From the following information, calculate the 'Proprietary Ratio':
The Proprietary Ratio is calculated as:
\[ \text{Proprietary Ratio} = \frac{\text{Total Equity}}{\text{Total Assets}} = \frac{\text{Share Capital} + \text{Reserves and Surplus}}{\text{Total Liabilities} + \text{Total Assets}} \]
Here, Total Equity = ₹ 4,00,000 + ₹ 3,00,000 = ₹ 7,00,000
Total Liabilities = ₹ 3,50,000 + ₹ 1,50,000 + ₹ 5,00,000 = ₹ 10,00,000
The ratio is:
\[ \text{Proprietary Ratio} = \frac{7,00,000}{10,00,000} = 0.70 \]
(a) State the following:
(i) Kohlrausch law of independent migration of ions
A solution of glucose (molar mass = 180 g mol\(^{-1}\)) in water has a boiling point of 100.20°C. Calculate the freezing point of the same solution. Molal constants for water \(K_f\) and \(K_b\) are 1.86 K kg mol\(^{-1}\) and 0.512 K kg mol\(^{-1}\) respectively.
Write the reactions involved when D-glucose is treated with the following reagents: (a) HCN (b) Br\(_2\) water
Identify A and B in each of the following reaction sequence:
(a) \[ CH_3CH_2Cl \xrightarrow{NaCN} A \xrightarrow{H_2/Ni} B \]
(b) \[ C_6H_5NH_2 \xrightarrow{NaNO_2/HCl} A \xrightarrow{C_6H_5NH_2} B \]
