Calculate the Current Ratio, Quick Ratio, Net Profit Margin, and Return on Total Assets.

$$\text{Current Ratio} = \frac{\text{Rs. } 8,00,000}{\text{Rs. } 4,00,000}$$ $$\text{Current Ratio} = 2.00$$

The Current Ratio is $\boxed{2.00}$.

$$\text{Quick Ratio} = \frac{\text{Rs. } 8,00,000 - \text{Rs. } 2,00,000}{\text{Rs. } 4,00,000}$$ $$\text{Quick Ratio} = \frac{\text{Rs. } 6,00,000}{\text{Rs. } 4,00,000}$$ $$\text{Quick Ratio} = 1.50$$

The Quick Ratio is $\boxed{1.50}$.

$$\text{Net Profit Margin} = \frac{\text{Rs. } 2,40,000}{\text{Rs. } 20,00,000} \times 100\%$$ $$\text{Net Profit Margin} = 0.12 \times 100\%$$ $$\text{Net Profit Margin} = 12\%$$

The Net Profit Margin is $\boxed{12\%}$.

$$\text{Return on Total Assets} = \frac{\text{Rs. } 2,40,000}{\text{Rs. } 16,00,000} \times 100\%$$ $$\text{Return on Total Assets} = 0.15 \times 100\%$$ $$\text{Return on Total Assets} = 15\%$$

The Return on Total Assets is $\boxed{15\%}$.

$$\text{Debt-to-Equity Ratio} = \frac{\text{Rs. } 6,00,000}{\text{Rs. } 10,00,000}$$ $$\text{Debt-to-Equity Ratio} = 0.60$$

The Debt-to-Equity Ratio is $\boxed{0.60}$.

$$\text{Return on Equity} = \frac{\text{Rs. } 2,40,000}{\text{Rs. } 10,00,000} \times 100\%$$ $$\text{Return on Equity} = 0.24 \times 100\%$$ $$\text{Return on Equity} = 24\%$$

The Return on Equity is $\boxed{24\%}$.
