Question

If the consumption of each petroleum product in 2011 is higher than that in 2010 then the minimum growth in total consumption in 2011 is more than:

• A. 20%
• B. 14.28%
• C. 16.66%
• D. cannot be determined

Answer 1

The correct option is A

20%

Here, Let total consumption of petroleum products in 2010 is x and in 2011 is y.
Now consider the component where the percentage change between the two years is maximum (this is Kerosene)
To compute minimum growth, 12x = 10y, so x = 10 and y = 12,

Growth = $\frac{y-x}{x}$ = 20%.
