Answer 1

Hey Mate.. !!

Your solution is..!!

Let length of the cloth = x

Cost of cloth per m = y

x * y = 200

y = 200/x ....(1)

Conditions-

1.If the piece were 5m longer

2.Each metre of cloth costed Rs 2 less

(x+5)(y -2) = 200.

xy -2x + 5y -10 = 200

Substituting value of (1)

1000/x - 2x = 200 - 190

1000 -2x²= 10x

500 -x²= 5x

x²+5x - 500 = 0

(x-20) (x+25) = 0

x= 20 (neglecting x= -25)

y = 200/x = 200/20 = 10

Length of the piece of cloth is 20 m and rate per metre is Rs 10.

Hope it help you dear
