Solution
1.Average sales = (25+45+38+52+47+55)/6 = 262/6 = 43.7 million tons
Therefore, required cost = Rs.(1.8 × 43700) lakhs = Rs.78600 lakhs (approx)

2.Total sales in year 2000 = (41 + 50 + 43 + 57 + 39 + 64) = 294 million tons
Total sales in year 2003 = (43 + 55 + 49 + 63 + 42 + 62) = 314 million tons
Required% = (294/314) × 100 = 93.63%

3.Total sales in 1998 = (25 + 45 + 38 + 52 + 47 + 55) = 262 million tons
Total sales in 2003 = 314 million tons
So, % increase = [(314 - 262)/262] × 100 = 20%

4.Average sales of state:
B = (45+39+50+48+53+55)/6 = 290/6 million tons
C = (38+40+43+43+46+49)/6 = 259/6 million tons
Required ratio = 290/6 : 259/6 = 290 : 260 = 29 : 26 (approx)

5.% decrease in 1999 = [(47 - 46)/47] × 100 = 2.12
% decrease in 2000 = [(46 - 39)/46] × 100 = 15.22
% decrease in 2001 = [(39 - 32)/39] × 100 = 17.9%
% decrease in 2002 = [(37 - 32)/32] × 100 = 15.625
% decrease in 2003 = [(42 - 37)/37] × 100 = 13.51
Hence, the percentage decrease was maximum in the year 2001

6.Required ratio = 3/4 × 2.27 : 3/10 × 1.25 = 227 : 50

7.Required% = (1.08/3.14) × 100 = 34% (approx)

8.Total number of candidates appearing from all the cities together
= (1.25 + 3.14 + 1.08 + 2.27 + 1.85 + 2.73) lakhs = 12.32 lakhs
Number of candidates passing from City F = 7/12 × 2.73 = 1.5925 lakh
Required% = (1.5925/12.32) × 100 = 12.93%

9.Number of failures:
City A = 3/10 × 1.25 = 0.375 lakh
City B = 3/8 × 3.14 = 1.1775 lakh
City C = 5/9 × 1.08 = 0.6 lakh
City D = 3/4 × 2.27 = 1.7025 lakh
City E = 2/5 × 1.85 = 0.74 lakh
City F = 5/12 × 2.73 = 0.455 lakh

10.Number of passed students from City E = 3/5 × 1.85 = 111000
