Now I'm getting worried, this question also seems suspect to me:

5 pieces of wood have an average (arithmetic mean) length os 124 cm and a median lenght of 140 cm. What is the maximum possible lenght, in cm, of the shortest piece of wood?

A) 90
B) 100
C) 110
D) 130
E) 140

I get that the 2 woods below the median sum to 200...I don't understand how BOTH being 100 in length allows the question to say that there is a SHORTEST piece of wood. If both are 100 then there is not shortest piece...so I picked A, but obviously this is wrong. WTF?

I agree with your interpretation, but the people who wrote the question get to invent their own rules. Just move on.

just like you could say 140 as the longest, even when you have 3 140s. its fair.

Let the pieces be a, b, c, d, e arranged from shortest to longest.

Then c must be equal to 140, the median; And a 248

A 90 --> if a=90, b [color=#FF0000]if a=100, b [color=#FF0000]if a=110, b [color=#FF0000]if a=120, b [color=#FF0000]if a=140, b<=108. Then 140 is not the shortest length anymore

Is it C then?
