i strongly don't agree with the answers stated above.As for
me i think the answers are incomplete because in a question
like this the students have to state the clearly the
mathematical formula for each but as for the deffination of
depreciation all of them are correct because they all accept
the fact that both the fixed and non fixed assets wear and
tear in their values over a period of time. but still if you
buy a perishable raw material for say production and you
don't store it in a save place and by the time you want the
material the initial value is not there is that not
depreciation.So what i am saying is depreciation is not
necessary loss in the value of fixed assets of e.g.
enterprise e.t.c.
