How Much Will 750 ML of Milk Cost?

Understanding the cost of milk is essential for budgeting and making informed purchasing decisions. This article will guide you through the process of calculating the cost of 750 ml of milk based on a given price for 500 ml.

Step-by-Step Calculation

The problem at hand is straightforward: if 500 ml of milk is priced at 20 rupees, how much will 750 ml of milk cost? To solve this, we first need to determine the cost per milliliter.

Cost Per Milliliter

Let's start with the given price and volume:

Given:

500 ml of milk costs 20 rupees.

To find the cost per milliliter:

Determine the cost per milliliter: Calculate as follows:

Cost per ml frac{20 text{ rupees}}{500 text{ ml}} 0.04 text{ rupees/ml}

Cost for 750 ML

With the cost per milliliter established, we can now determine the cost for 750 ml:

Cost for 750 ml 750 ml times 0.04 text{ rupees/ml} 30 text{ rupees}

Therefore, 750 ml of milk will cost 30 rupees.

Alternative Calculation

To verify our original solution, we can use an alternative method:

Calculate the cost per ml using the original price and volume: 750 ml / 500 ml 1.5 (This means 1.5 times the cost of 500 ml) Multiply the original price by 1.5: 20 rupees times 1.5 30 rupees

As a result, the cost of 750 ml of milk is 30 rupees.

Conclusion

By understanding basic mathematical calculations, you can easily determine the cost of any volume of milk given its price per a specific quantity. The cost of 750 ml of milk, when 500 ml costs 20 rupees, is indeed 30 rupees. This knowledge not only helps in making informed decisions but also ensures that you are not overcharged when purchasing milk.
