Calculating Cost: A Practical Example with Tomatoes and Potatoes
The problem of calculating the cost of goods is a common one in everyday life. For instance, you might find yourself in a situation where you need to determine the total cost of half a dozen tomatoes and four kilograms of potatoes. This article will guide you through a detailed method to solve such problems and understand the cost calculation process.
Understanding the Cost of 5 Tomatoes and 3 Kilograms of Potatoes
Let's start with the given information. If five tomatoes cost Rs 30 and three kilograms of potatoes cost Rs 120, we need to calculate the individual costs of a tomato and a kilogram of potatoes.
Calculating the Cost of One Tomato
To find the cost of one tomato:
Cost of 5 tomatoes Rs 30 Cost of one tomato 30 / 5 Rs 6/li>Calculating the Cost of One Kilogram of Potatoes
Similarly, to find the cost of one kilogram of potatoes:
Cost of 3 kilograms of potatoes Rs 120 Cost of one kilogram of potatoes 120 / 3 Rs 40Calculating the Total Cost of Six Tomatoes and Four Kilograms of Potatoes
Now, let's use these individual costs to find the total cost of six tomatoes and four kilograms of potatoes.
Step-by-Step Calculation
Calculating the Cost of Six Tomatoes
Since the cost of one tomato is Rs 6:
Cost of 6 tomatoes 6 x 6 Rs 36Calculating the Cost of Four Kilograms of Potatoes
And since the cost of one kilogram of potatoes is Rs 40:
Cost of 4 kilograms of potatoes 4 x 40 Rs 160Total Cost Calculation
Now, let's sum up the costs:
Total cost Rs 36 (six tomatoes) Rs 160 (four kilograms of potatoes) Rs 196Conclusion
In conclusion, the total cost of half a dozen tomatoes and four kilograms of potatoes is Rs 196. This example demonstrates how to break down and calculate the cost of goods, which is a fundamental skill in daily transactions and budgeting.
