6. 4
Avg = (25+19+27+22+30+21)/6 = 24 thousand
7. 3
Avg(2012) = (16+23+27+19+17+30)/6 = 132/6 = 22 thousand
Reqd% = 22/25*100 = 88%
8. 2
Total(2008) = 199 thousand
C(Total) = 140 thousand
Req% = 119/140 * 100 = 85%
9. 4
Avg(2013) = 141/6 = 23.5 thousand
Avg(2010)117/6 = 19.5 thousand
Difference = 4 thousand
100. 3
D(Total) = 119 thousand
