since per km is a milestone, 100 km will have obviously 100 milestones, but still there are two possibilities:
a) if two extreme milestones(0th and 100th km) are considered then sum is = 101.
b) if extreme milestones are removed then sum is = 99.
Else u consider any other case, then its nt possible to find middle milestone to start with...
Considering case a): we have 50-50 milestones at each side to paint excluding middle, it is assumed he is already there. Hence simple calculation results in (50+50)x2 = 200 times. But question is after painting last milestone, why he will return to the middle milestone. I think answer must be 200-1 = 199.
