Question

The cost of carpeting a room 15m long with the caroet of width 75cm at ₹ 80 /m is ₹ 19200 . Find the width of the room

Answer 1

Given length of the room = 15m

Width of the carpet = 75 cm = 75/100 m = 3/4 m     (since 100 cm = 1 m. So 75 cm = 75/100 m)

Let length of the carpet is L.

Given cost of the carpet per meter = 80 rupees

Cost of the carpet required for the room = 80*L

Again given that total cost of the carpeting = 19200

So 80*L = 19200

=> L = 19200/80

=> L = 240 m
