  1. The cost of carpeting a room 15 meters long with a carpet 75 cm wide at 30 paisa per meter is Rs. 36. The breadth of the room is ?
    1. 6 meters
    2. 8 meters
    3. 9 meters
    4. 12 meters
Correct Option: A

Length of carpet = Total Cost / Rate
= 3600 / 30
= 120 m

Area of carpet = (120 x 75) / 100 m2
= 90 m2
∴ Area of the room = 90 m2

Breadth of the room = Area /Length
= 90 / 15 m
= 6m
