Total expenses of a boarding house are partly fixed and partly varying linearly with the number of boarders. The average expenses per boarder is Rs. 700 when there are 25 boarders and Rs. 600 when there are 50 boarders. What is the average expense per boarder when there are 100 boarders?

17500 = x + 25y .....(i)
30000 = x + 50y .....(ii)

X = 5000, y = 50
Now if the average expense of 100 boarders be 'A'
Then 100 x A = 5000 + 500 x 100 ⇒ A = 550
