Answer:
800
Let us take x as the total expense of mess initially and y as the average expense
Then,
Initially, x/40=y
x=40y
After 5 more were added the total expense increased by 55,ie, x+55 and average expanse was decreased by 1, ie, y-1
Therefore the conditions are
(x+55)/45=y-1
x+55=45y-45
40y+55=45y-45
5y=100
y=20
Hence, the total initial expense was 40y=800
