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?
Correct Answer: 6 meters
Explanation:
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
