Profit Calculation from Currency Exchange Rates: A Comprehensive Guide

For traders and financial enthusiasts, understanding how to calculate profit from currency exchange rates is a fundamental concept. This article will dive into a specific problem where we need to determine the number of US dollars that should be bought and sold to achieve a profit of Rs 10. We will explore the process step-by-step and provide a detailed solution.

Understanding the Buying and Selling Rates

In currency exchange, two rates are crucial: Buys Rates: The rate at which a currency is bought, often denoted as Rs 115.25 in this case. selling rate: The rate at which a currency is sold, denoted as Rs 116.5 in this context.

Step-by-Step Calculation

To determine how many US dollars should be bought and sold to achieve a profit of Rs 10, we follow these steps:

Identify the buying and selling rates: Buying rate Rs 115.25 Selling rate Rs 116.50 Calculate the profit per dollar: Profit per dollar Selling rate - Buying rate 116.50 - 115.25 1.25 Rs Determine the number of dollars required to achieve a profit of Rs 10: Number of dollars Desired profit in Rs / Profit per dollar 10 / 1.25 8 dollars

Alternative Method

Another way to solve this problem involves using a different approach:

Let the required dollars be X. Profit Rs 116.5 - 115.25X Rs 115.2510 Therefore, X 1152.5 / 1.25 922. Cost Price (C.P.) of 1 dollar Rs. 115.25 Selling Price (S.P.) of 1 dollar Rs. 116.5 Profit on 1 dollar S.P. of 1 dollar - C.P. of 1 dollar Rs. 116.5 - Rs. 115.25 Rs. 1.25 We need a total profit of 10. Therefore, 10 Rs. 116.5 * 10 Rs. 1165 Rs. 1.25 1 dollar Rs. 1 1 / 1.25 0.8 dollars Rs. 1165 0.8 * 1165 932 Therefore, 932 dollars should be bought and sold to have a profit of 10 Rs.

Conclusion
