Explanation:

GIVEN : Working Capital Rs 3,20,000; Current Liabilities Rs 1,40,000; Fixed Assets Rs 2,60,000; Debentures Rs 2,10,000; Long Term Bank Debt Rs 78,000.

CURRENT ASSETS = WORKING CAPITAL + CURRENT LIABILITIES

                                  =  Rs 3,20,000 + Rs 1,40,000

                                  = Rs. 4,60,000

TOTAL ASSETS= CURRENT ASSETS + FIXED ASSETS 

                           = Rs. 4,60,000 + Rs. 2,60,000

                           = Rs. 7,20,000

TOTAL DEBTS = Debentures + Long Term Bank Debt 

                          =  Rs 2,10,000 + Rs 78,000

                          = Rs. 2,88,000

TOTAL DEBTS TO ASSETS RATIO = TOTAL DEBTS / TOTAL ASSETS * 100

                                                           = Rs. 2,88,000 / Rs. 7,20,000 * 100

                                                           = 40% (ANSWER)
