Five pieces of wood have an average length of 126cm and a median length of 140cm. What is the maximum possible length, in cm, of the shortest piece of wood?  Select:
A) a) 90  B) b) 105  C) c) 110  D) d) 130  E) e) 140
B. 105   sum of all lengths of all 5 pieces of wood = 126 * 5= 
<gadget id="calculator">126 * 5</gadget>
<output>630</output>
630   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= 
<gadget id="calculator">140 * 3</gadget>
<output>420</output>
420   sum of first 2= 630 - 420= 
<gadget id="calculator">630 - 420</gadget>
<output>210</output>
210   each of these 2 will have length 210/2= 
<gadget id="calculator">210/2</gadget>
<output>105</output>
105   Aswer b) 105
<result>B</result>
