16 m3 of the air; find the height of the room.
उत्तर
Let h be the height of the room.
1 person requires 16 m3
75 person requires 75 x 16 m3 = 1200 m3
Volume of the room is 1200 m3
1200 = 25 x 9.6 x h
h = `( 1200 )/( 25 xx 9.6 )`
h = 5 m
