Introduction

As a shopkeeper, managing inventory is crucial to running a successful business. In this scenario, we are tasked with determining the remaining mass of apples after a shopkeeper sells various quantities throughout the day. We will use mathematical calculations to find the solution.

Understanding the Problem

The shopkeeper starts with 227 kg of apples and sells three different quantities:

$3 \frac{1}{2}$ kg
540 g
45 kg

To find the remaining mass of apples, we need to subtract the total mass sold from the initial mass.

Converting Quantities to a Common Unit

Before we can perform the subtraction, we need to convert all quantities to a common unit. Since the initial mass is given in kilograms, we will convert the other quantities to kilograms as well.

$3 \frac{1}{2}$ kg is already in kilograms.
540 g is equivalent to 0.54 kg (since 1 kg = 1000 g).
45 kg is already in kilograms.

Calculating the Total Mass Sold

Now that all quantities are in kilograms, we can calculate the total mass sold by adding the three quantities together:

Total mass sold = $3 \frac{1}{2}$ kg + 0.54 kg + 45 kg

To add these quantities, we need to convert the mixed number $3 \frac{1}{2}$ to an improper fraction or a decimal. Let's convert it to a decimal:

$3 \frac{1}{2}$ = 3.5 kg

Now we can add the quantities:

Total mass sold = 3.5 kg + 0.54 kg + 45 kg Total mass sold = 49.04 kg

Calculating the Remaining Mass

Now that we have the total mass sold, we can subtract it from the initial mass to find the remaining mass:

Remaining mass = Initial mass - Total mass sold Remaining mass = 227 kg - 49.04 kg Remaining mass = 177.96 kg

Conclusion

In this scenario, the shopkeeper starts with 227 kg of apples and sells a total of 49.04 kg. To find the remaining mass, we subtract the total mass sold from the initial mass, resulting in 177.96 kg of apples remaining.

Key Takeaways

To solve this problem, we need to convert all quantities to a common unit (kilograms).
We calculate the total mass sold by adding the three quantities together.
We subtract the total mass sold from the initial mass to find the remaining mass.

Real-World Applications

This problem has real-world applications in various fields, such as:

Inventory management: Understanding how to calculate remaining stock is crucial for businesses that deal with perishable goods.
Sales and marketing: Calculating the total mass sold can help businesses determine their sales performance and adjust their strategies accordingly.
Mathematics: This problem demonstrates the importance of converting units and performing calculations to solve real-world problems.

A Shopkeeper's Apple Sales: Q&A =====================================

Introduction

In our previous article, we explored how to calculate the remaining mass of apples after a shopkeeper sells various quantities throughout the day. In this article, we will address some frequently asked questions related to this topic.

Q: What is the initial mass of apples?

A: The initial mass of apples is 227 kg.

Q: What are the three quantities sold by the shopkeeper?

A: The three quantities sold by the shopkeeper are:

$3 \frac{1}{2}$ kg
540 g
45 kg

Q: How do I convert 540 g to kilograms?

A: To convert 540 g to kilograms, you can divide by 1000 (since 1 kg = 1000 g):

540 g ÷ 1000 = 0.54 kg

Q: How do I add mixed numbers and decimals?

A: To add mixed numbers and decimals, you can convert the mixed number to a decimal or an improper fraction. In this case, we converted $3 \frac{1}{2}$ to a decimal:

$3 \frac{1}{2}$ = 3.5 kg

Then we added the quantities:

Total mass sold = 3.5 kg + 0.54 kg + 45 kg Total mass sold = 49.04 kg

Q: How do I calculate the remaining mass of apples?

A: To calculate the remaining mass of apples, you can subtract the total mass sold from the initial mass:

Remaining mass = Initial mass - Total mass sold Remaining mass = 227 kg - 49.04 kg Remaining mass = 177.96 kg

Q: What are some real-world applications of this problem?

A: This problem has real-world applications in various fields, such as:

Inventory management: Understanding how to calculate remaining stock is crucial for businesses that deal with perishable goods.
Sales and marketing: Calculating the total mass sold can help businesses determine their sales performance and adjust their strategies accordingly.
Mathematics: This problem demonstrates the importance of converting units and performing calculations to solve real-world problems.
