Understanding Rice Cost Calculation

When it comes to shopping for essential items like rice, one of the key skills to master is understanding cost calculations. This article will demonstrate how to determine the cost of a specific quantity of rice, based on the cost of a larger, known quantity. We will use a step-by-step method to find the price of 14 kilograms of rice, given that 25 kilograms of rice costs Rs. 1125.

Step-by-Step Calculation of Rice Cost

Let's break down the process into a series of simple steps:

First, identify the given quantity and its cost. Then, calculate the cost per kilogram. Finally, multiply the unit price by the desired quantity.

Given Information

Given that 25 kilograms of rice costs Rs. 1125, we need to find the cost of 14 kilograms.

Step 1: Calculate the Cost per Kilogram

To find the cost per kilogram, we divide the total cost by the total quantity:

$ cost_per_kg frac{Rs. 1125}{25 kg}$

Step 2: Calculate the Cost for 14 Kilograms

Now that we have the cost per kilogram, we can multiply it by the desired quantity (14 kg) to find the total cost:

$ cost_of_14_kg cost_per_kg times 14 kg$

Real Steps:

$ cost_per_kg frac{1125}{25} Rs. 45$ (cost per kg) $ cost_of_14_kg 45 times 14 Rs. 630$ (cost of 14 kg)

Conclusion

Therefore, the cost of 14 kilograms of rice, when 25 kg costs Rs. 1125, is Rs. 630.

This method can be applied to calculate the cost of any quantity of a product, given the cost of a different, known quantity. It is a fundamental skill in budgeting, shopping, and business.
