There are 35 students in a hostel. If the no. of students increases by 8, the expenses of the mess increase by Rs.42/day while the average expenditure per head diminishes by Rs1. Find the original expenditure of the mess?  Choose the correct choice from the following options:
A) 371.87	B) 400.37	C) 420.37	D) 450.37	E) 480.37
Suppose the average join the mess , total expenditure = 35x + 42   Now, the average expenditure = (35x + 42)/ (35 + 8) = x – 1   or, 35x + 42 = 43x – 43   or, x = 10.625   Thus the original expenditure of the mess = 35 x 10.625 = Rs. 371.87   371.87
