Chapter 13 is the numerical heavyweight of the Analysis of Financial Statements book. It teaches you how to express the arithmetical relationship between two related items in the financial statements — and how to interpret those relationships to judge the firm's liquidity, solvency, efficiency and profitability. Ratios are not new figures; they are a compass that translates the numbers in the Balance Sheet and Statement of Profit & Loss into actionable signals about the business.
The chapter follows the standard four-fold functional classification: Liquidity Ratios (Current Ratio with the 2:1 benchmark, Quick / Acid-Test Ratio with 1:1), Solvency Ratios (Debt-Equity, Total Assets to Debt, Proprietary Ratio, Interest Coverage Ratio), Activity / Turnover Ratios (Inventory Turnover, Trade Receivables Turnover with its companion Average Collection Period, Trade Payables Turnover, Working Capital Turnover), and Profitability Ratios (Gross Profit Ratio, Operating Ratio with the 100 − rule for Operating Profit Ratio, Net Profit Ratio, and Return on Investment / Capital Employed).
The hard part is composition discipline: knowing exactly what goes into each numerator and denominator. Liquid Assets = Current Assets − Inventory − Prepaid Expenses. Long-term Debt EXCLUDES current liabilities. EBIT = PAT + Tax + Interest. Capital Employed = Shareholders' Funds + Long-term Borrowings. Operating Expenses EXCLUDE finance costs and non-operating items like loss-by-fire. The 75 MCQs in this set drill these definitions, then push you through every standard calculation pattern — including reverse-engineered numericals where the ratio is given and you must back-solve a missing figure.
