In short: Ratio Analysis and Cash Flow Statement form Part B of CBSE Class 12 Accountancy, carrying 20 marks out of 80. These two chapters are the most feared in the entire syllabus — not because they are hard, but because students approach them without a system. This guide gives you every ratio formula in one table, the complete Cash Flow Statement structure with adjustments, worked examples, and the exact common errors that cost marks every year. Follow the steps, and Part B becomes the easiest 20 marks on the paper.
Why Part B Is Actually the Easiest Section to Score
Part B carries 20 marks — one-quarter of the Accountancy paper. Most students spend 80% of their preparation time on Part A (Partnership + Company Accounts) and treat Part B as an afterthought. That is a mistake.
Here is why Part B is more scoring than Part A:
| Factor | Part A (60 marks) | Part B (20 marks) |
|---|---|---|
| Question types | Multi-step numericals | Formula-based calculations |
| Error propagation | One wrong step ruins the answer | Each ratio is independent |
| Time needed | 8-mark problems take 15–20 min | Full Part B doable in 40 min |
| Predictability | Problem variations are wide | Same formulas, same format every year |
If you know the formulas and the Cash Flow Statement format, Part B is essentially free marks. Check the complete chapter-wise marks weightage to see exactly how these 20 marks fit into the bigger picture.
All Ratio Formulas in One Table
CBSE asks ratios from five categories. Memorise this table — it covers every ratio the board can ask.
Liquidity Ratios
| Ratio | Formula | Ideal | What It Measures |
|---|---|---|---|
| Current Ratio | Current Assets ÷ Current Liabilities | 2:1 | Short-term debt-paying ability |
| Quick Ratio (Liquid Ratio) | Quick Assets ÷ Current Liabilities | 1:1 | Immediate debt-paying ability |
Quick Assets = Current Assets – Inventory – Prepaid Expenses
Current Assets include: Cash, Bank, Debtors (Sundry/Trade Receivables), Bills Receivable, Short-term Investments, Inventory, Prepaid Expenses
Current Liabilities include: Creditors (Trade Payables), Bills Payable, Outstanding Expenses, Bank Overdraft, Short-term Loans, Provision for Tax (if due within 12 months)
Solvency Ratios
| Ratio | Formula | Ideal | What It Measures |
|---|---|---|---|
| Debt-Equity Ratio | Long-term Debt ÷ Shareholders' Funds | 2:1 | Long-term financial risk |
| Total Assets to Debt Ratio | Total Assets ÷ Long-term Debts | — | Asset coverage for debt |
| Proprietary Ratio | Shareholders' Funds ÷ Total Assets | — | Owner stake in total assets |
| Interest Coverage Ratio | Net Profit before Interest and Tax ÷ Interest on Long-term Debt | — | Ability to service debt |
Shareholders' Funds = Share Capital + Reserves and Surplus – Fictitious Assets (Preliminary Expenses, Discount on Issue of Shares, etc.)
Long-term Debt = Debentures + Long-term Loans (not Bank Overdraft — that is current)
Activity (Turnover) Ratios
| Ratio | Formula | What It Measures |
|---|---|---|
| Inventory Turnover Ratio | Net Sales ÷ Average Inventory | How fast stock sells |
| Trade Receivables Turnover | Net Credit Sales ÷ Average Trade Receivables | How fast debtors pay |
| Trade Payables Turnover | Net Credit Purchases ÷ Average Trade Payables | How fast you pay creditors |
| Working Capital Turnover | Net Sales ÷ Working Capital | Efficiency of working capital use |
Average Inventory = (Opening Inventory + Closing Inventory) ÷ 2
Working Capital = Current Assets – Current Liabilities
Profitability Ratios
| Ratio | Formula | What It Measures |
|---|---|---|
| Gross Profit Ratio | (Gross Profit ÷ Net Sales) × 100 | Profit after production costs |
| Operating Ratio | (Operating Cost ÷ Net Sales) × 100 | Total operational efficiency |
| Operating Profit Ratio | (Operating Profit ÷ Net Sales) × 100 | Core business profitability |
| Net Profit Ratio | (Net Profit ÷ Net Sales) × 100 | Overall profit per rupee of sales |
| Return on Investment (ROI) | (Net Profit before Interest and Tax ÷ Capital Employed) × 100 | Return earned on total capital |
Operating Cost = Cost of Goods Sold + Operating Expenses (Office + Selling expenses)
Operating Profit = Net Sales – Operating Cost (excludes non-operating income/expenses)
Capital Employed = Shareholders' Funds + Long-term Debt OR Total Assets – Current Liabilities – Fictitious Assets
Earning Ratios
| Ratio | Formula | What It Measures |
|---|---|---|
| Earnings Per Share (EPS) | Net Profit after Tax ÷ Number of Equity Shares | Per-share earning |
| Price-Earnings Ratio (P/E) | Market Price per Share ÷ EPS | Market confidence indicator |
Step-by-Step: How to Solve Ratio Problems
Step 1: Read the question and identify which ratio is asked.
Step 2: Write the formula immediately (this alone earns 1 mark in most CBSE papers).
Step 3: Extract the required numbers from the given data. Be careful about:
- Whether Bank Overdraft is given (it is a current liability, not long-term debt)
- Whether Preliminary Expenses or Discount on Issue is given (deduct from Shareholders' Funds)
- Whether Opening and Closing figures are given (you may need averages)
Step 4: Substitute and calculate. Show the division clearly.
Step 5: Express the answer in the correct format — ratios as X:1, percentages with %, and interpret if asked.
Worked Example 1: Liquidity Ratios
Given: Current Assets ₹4,00,000 (including Inventory ₹1,20,000 and Prepaid Expenses ₹10,000). Current Liabilities ₹2,00,000.
Current Ratio = 4,00,000 ÷ 2,00,000 = 2:1 ✓
Quick Assets = 4,00,000 – 1,20,000 – 10,000 = ₹2,70,000
Quick Ratio = 2,70,000 ÷ 2,00,000 = 1.35:1 ✓
Worked Example 2: Debt-Equity and ROI
Given: Share Capital ₹5,00,000. Reserves ₹2,00,000. 10% Debentures ₹3,00,000. Net Profit before tax and interest ₹1,40,000. Tax rate 30%.
Shareholders' Funds = 5,00,000 + 2,00,000 = ₹7,00,000
Debt-Equity Ratio = 3,00,000 ÷ 7,00,000 = 0.43:1
Capital Employed = 7,00,000 + 3,00,000 = ₹10,00,000
ROI = (1,40,000 ÷ 10,00,000) × 100 = 14%

Cash Flow Statement — The Complete Structure
A Cash Flow Statement shows how cash moved during the year, classified into three activities. CBSE follows AS-3 (Revised) format.
The Three Activities
| Activity | What It Covers | Cash Inflow Examples | Cash Outflow Examples |
|---|---|---|---|
| Operating | Day-to-day business | Cash from customers, interest received | Cash paid to suppliers, employees, taxes |
| Investing | Long-term assets | Sale of machinery, sale of investments | Purchase of machinery, purchase of investments |
| Financing | Capital structure | Issue of shares/debentures, borrowing | Dividend paid, redemption of debentures, loan repayment |
Step-by-Step: Cash Flow from Operating Activities (Indirect Method)
This is the section students struggle with most. Follow these steps exactly:
Step 1: Start with Net Profit before Tax and Extraordinary Items
Step 2: Add back non-cash and non-operating items
| Add Back | Reason |
|---|---|
| Depreciation | Non-cash expense |
| Goodwill written off / Amortisation | Non-cash expense |
| Loss on sale of fixed assets | Non-operating (goes to Investing) |
| Discount on issue of shares/debentures written off | Non-cash |
| Interest on debentures/loans (if classified as financing) | Goes to Financing |
| Premium on redemption of debentures written off | Non-cash |
Step 3: Deduct non-operating income items
| Deduct | Reason |
|---|---|
| Profit on sale of fixed assets | Non-operating (goes to Investing) |
| Interest received / Dividend received | Goes to Investing |
| Profit on sale of investments | Goes to Investing |
Step 4: Adjust for changes in Working Capital
| Change | Effect on Cash |
|---|---|
| Increase in Current Assets (Debtors, Inventory, etc.) | Deduct (cash used) |
| Decrease in Current Assets | Add (cash released) |
| Increase in Current Liabilities (Creditors, etc.) | Add (cash saved) |
| Decrease in Current Liabilities | Deduct (cash paid) |
Step 5: Deduct Tax Paid
Result = Cash Flow from Operating Activities
Worked Example: Cash Flow from Operating Activities
Given: Net Profit before tax ₹2,50,000. Depreciation ₹40,000. Loss on sale of machinery ₹8,000. Interest on debentures ₹15,000. Increase in debtors ₹20,000. Decrease in inventory ₹12,000. Increase in creditors ₹18,000. Tax paid ₹60,000.
| Particulars | Amount (₹) |
|---|---|
| Net Profit before Tax | 2,50,000 |
| Add: Depreciation | 40,000 |
| Add: Loss on sale of machinery | 8,000 |
| Add: Interest on debentures | 15,000 |
| Operating profit before working capital changes | 3,13,000 |
| Less: Increase in Debtors | (20,000) |
| Add: Decrease in Inventory | 12,000 |
| Add: Increase in Creditors | 18,000 |
| Cash generated from operations | 3,23,000 |
| Less: Tax Paid | (60,000) |
| Cash Flow from Operating Activities | 2,63,000 |
Cash Flow from Investing Activities
List each investing transaction separately:
| Transaction | Treatment |
|---|---|
| Purchase of fixed assets | Outflow (negative) |
| Sale of fixed assets | Inflow (use actual sale proceeds, not book value) |
| Purchase of investments | Outflow |
| Sale of investments | Inflow |
| Interest received | Inflow |
| Dividend received | Inflow |
Calculating sale proceeds when not directly given:
Sale Proceeds = Book Value ± Profit or Loss on Sale
Book Value = Cost – Accumulated Depreciation
Cash Flow from Financing Activities
| Transaction | Treatment |
|---|---|
| Issue of shares | Inflow |
| Issue of debentures | Inflow |
| Long-term borrowing | Inflow |
| Redemption of debentures | Outflow |
| Repayment of loans | Outflow |
| Dividend paid | Outflow |
| Interest paid on debentures/loans | Outflow |
Final step: Add all three activities + Opening Cash and Cash Equivalents = Closing Cash and Cash Equivalents. This must match the Balance Sheet figure.

Common Errors That Cost Marks
Ratio Analysis Errors
Error 1: Including Bank Overdraft in long-term debt. Bank Overdraft is a current liability, not long-term debt. Including it in Debt-Equity Ratio inflates the ratio incorrectly. CBSE examiners specifically check for this.
Error 2: Forgetting to deduct Fictitious Assets from Shareholders' Funds. If Preliminary Expenses or Discount on Issue of Shares/Debentures appears in the Balance Sheet, deduct it from Shareholders' Funds before calculating Debt-Equity Ratio or Proprietary Ratio.
Error 3: Using Net Sales vs Gross Sales incorrectly. All profitability ratios use Net Sales (after sales returns). If the question gives Gross Sales and Sales Returns separately, calculate Net Sales first.
Error 4: Confusing Operating Profit with Net Profit. Operating Profit = Revenue from Operations – Operating Cost. It excludes non-operating income (rent received, interest on investments) and non-operating expenses (interest on debentures, loss on sale of assets). Net Profit includes everything.
Cash Flow Statement Errors
Error 5: Double-counting depreciation. You add depreciation to Net Profit (to reverse the non-cash charge), but you must NOT also show it as an investing outflow. Depreciation is not a cash flow — it only appears as an add-back in the Operating section.
Error 6: Using book value instead of sale proceeds for asset sales. When machinery is sold, the cash inflow in the Investing section is the actual sale proceeds (Book Value ± Profit/Loss), not the book value alone.
Error 7: Forgetting to adjust for Proposed Dividend. If a Proposed Dividend appears in the previous year's Balance Sheet but not in the current year's, it was likely paid during the year. Show it as a financing outflow. If it appears in the current year's Balance Sheet, it has not been paid yet — do not include it as an outflow.
Error 8: Missing the working capital adjustment direction. Remember: Increase in Current Assets = cash went out (deduct). Increase in Current Liabilities = cash saved (add). Students mix this up under exam pressure. Write the rule at the top of your answer sheet.
Practice Problems
Problem 1: Ratio Analysis (6 marks)
From the following information, calculate: (a) Current Ratio, (b) Quick Ratio, (c) Debt-Equity Ratio, (d) Gross Profit Ratio, (e) Net Profit Ratio, (f) ROI.
Data: Total Revenue from Operations ₹10,00,000. Cost of Goods Sold ₹6,00,000. Operating Expenses ₹1,50,000. Interest on Debentures ₹30,000. Tax ₹50,000. Current Assets ₹3,00,000 (Inventory ₹80,000). Current Liabilities ₹1,50,000. 10% Debentures ₹2,00,000. Share Capital ₹4,00,000. Reserves ₹1,50,000.
Solution:
(a) Current Ratio = 3,00,000 ÷ 1,50,000 = 2:1
(b) Quick Ratio = (3,00,000 – 80,000) ÷ 1,50,000 = 2,20,000 ÷ 1,50,000 = 1.47:1
(c) Shareholders' Funds = 4,00,000 + 1,50,000 = 5,50,000. Debt-Equity = 2,00,000 ÷ 5,50,000 = 0.36:1
(d) Gross Profit = 10,00,000 – 6,00,000 = 4,00,000. Gross Profit Ratio = (4,00,000 ÷ 10,00,000) × 100 = 40%
(e) Net Profit = 10,00,000 – 6,00,000 – 1,50,000 – 30,000 – 50,000 = 2,70,000. Net Profit Ratio = (2,70,000 ÷ 10,00,000) × 100 = 27%
(f) Capital Employed = 5,50,000 + 2,00,000 = 7,50,000. Net Profit before interest and tax = 2,70,000 + 30,000 + 50,000 = 3,50,000. ROI = (3,50,000 ÷ 7,50,000) × 100 = 46.67%
Problem 2: Cash Flow Statement (8 marks)
Prepare a Cash Flow Statement from the following information:
Net Profit after tax ₹1,80,000. Tax paid ₹50,000. Depreciation ₹35,000. Profit on sale of investment ₹12,000. Interest on debentures ₹20,000. Increase in debtors ₹15,000. Increase in stock ₹10,000. Increase in creditors ₹8,000. Purchase of machinery ₹1,50,000. Sale of investment ₹60,000. Issue of equity shares ₹2,00,000. Dividend paid ₹40,000. Interest paid ₹20,000. Opening Cash ₹25,000.
Solution:
Cash Flow from Operating Activities:
| Particulars | ₹ |
|---|---|
| Net Profit after tax | 1,80,000 |
| Add: Tax paid (to arrive at profit before tax) | 50,000 |
| Net Profit before tax | 2,30,000 |
| Add: Depreciation | 35,000 |
| Add: Interest on debentures | 20,000 |
| Less: Profit on sale of investment | (12,000) |
| Operating profit before WC changes | 2,73,000 |
| Less: Increase in debtors | (15,000) |
| Less: Increase in stock | (10,000) |
| Add: Increase in creditors | 8,000 |
| Cash generated from operations | 2,56,000 |
| Less: Tax paid | (50,000) |
| Cash from Operating Activities | 2,06,000 |
Cash Flow from Investing Activities:
| Particulars | ₹ |
|---|---|
| Purchase of machinery | (1,50,000) |
| Sale of investment | 60,000 |
| Cash from Investing Activities | (90,000) |
Cash Flow from Financing Activities:
| Particulars | ₹ |
|---|---|
| Issue of equity shares | 2,00,000 |
| Dividend paid | (40,000) |
| Interest paid | (20,000) |
| Cash from Financing Activities | 1,40,000 |
Net Increase in Cash = 2,06,000 + (–90,000) + 1,40,000 = ₹2,56,000
Closing Cash = 25,000 + 2,56,000 = ₹2,81,000

Frequently Asked Questions
How many marks do Ratio Analysis and Cash Flow carry in CBSE 2027?
Part B (Analysis of Financial Statements) carries 20 marks out of 80 in the theory paper. Ratio Analysis typically carries 6–8 marks and Cash Flow Statement carries 8–12 marks. Together, they form one-quarter of your paper and are highly predictable in format.
Should I memorise all ratios or can I derive them?
Memorise them. While the formulas are logical, exam time pressure means you cannot afford to derive each ratio from scratch. The table in this guide contains every ratio CBSE can ask — memorise the formula, the ideal ratio (where applicable), and what it measures. Writing the formula itself earns 1 mark in most questions.
What is the most common Cash Flow mistake in board exams?
Double-counting items is the most common mistake. Students add depreciation in Operating Activities (correct) and then also deduct it as an investing outflow (incorrect). Depreciation is NOT a cash flow — it only appears as a non-cash adjustment. The second most common mistake is confusing which direction working capital adjustments go.
Does CBSE ask Cash Flow by Direct or Indirect Method?
CBSE asks the Indirect Method exclusively for Operating Activities. The Indirect Method starts with Net Profit and adjusts for non-cash items and working capital changes. You do not need to learn the Direct Method for CBSE board exams.
Can I attempt Part B before Part A in the exam?
Yes, and many toppers recommend it. Part B is formulaic and takes about 40 minutes. Completing it first builds confidence and ensures you do not run out of time for the easier section. Use the remaining 100 minutes for Part A. See our 3-hour exam strategy for detailed time splits.
Are comparative statements and common-size statements also important?
They carry 4–6 marks and occasionally appear as an alternative to ratio questions. Know the format for both Comparative Statement of Profit and Loss and Common Size Balance Sheet. They are straightforward — just calculations and percentages — so do not skip them.
