if i correctly understand the problem.........
s = 1/101 + .......+ 1/150
lowest s = 50/101 =1/2
highest s = 50/150 = 1/3
so the range = 1/2 to 1/3

I believe you got it right, HIMALAYA.

yes, if there's no answer choices...this problem will be very difficult and may involve the tools of upper and lower limits ...and we know, to find limits is not easy at all.
