Answer:

Let the fixed charge be x and additional charge be y per day both in Rs.

For Reema, number of days =6=2+4

Therefore, charge x+4y=22

⇒x=22−4y ....(1)

For Ruchika, number of days =4=2+2

Therefore, charge =x+2y=16

⇒ x=16−2y ....(2)

Comparing (1) and (2), we have

22−4y=16−2y

⇒ y=3

Substituting this value of y in equation (1), we have

x=22−4×3=10

So, fixed charge = Rs. 10

and additional charge = Rs. 3 per day.

Hope it helps...
