1. Ans.(c)
Sol. Average of the total production during the given period,
In 2008 = 8 + 16 + 21 + 4 + 25 = 74
In 2009 = 20 + 10 + 17 + 6 + 18 = 71
In 2010 = 16 + 14 + 16 + 10 + 19 = 75
In 2011 = 17 + 12 + 15 + 16 + 30 = 90
In 2012 = 21 + 12 + 13 + 20 + 14 = 80
In 2013 = 6 + 14 + 8 + 31 + 27 =86
Total Average=(74+71+75+90+80+86)/6 =476/6≈80(79.33)
