Calculating the cost of a large quantity of pens can be quite straightforward with a bit of arithmetic. In this detailed guide, we will walk through the process of determining the cost of 12 dozen pens, using a well-known example of 3 pens costing Rs. 20.

Understanding the Problem

Consider the scenario where we know the cost of 3 pens is Rs. 20. We need to find out how much 12 dozen pens would cost. Let's break it down step by step.

Step-by-Step Calculation

First, we need to understand that 12 dozen pens is equivalent to 144 pens (since 1 dozen equals 12 pens).

Cost of 3 pens: Rs. 20

Cost of 1 pen: Rs. 20 / 3 6.67

Rs. 6.67 * 144 Rs. 960

Alternative Methods to Find the Cost

Let's explore a few alternative methods to solve the same problem:

Direct Multiplication: Since 3 pens Rs. 20, 12 dozen (144 pens) would be calculated as follows:

12 dozen 144 pens 144 / 3 * 20 48 * 20 Rs. 960

Unit Cost Method: First, calculate the cost of one pen, then scale it up to 12 dozen pens.

Cost of 1 pen Rs. 20 / 3 ≈ Rs. 6.67

Cost of 12 dozen (144 pens) Rs. 6.67 * 144 Rs. 960

Cross-Multiplication Method: Utilize cross-multiplication to find the cost of 144 pens.

3 pens 20 Rs

144 pens (20 * 144) / 3 2880 / 3 Rs. 960

Breakdown by Dozen: Calculate the cost of one dozen pens first, then multiply by 12.

1 dozen 12 pens 20 / 3 Rs

12 dozen 12 * (20 / 3) 960 Rs
