\(\mathrm{Proprietary \,Ratio = \frac{Proprietor's \,Fund }{Total \,Assets}}\)
Total Assets = Debts × 2
= Rs. 5,00,000 × 2
= Rs. 10,00,000
Proprietor’s Funds = (Equity Share Capital) + (Preference Share Capital) + (Surplus)
= (5,00,000 × 0.5) + (5,00,000 × 0.5 × 25%) + (10,00,000 – 40% of 10,00,000)
= 2,50,000 + 62,500 + 6,00,000
= Rs. 9,12,500
Proprietary Ratio = \(\frac{9,12,500}{10,00,000}\)
= 0.912 : 1
