Highest annual growth rate in production is recorded in
Solution
The Growth rate of Iron Ore in 2008 = $$\dfrac{131-102}{102} \approx 30\%$$ The Growth rate of Gold in 2011 = $$\dfrac{25-20}{20} = 25\%$$ The Growth rate of Aluminium in 2008 = $$\dfrac{98-81}{81} \approx 21\%$$ The Growth rate of Iron Ore in 2008 = $$\dfrac{18-15}{15} = 20\%$$ Hence, Highest annual growth rate in production is recorded in Iron Ore in 2008. Hence, option A is the correct answer.
