Let,
the fixed charge = Rs. x
the cost of food per day = Rs. y
When Yash takes food for 25 days, he has to pay Rs. 2200 as hostel charges.
Therefore we get,
x + 25y = 2200 .........(i)
When Niyati takes food for 20 days, he has to pay Rs. 1800 as hostel charges.
Therefore we get,
x + 20y = 1800 .........(ii)
Solve equation (i) and (ii) simultaneously, we get
x = 200 and y = 80
Therefore the fixed charge is Rs. 200 and the cost of food per day Rs. 80.
