Five pieces of wood have an average length of 128cm and a median length of 140cm. What is the maximum possible length, in cm, of the shortest piece of wood?
Options.
A) a) 90 B) b) 100 C) c) 110 D) d) 130 E) e) 140
C. 110   sum of all lengths of all 5 pieces of wood = 128 * 5= 
<gadget id="calculator">128 * 5</gadget>
<output>640</output>
640   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= 640 - 420= 
<gadget id="calculator">640 - 420</gadget>
<output>220</output>
220   each of these 2 will have length 220/2= 
<gadget id="calculator">220/2</gadget>
<output>110</output>
110   Answer c) 110
