Five pieces of wood have an average length of 120cm and a median length of 140cm. What is the maximum possible length, in cm, of the shortest piece of wood?  Choose the correct option:
A) a) 90  B) b) 100  C) c) 110  D) d) 130  E) e) 140
A. 90   sum of all lengths of all 5 pieces of wood = 124 * 5 = 600   3rd piece (sorted in increasing length) length = 140 (median)   for sum of first 2 wood length to become max, last two should be least.   let 4th, 5th wood also have length 140 each.   total of last 3 = 140 * 3=

420   sum of first 2= 600 - 420= 
<gadget id="calculator">600 - 420</gadget>
<output>180</output>
180   each of these 2 will have length 180/2=
