Business Arithmetic Chapter Overview
Chapter 5 is the main numerical chapter in Class 12 Entrepreneurship. NCERT connects simple arithmetic with actual business decisions. The chapter trains students to calculate costs, contribution, break-even point, working capital need, inventory level and return on investment. The answer is not complete until the number is linked back to the business decision.
- Break-even analysis shows the sales level at which profit is zero.
- Working capital checks whether day-to-day business operations have enough funds.
- Inventory control helps avoid excess stock and stock shortage.
- ROI and ROE compare business returns with investment and owner equity.
Business Arithmetic Formulas Covered
The official PDF should be read with a formula notebook. Write the formula first, substitute values in the second line, show calculation in the third line, and then write a short interpretation. This keeps board answers neat and reduces avoidable arithmetic mistakes.

How to Use This Book PDF
Start with the formula list before solving examples. For each numerical, underline what is given, write the required value, and check whether the answer should be in units, rupees, percentage or times. Important: many marks are lost because students give the calculation but skip the business meaning of the result.
After solving a question, write one closing line such as the sales level is enough to cover all costs, or the business needs more working capital. That short interpretation makes the answer look complete to the examiner.
