Introduction

In the world of business, profit margins are crucial for the success of any venture. A vendor who buys lemons at a low price and sells them at a higher price can gain a significant profit. In this article, we will explore a scenario where a vendor buys 5 lemons for a rupee and wants to know how many lemons must be sold for $₹ 7$ to gain a profit of $16 \frac{2}{3} \%$ .

Calculating the Cost Price

To calculate the cost price of the lemons, we need to know the cost of buying 5 lemons for a rupee. Since the cost of 5 lemons is $₹ 1$ , the cost of 1 lemon is $\frac{₹ 1}{5} = ₹ 0.2$ .

Calculating the Selling Price

The vendor wants to gain a profit of $16 \frac{2}{3} \%$ . To calculate the selling price, we need to find the amount of profit that needs to be added to the cost price. Let's assume the selling price is $₹ x$ . The profit percentage can be calculated as:

Profit Percentage = (Profit / Cost Price) × 100

We know that the profit percentage is $16 \frac{2}{3} \%$ , which is equal to $\frac{50}{3} \%$ . We can set up the equation as:

$\frac{50}{3} \% = \frac{(x - 0.2)}{0.2} × 100$

Solving for x

To solve for x, we can start by simplifying the equation:

$\frac{50}{3} \% = \frac{(x - 0.2)}{0.2} × 100$

$\frac{50}{3} = \frac{(x - 0.2)}{0.2} × \frac{100}{100}$

$\frac{50}{3} = \frac{(x - 0.2)}{0.2} × 1$

$\frac{50}{3} = \frac{(x - 0.2)}{0.2}$

Now, we can cross-multiply:

$50 × 0.2 = 3(x - 0.2)$

$10 = 3x - 0.6$

$10 + 0.6 = 3x$

$10.6 = 3x$

Finding the Selling Price

Now that we have the value of x, we can find the selling price:

$x = \frac{10.6}{3}$

$x = 3.5333...$

So, the selling price is approximately $₹ 3.53$ .

Calculating the Number of Lemons to be Sold

Since the vendor wants to sell the lemons for $₹ 7$ , we need to find the number of lemons that can be sold at this price. Let's assume the number of lemons to be sold is y. We can set up the equation as:

$₹ 3.53 = ₹ 7 × \frac{1}{y}$

Solving for y

To solve for y, we can start by simplifying the equation:

$₹ 3.53 = ₹ 7 × \frac{1}{y}$

$\frac{₹ 3.53}{₹ 7} = \frac{1}{y}$

$\frac{3.53}{7} = \frac{1}{y}$

Now, we can cross-multiply:

$3.53 × y = 7 × 1$

$3.53y = 7$

Finding the Number of Lemons

Now that we have the value of y, we can find the number of lemons to be sold:

$y = \frac{7}{3.53}$

$y = 1.977...$

So, the vendor needs to sell approximately 2 lemons for $₹ 7$ to gain a profit of $16 \frac{2}{3} \%$ .

Conclusion

In this article, we explored a scenario where a vendor buys 5 lemons for a rupee and wants to know how many lemons must be sold for $₹ 7$ to gain a profit of $16 \frac{2}{3} \%$ . We calculated the cost price, selling price, and the number of lemons to be sold. The results show that the vendor needs to sell approximately 2 lemons for $₹ 7$ to gain the desired profit.

Future Work

In the future, we can explore more scenarios where vendors buy and sell lemons at different prices to gain different profit margins. We can also calculate the break-even point and the revenue generated by selling the lemons.

Limitations

One limitation of this article is that it assumes a fixed cost price and selling price. In reality, the cost price and selling price may vary depending on various factors such as market conditions, competition, and seasonality. Therefore, the results of this article may not be applicable in all scenarios.

Conclusion

In conclusion, this article provides a step-by-step guide on how to calculate the number of lemons to be sold for a given profit margin. The results show that the vendor needs to sell approximately 2 lemons for $₹ 7$ to gain a profit of $16 \frac{2}{3} \%$ . This article can be useful for vendors who want to calculate their profit margins and make informed decisions about their business.
