Business Arithmetic Class 12 Notes PDF
Business Arithmetic explains how entrepreneurs use numbers to control pricing, cash, inventory and returns. The chapter is formula-heavy, so students should revise definitions and calculation steps together.
Break-even, working capital and EOQ are the three calculation areas students should practise first.
Unit Price, Unit Cost and Gross Margin
Unit of sale is the basic management unit used for comparison. In a grocery store it can be a customer. In a restaurant it can be a diner.
| Formula | Use |
|---|---|
| Unit Price = Total Billed Amount / Number of Customers | Finds average customer value |
| Unit Cost = Total Variable Cost / Units Sold | Finds average cost per unit |
| Gross Margin = Unit Price - Unit Cost | Shows contribution before fixed expenses |
Break-Even Analysis for Multiple Products
For many products, NCERT uses weighted average contribution margin. Students must multiply each product contribution by its sales mix percentage.
Cash Flow Projection and Budgets
A cash flow projection looks forward, while a cash flow statement records the past. Budgets convert plans into numbers for sales, production, capital, cash flow, marketing and projects.
Working Capital, Inventory Control and EOQ
Working capital funds daily operations. Inventory control uses SKU codes, ABC analysis and EOQ to keep stock available at the lowest practical cost.
