note that as r is a positive integer so {x+r} = {x}
=> [x] + {x} *2000/2000 = x.

After simplifying,we get.....
(2000[x]+x+1-[x+1]+x+2-[x+2]........+x+2000-[x+2000])/2000

[x+n]=[x]+n....where n is an integer
Applying this in d above eq. we get.....2000x/2000=x
Thus d value of above expression is x.
