If volatility of a variable during 2000-2010 is defined as $$\frac{Maximum Value - Minimum Value}{Average Value}$$, then which of the following is TRUE ?

Let's calculate No of Units as Revenue / Unit price.

Per Unit cost as (Revenue - Profit ) / No of Units.

In that way, we calculate the table as follows.

Let's solve the options one by one,

Option A : Volatility for price per unit : 14-8/11.45 = 0.524

Option B :Volatility for Cost per unit : 13-5/8.91 = 0.898

Option C:Volatility for Total profit : 400-0/154.54 = 2.588

Option D:Volatility for Revenue = 1400-200/809.1 = 1.48

Among the above values ,volatility for total profit is the highest .

Hence C is the correct answer.
