Price Calculation for Chocolates: A Simple Guide

Introduction

When dealing with price calculations involving different units of weight, it is essential to understand the relationship between kilograms (kg) and grams (g). This guide will help you determine the cost of 250 grams of chocolates when 1 kg of chocolates is priced at 20 rupees. By applying simple arithmetic and understanding the conversion between kg and g, you can easily calculate the price for any given weight.

Step-by-Step Calculation

Let's begin with the given information: 1 kg of chocolate 20 rupees 1 kg 1000 g These are fundamental units that allow us to convert between masses seamlessly.

Understanding the Units

The base unit of weight in the metric system is the kilogram (kg). More commonly, in every day usage, smaller units such as grams (g) are used. So, it is important to know that 1 kilogram is equivalent to 1000 grams. This relationship is crucial for breaking down larger quantities into smaller, manageable units.

Converting Weight to Price

Now, let's tackle the specific problem presented. If 1 kg of chocolates costs 20 rupees, we need to find out how much 250 grams of chocolates would cost.

Convert Grams to Kilograms

To do this, we first convert the given weight from grams to kilograms. We know that:
1 kg 1000 g
Therefore:
250 g 250 / 1000 0.25 kg

Calculate the Cost in Rupees

Given that 1 kg of chocolates costs 20 rupees, we can now calculate the cost for 0.25 kg:
20 rupees / 1 kg x rupees / 0.25 kg
Solving for x:
x 20 * 0.25 5 rupees

Ensuring Accuracy

It is always a good practice to double-check your calculations. We can also verify this by breaking down the calculation another way. Since 250 grams is 1/4 of 1000 grams, the price for 250 grams should be 1/4 of the price for 1000 grams:
20 rupees / 1000 g 5 rupees / 250 g

Conclusion

In summary, we can easily determine the price of 250 grams of chocolates when 1 kg costs 20 rupees. By converting grams to kilograms and applying simple arithmetic, we find that 250 grams of chocolates cost 5 rupees. This method can be applied to any quantity of chocolates, making it a useful skill for budgeting and comparison shopping. Understanding these basic calculations can save you time and money in your everyday purchases.
