From the given bar graph, for the year 2016:
* Revenue (Sales) of Company Z = ₹ $2057$ crores
* Profit of Company Z = ₹ $847$ crores

The formula for the profit percentage margin on revenue is:

$$\text{Profit Margin Percentage}=\left(\frac{\text{Profit}}{\text{Revenue (Sales)}}\times 100\right)\%$$

Substituting the values into the formula:

$$\text{Profit Margin Percentage}=\left(\frac{847}{2057}\times 100\right)\%$$

$$\Rightarrow \left(\frac{84700}{2057}\right)\%\approx 41.1764\%\approx 41.18\%$$
