The cost of carpeting a room 15 metres long with a carpet 75 cm wide at 30 paisa per metre is Rs. 36. The breadth of the room is

OPtion

1) 3 metres
2) 6 metres
3) 8 metres
4) 9 metres
5) 10 metres
6) 11 metres
7) 12 metres
8) 14 metres
9) 16 metres
10)None of these

Solution

Length of the carpet = Total cost / Rate = 3600/30 = 120 m
Let breadth of the room be x metres
Then 120*75/100 = 15*x or x = 6 metre

optoin 2)

Correct Option: 2 Best Solution (26)

RANJAN FADIA   9 years AGO

total lengths of carpet in room = 36/.30 =120 mtr .

so how much carpet used = 120 * 0.75 = 90 mtr sq
that is breadth of room = 90 / 15 =6 mtr ans

Yashi Das   9 years AGO

Length of the carpet= total cost/(rate/m) = 3600/30= 120m
Area of the carpet =(120*(75/100))=90m^2
Therefore,Breadth = Area/ length =90/15 =6 m

ramakrishnateja   9 years AGO

here the area of carpet= area of room. ,area of room=l*0.75m^2
area of room=15*bm^2. let breadth=bm.
length of carpet=totalcost of carpenting/cost per meter
hence length of carpet=3600/30=120m.
hence 15*b=120*0.75.b=6m.

Shubham Raj   9 years AGO

The breadth of the room is Area of room = length * bredth Total length of carpet : 36/.3 = 120 meters
Total area of carpet used :=.75 * 120= 90 sqmeters.
Thus width of the room = 90/15= 6 meters
width = 6 meters

Breadth =6.0meters
carpet strip width=0.75 meter
No of strips:6.0/0.75=8nos
Total cost =LxNo of stripxrate per strip
=15x8xo.30
=36
hence proved

Robert Yogenson   9 years AGO

30 paisa per minute=36 and change into rupees 36/30=1.2x100=120 (is called length of carpet)
Area of carpet=.75mX120=90
then breadth of room=90/15=6 m(because both area will be equal )

Length of the carpet= Total cost/ rate/m= 3600/45=120m

Ruby kaushik   9 years AGO

length of carpet = total cost/(cost/m) = 3600 / 30 = 120 m
area of carpet = 120*75/100 = 90 m
breadth of room = area/length = 90/15 = 6m
so answer is option 2

sumit kumar   9 years AGO

.30 rupess for 1 meter carpet
so in 36 rupees carpet length is (1/.30)*120=120m
according to question
area of room=area of carpet
15*x=120*.75
x=6m

S.Hemanth kumar   9 years AGO

R.S is 36 per meter is 3600 per 30 paisa so 3600/30=120m
Area= 120*75*10^-2=90
breadth of the room = 90/15=6m
so Ans) 2

Chandrajeet Yadav   9 years AGO

let length of carpet and breadth of room is x and y meter respectively.
then, 30 * x = 36*100
so, x = 120

Now, 15 * y = 120 * 0.75 * 100
so, y = 6

So breadth of the room = y = 6 meter

option (2

rakesh sharma   9 years AGO

30/100 rupess ....1meter
1 rupess................100/30
then 36rupesss.......(100/30)*36=120 meter carpet used
so 0.75*8=6 only one option is setisfy this situation
so answer option (2) is correct

area of room = length * bredth
total length of carpet = 36/.3 = 120 meters
total area of carpet used = .75 * 120 = 90 sqmeters
thus width of the room = 90/15 = 6 meters

Arnab Maity   9 years AGO

Area of room = length * breadth
Total length of carpet => 36/.3 = 120 metres
Total area of carpet used => 0.75 * 120= 90 sqmetres.
Thus breadth of the room => 90/15= 6 metres.
Answer) option 2) breadth of the room is 6 metres.
