## The chapter "Production and Cost" in CBSE Class 12 Business Studies introduces students to the fundamental concepts of production, cost functions, and the relationship between them. Understanding these concepts is essential for analyzing how businesses operate and make decisions regarding resource allocation and cost management.

### Introduction to CBSE Class 12 Business Studies Chapter "Production and Cost"

This chapter covers various critical topics, including:

**Production Function**: It describes the relationship between inputs used in production and the resulting output. The production function can be expressed as $Q=f(L,K)$, where $Q$ is the total output, $L$ is labor, and $K$ is capital.**Total, Average, and Marginal Products**:**Total Product (TP)**: The total quantity of goods produced by a firm.**Average Product (AP)**: The total product divided by the number of units of a variable input.**Marginal Product (MP)**: The additional output produced by using one more unit of a variable input.

**Short Run and Long Run**:**Short Run**: A period during which at least one factor of production is fixed.**Long Run**: A period in which all factors of production can be varied.

**Law of Diminishing Marginal Product**: This law states that as more units of a variable input are added to fixed inputs, the additional output produced by each additional unit of the variable input eventually decreases.**Law of Variable Proportions**: It explains how output changes when only one input is increased while others are kept constant.**Returns to Scale**:**Increasing Returns to Scale**: When a proportional increase in all inputs leads to a more than proportional increase in output.**Constant Returns to Scale**: When a proportional increase in all inputs results in an equal proportional increase in output.**Decreasing Returns to Scale**: When a proportional increase in all inputs leads to a less than proportional increase in output.

**Cost Concepts**:**Total Cost (TC)**: The sum of total fixed cost (TFC) and total variable cost (TVC).**Average Cost (AC)**: Total cost divided by the number of units produced.**Marginal Cost (MC)**: The additional cost of producing one more unit of output.

**Cost Curves**:**Average Fixed Cost (AFC)**: TFC divided by the number of units produced.**Average Variable Cost (AVC)**: TVC divided by the number of units produced.**Short Run and Long Run Cost Curves**: Explaining their shapes and relationships.

## Questions and Answers for CBSE Class 12 Business Studies Chapter "Production and Cost"

**Q1: What is a production function?**

**ANS:**A production function shows the relationship between the inputs used in production and the resulting output. It indicates the maximum output that can be produced with given inputs.

**Q2: What are total, average, and marginal products?**

**ANS:****Total Product (TP):**The total quantity of goods produced.**Average Product (AP):**TP divided by the number of units of a variable input.**Marginal Product (MP):**The additional output produced by one more unit of a variable input.

**Q3: Differentiate between the short run and long run in production.**

**ANS:**In the short run, at least one factor of production is fixed, while in the long run, all factors of production can be varied.

**Q4: Explain the law of diminishing marginal product.**

**ANS:**As more units of a variable input are added to fixed inputs, the additional output produced by each additional unit eventually decreases.

**Q5: What is the law of variable proportions?**

**ANS:**It states that when one input is increased while keeping other inputs constant, there will be a point where the additional output per unit of the variable input will start to decrease.

**Q6: Describe increasing, constant, and decreasing returns to scale.**

**ANS:****Increasing Returns to Scale:**Output increases more than proportionally to inputs.**Constant Returns to Scale:**Output increases proportionally to inputs.**Decreasing Returns to Scale:**Output increases less than proportionally to inputs.

**Q7: What are total fixed cost, total variable cost, and total cost?**

**ANS:****Total Fixed Cost (TFC):**Costs that do not change with the level of output.**Total Variable Cost (TVC):**Costs that vary with the level of output.**Total Cost (TC):**The sum of TFC and TVC.

**Q8: Explain the shapes of short run cost curves.**

**ANS:**The short run cost curves (MC, AVC, AC) are typically U-shaped due to the law of variable proportions, which initially decreases and then increases marginal costs.
