Answer:

let the fixed charge be x

let the charge per day be y

case 1:

x+20y=1000 (1)

x+26y=1180 (2)

subtract eq.1 from eq.2

x+20y=1000

x+26y=1180

- - -

-6y= -180

y= -180/-6

y= 30

put value of y in equation 1

x +20(30)=1000

x+600=1000

x=1000-600

x=400

fixed charge = RS. 400

charge per day= Rs. 30
