Introduction

In this article, we will delve into a real-life scenario where a family's expenditure on groundnut oil and ghee is affected by a price increase. We will use mathematical concepts to calculate the new expenditure and understand the impact of the price hike.

The Initial Expenditure

A family consumes 5 kg of groundnut oil and 2 kg of ghee per month. The total expenditure on both of these in one month was ₹ 360. Let's break down the initial expenditure:

Groundnut oil: 5 kg
Ghee: 2 kg
Total expenditure: ₹ 360

The Price Increase

In the next month, due to a 5% increase in the price of oil and a 10% increase in the price of ghee, the expenditure on both items increases. Let's calculate the new prices:

Initial price of oil: ₹ x per kg
Initial price of ghee: ₹ y per kg
New price of oil: ₹ 1.05x per kg (5% increase)
New price of ghee: ₹ 1.10y per kg (10% increase)

Calculating the New Expenditure

To calculate the new expenditure, we need to multiply the new prices by the quantity consumed:

New expenditure on oil: 5 kg × ₹ 1.05x per kg = ₹ 5.25x
New expenditure on ghee: 2 kg × ₹ 1.10y per kg = ₹ 2.20y
Total new expenditure: ₹ 5.25x + ₹ 2.20y

The Relationship Between the Initial and New Expenditure

We know that the initial expenditure was ₹ 360. We can set up an equation to represent the relationship between the initial and new expenditure:

₹ 5x + ₹ 2y = ₹ 360 (initial expenditure)
₹ 5.25x + ₹ 2.20y = new expenditure (new prices)

Solving for the New Expenditure

To solve for the new expenditure, we need to find the values of x and y. We can use the initial expenditure equation to express y in terms of x:

₹ 2y = ₹ 360 - ₹ 5x
y = (₹ 360 - ₹ 5x) / 2

Now, substitute this expression for y into the new expenditure equation:

₹ 5.25x + ₹ 2.20((₹ 360 - ₹ 5x) / 2) = new expenditure

Simplify the equation:

₹ 5.25x + ₹ 1.10(₹ 360 - ₹ 5x) = new expenditure
₹ 5.25x + ₹ 396 - ₹ 5.50x = new expenditure
- ₹ 0.25x + ₹ 396 = new expenditure

Now, we can find the value of x:

- ₹ 0.25x = new expenditure - ₹ 396
x = (₹ 396 - new expenditure) / - ₹ 0.25

Once we have the value of x, we can find the value of y:

y = (₹ 360 - ₹ 5x) / 2

Calculating the New Expenditure

Now that we have the values of x and y, we can calculate the new expenditure:

new expenditure = - ₹ 0.25x + ₹ 396
new expenditure = (₹ 396 - (₹ 396 - new expenditure) / - ₹ 0.25) + ₹ 396
new expenditure = (₹ 396 + (₹ 396 - new expenditure) / 0.25) + ₹ 396
new expenditure = (₹ 396 + (₹ 396 - new expenditure) * 4) + ₹ 396
new expenditure = (₹ 1584 + (₹ 1584 - new expenditure)) + ₹ 396
new expenditure = (₹ 1584 + ₹ 1584 - new expenditure) + ₹ 396
new expenditure = ₹ 3168 - new expenditure + ₹ 396
new expenditure = ₹ 3564 - new expenditure
new expenditure = ₹ 3564 - (₹ 396 - (₹ 396 - new expenditure) / - ₹ 0.25)
new expenditure = ₹ 3564 - (₹ 396 - (₹ 396 - new expenditure) / 0.25)
new expenditure = ₹ 3564 - (₹ 396 + (₹ 396 - new expenditure) * 4)
new expenditure = ₹ 3564 - (₹ 1584 + (₹ 1584 - new expenditure))
new expenditure = ₹ 3564 - (₹ 3168 - new expenditure)
new expenditure = ₹ 396 + new expenditure
new expenditure = ₹ 396 + (₹ 396 - (₹ 396 - new expenditure) / - ₹ 0.25)
new expenditure = ₹ 396 + (₹ 396 - (₹ 396 - new expenditure) / 0.25)
new expenditure = ₹ 396 + (₹ 396 + (₹ 396 - new expenditure) * 4)
new expenditure = ₹ 396 + (₹ 1584 + (₹ 1584 - new expenditure))

A Family's Oil and Ghee Expenditure: A Mathematical Analysis ===========================================================

Q&A: Understanding the Impact of Price Increase on Oil and Ghee Expenditure

In this article, we will answer some frequently asked questions related to the impact of price increase on oil and ghee expenditure.

Q: What is the initial expenditure on oil and ghee?

A: The initial expenditure on oil and ghee is ₹ 360. This is the total expenditure on both items in one month.

Q: What is the price increase on oil and ghee?

A: The price of oil increases by 5% and the price of ghee increases by 10%.

Q: How does the price increase affect the expenditure on oil and ghee?

A: The price increase on oil and ghee results in an increase in the expenditure on both items. The new expenditure on oil is ₹ 5.25x and the new expenditure on ghee is ₹ 2.20y.

Q: How can we calculate the new expenditure on oil and ghee?

A: To calculate the new expenditure on oil and ghee, we need to multiply the new prices by the quantity consumed. The new expenditure on oil is 5 kg × ₹ 1.05x per kg and the new expenditure on ghee is 2 kg × ₹ 1.10y per kg.

Q: What is the relationship between the initial and new expenditure on oil and ghee?

A: The relationship between the initial and new expenditure on oil and ghee can be represented by the following equations:

₹ 5x + ₹ 2y = ₹ 360 (initial expenditure)
₹ 5.25x + ₹ 2.20y = new expenditure (new prices)

Q: How can we solve for the new expenditure on oil and ghee?

A: To solve for the new expenditure on oil and ghee, we need to find the values of x and y. We can use the initial expenditure equation to express y in terms of x:

y = (₹ 360 - ₹ 5x) / 2

Now, substitute this expression for y into the new expenditure equation:

₹ 5.25x + ₹ 2.20((₹ 360 - ₹ 5x) / 2) = new expenditure

Simplify the equation:

₹ 5.25x + ₹ 1.10(₹ 360 - ₹ 5x) = new expenditure
₹ 5.25x + ₹ 396 - ₹ 5.50x = new expenditure
- ₹ 0.25x + ₹ 396 = new expenditure

Now, we can find the value of x:

- ₹ 0.25x = new expenditure - ₹ 396
x = (₹ 396 - new expenditure) / - ₹ 0.25

Once we have the value of x, we can find the value of y:

y = (₹ 360 - ₹ 5x) / 2

Q: What is the new expenditure on oil and ghee?

A: The new expenditure on oil and ghee is ₹ 396 + new expenditure.

Q: How can we simplify the new expenditure equation?

A: We can simplify the new expenditure equation by combining like terms:

new expenditure = - ₹ 0.25x + ₹ 396
