Calculate Debt equity Ratio :

13% Debentures ₹ 6,00,000
Shareholders fund ₹ 8,00,000
Net Profit before tax ₹ 3,51,000
Current Liabilities ₹ 1,60,000

0.75 : 1

The correct answer is Option (2) - 0.75 : 1.

Debt = 13% debentures
        = 6,00,000
Equity = shareholders funds
          = 8,00,000

Debt-equity ratio = Debt/Equity
                           = 6,00,000/8,00,000
                           = 0.75 :1

*NOTE- PROFIT IS ALREADY INCLUDED IN SHAREHOLDERS FUNDS AS (SHAREHOLDER FUNDS = SHARE CAPITAL + RESERVES & SURPLUS + MONEY RECEIVED AGAINST SHARE WARRANTS).
