Trade payables turnover ratio = \(\frac { Net\quad credit\quad purchases }{ Average\quad trade\quad payables } \)
Average trade payables = \(\frac { Opening\quad trade\quad payables+Closing\quad trade\quad payables }{ 2 } \)
= \(\frac { (20,000+4,000)+(10,000+6,000) }{ 2 } \)
= \(\frac { 40,000 }{ 2 } \) = Rs.20,000
Average payment period (in days) = \(\frac { Number\quad of\quad days\quad in\quad a\quad year }{ Trade\quad payables\quad turn\quad over\quad ratio } \)
=\(\frac { 365 }{ 5 } \)  = 70 days
∴ Trade payables turnover ratio (in days) = \(\frac { 1,00,000 }{ 20,000 } \) = 5 times.

(i) Debt equity ratio = \(\frac { Long\quad term\quad debt }{ Shareholders\quad funds } \)
Long term debt = 9% Debentures = Rs.8,00,000
Shareholder's funds =Equity share capital + Preference share capital + Reserves and surplus
= 3,00,000 + 4,00,000 + 3,00,000 = Rs.10,00,000
∴ Debt equity ratio =  \(\frac { 8,00,000 }{ 10,00,000 } \)= 0.8:1
(ii) Proprietary ratio = \(\frac { Shareholder's\quad funds }{ Total\quad assets } \)
= \(\frac { 10,00,000 }{ 20,00,000 } \)= 0.5:1
(iii) Capital gearing ratio = \(\frac { Funds\quad bearing\quad fixed\quad interest\quad or\quad fixed\quad dividend }{ Equity\quad Shareholder's\quad funds } \)
Funds bearing fixed interest or fixed dividend  = 8% Preference capital + 9% Debentures
= Rs.4,00,000+8,00,000
= Rs.12,00,000
Equity shareholder's funds = Equity share capital + Reserve and Surplus
= 3,00,000 + 5,00,000
= Rs.6,00,000
∴ Capital gearing ratio = \(\frac { 12,00,000 }{ 6,00,000 } \).

Quick ratio = \(\frac { Quick\quad assets }{ Current\quad liabilities } \)
Quick assets = Current assets - Inventories - Prepaid expenses
= Rs.4,00,000 + Rs.70,000 - Rs.30,000 = Rs.3,00,000
∴ Quick ratio = \(\frac { 3,00,000 }{ 2,00,000 } \) = 1.5:1

(i) Gross profit ratio =\(\frac { Gross\quad profit }{ Revenue\quad from\quad operations } \) \(\times\) 100
Cost of revenue from operations = Purchases of stock-in-trade + Change in inventory + Direct expenses
= 8,500 - 500 + 0 = Rs.8,000
Gross profit = Revenue from operations - Cost of revenue from operations
= 10,000 - 8,000 = Rs.2,000
∴ Gross profit ratio =\(\frac { 2,000 }{ 8,000 } \) \(\times\) 100 = 25%
(ii) Net profit ratio =\(\frac { Net\quad profit\quad after\quad tax }{ Revenue\quad from\quad operations } \) \(\times\) 100
=\(\frac { 800 }{ 10,000 } \) \(\times\) 100 = 8%
(iii) Operating cost ratio =\(\\ \frac { Operating\quad cost }{ Revenue\quad from\quad operations } \) \(\times\) 100
Operating cost = Cost of revenue from operations + Operating expenses
Operating expenses Other expenses = Rs.1,200
Operating cost = 8,000 + 1,200 = Rs.9,200
∴ Operating cost ratio =\(\frac { 9,200 }{ 10,000 } \) \(\times\) 100 = 92%
(iv) Operating profit ratio = \(\frac { Operating\quad profit }{ Revenue\quad from\quad operations } \) \(\times\) 100
Operating profit = Revenue from operations - Operating Cost
= 10,000 - 9,200 = Rs.800
∴ Operating profit ratio = \(\frac { 800 }{ 10,000 } \) \(\times\) 100 = 8%

Current ratio = \(\frac { Current\ assets }{ Current\ liabilities } \)
Current assets Current investments + Inventories + Trade receivables + Cash and cash equivalents + Prepaid expenses
= 15,000 + 29,000 + 5,000 + 5,000 + 0
= Rs.54,000
Current liabilities = Trade creditors + Bills payable + Expenses payable
= 36,000 + 10,000 + 8,000 = Rs.54,000
∴ Current assets = \(\frac { 54,000 }{ 54,000 } \) = 1 : 1
