The cost of carpeting a room 15 metres long with a carpet 75 cm wide at 30 paisa per metre is Rs. 36.
What is the breadth of the room ?
Rate of laying 75 cm wide strip of carpet is 30 paisa/meter=0.30rupees/m
Therefore cost for 15 meters length(75 cm width)=15*0.30=4.50=C1
Total cost =Rs 36=C
No of stripes=C/C1=36/4.50=8
Total breadth of room=8*0.75=6m
Ans is 6 m

The length, breadth and height of a room are in the ratio 9:7:5. If the breadth and length are doubled while the height is halved. Then what would be the impact on the total area of the 4 walls of the room (in terms of percentage)?
If length, breadth and height of a room are in the ratio 3:2:1. If the breadth and length are halved, while the height is doubled. Then what is the percentage change in the total area of the 4 walls of the room?
