The correct option is
C 0.556
Long-term debt = Total external liabilities - current liabilities
= Rs. 5,00,000 - Rs. 1,00,000
= Rs. 4,00,000
Total non-fictitious assets = Total assets - Fictitious assets
= Rs. 10,10,000 - Rs. 10,000
= Rs. 10,00,000
Shareholders funds = Non-fictitious total assets - Total liabilities
= Rs. 10,00,000 - Rs. 5,00,000
= Rs. 5,00,000
Net assets = Total non-fictitious assets - Current liabilities
= Rs. 10,00,000 - Rs. 1,00,000
= Rs. 9,00,000
Proprietary ratio = Shareholders funds/ Capital employed
= Rs. 5,00,000/Rs. 9,00,000
= 0.556
