Total 40 lakh tons.
Production in state A = 12 lakh tons.
State A % in total production = $\displaystyle \frac{12}{40} \times$ 100 = 30%.
2011 = Total production (I) = 40 lakh tons, State A = 12 lakh tons.
A % = $\displaystyle \frac{12}{40} \times$ 100 = 30%.
2012 Total production (I) = 45 lakh tons, State A = 14 lakh tons.
A % = $\displaystyle \frac{14}{45} \times$ 100 = 31.11%.
2013 Total production (I) = 52 lakh tons, State A = 16 lakh tons.
A % = $\displaystyle \frac{16}{52} \times$ 100 = 30.76%.
2014 Total production (I) = 54 lakh tons, State A = 18 lakh tons.
A % = $\bf {\displaystyle \frac{18}{54} \times}$ 100 = 33.33%.
Total (I) = 40 + 45 + 52 + 54 = 191 lakh tons.
By the Three states = 25 + 27 + 31.2 + 37.8 = 121 lakh tons.
Percentage = $\displaystyle \frac{121}{191} \times$ 100 = 63.35%.
Production in state C in 2013 = 6.2 lakh tons, in 2014 = 9.3 lakh tons.
By the Three states = 25 + 27 + 31.2 + 37.8 = 121 lakh tons.
Percentage = $\displaystyle \frac{9.3}{6.2} \times$ 100 = 150%.
Total production of the country in 2013 = 52 lakh tons.
By the three states = 16 + 9 + 6.2 = 31.2 lakh tons.
Production in remaining states = 52 – 31.2 = 20.8 lakh tons.
Ratio Three states: Remaining states => 31.2 : 20.8 = 3 : 2.
Income = 10.2 cr. Expenditure = 8 cr.
Profit = Income – Expenditure = 10.2 – 8 = 2.2 cr.
Profit % = $\displaystyle \frac{2.2}{8} \times $ 100 = 27.5%.
2010 = 10.2 – 8.00 = 2.2 cr.
2011 = 14.00 – 10.5 = 3.5 cr.
2012 = 15.00 – 12.00 = 3.00 cr.
2013 = 16.25 – 13.00 = 3.25 cr.
2014 = 17.00 – 13.6 = 3.4 cr.
2015 = 17.00 – 14.00 = 3 cr.
Average profit = $\displaystyle \frac{\text {Total profit}}{\text {Number of Years}}$
Total profit = 2.2 + 3.5 + 3.00 + 3.25 + 3.4 + 3.00 = 18.35 cr.
Average profit = $\displaystyle \frac{18.55}{6}$ = 3.058 cr.
In 3 years => 2010, 2012, 2015.
Income in 2010 = 10.2 cr; Income in 2015 = 17 cr.
Increase = 17 – 10.2 = 6.8 cr.
Increase % = $\displaystyle \frac{6.8}{10.2} \times$ 100 = 66.66%.
In 2012, 2013 and 2014 => 25%.
