Answer

let the cost of 'x' m cost rs35

and y be the cost of 1m cloth

therefore

xy=35

y=35/x

according to the question

(x+4)(y-1)=35

(x+4)(35/x-1)=35

(x×35/x)-x+(4×35/x)-4=35

35-x+140/x-4=35

-x^2+140-4x ÷ x=35-35

-x^2+140-4x=0

x^2+4x-140=0

x^2+14x-10x-140=0

x (x+14)-10 (x+14)=0

(x-10)(x+14)=0

x=10

y=35/10=3.5

therefore 10m cloth cost Rs35

and cost of 1m cloth is Rs3.5

please mark my answer as brainlest
