Dude, why don't you do a google search for your questions. You will notice that most of them have already been answered in the manhattan forums itself.

I would go with B

Sum of the five pieces of wood would be 620 centimeters
if median length is 140 centimeters, maximum possible length of the shortest piece of wood would be 100.
100,100,140,140,140 total 620

I am not sure if its helpful or correct, however, I tried :) lets wait for an expert's answer

total wt = 620

x + y + 140 + 140 + 140 = 620 ...for having the intial as max the later shud be minimum..


therefore >> x + y = 200

thus max possible = 100
