Introduction

In this article, we will delve into a simple yet intriguing mathematical problem that involves buying stamps of equal value. The problem states that five stamps of equal value cost rupees 36. We are then asked to determine how many stamps of the same value can be bought for rupees 72. This problem requires us to apply basic mathematical concepts, such as division and multiplication, to arrive at the solution.

Understanding the Problem

Let's break down the problem and understand what is being asked. We are given that five stamps of equal value cost rupees 36. This means that the cost of one stamp is rupees 36 divided by 5, which equals rupees 7.2. Now, we are asked to find out how many stamps of the same value can be bought for rupees 72.

Calculating the Number of Stamps

To solve this problem, we need to divide the total amount of money available (rupees 72) by the cost of one stamp (rupees 7.2). This will give us the number of stamps that can be bought.

Number of stamps = Total amount of money / Cost of one stamp
= 72 / 7.2
= 10

Conclusion

Therefore, we can conclude that 10 stamps of the same value can be bought for rupees 72.

Why This Problem Matters

This problem may seem simple, but it requires us to apply basic mathematical concepts in a practical way. In real-life scenarios, we often encounter problems that involve division and multiplication, and being able to solve them efficiently is crucial. This problem also highlights the importance of understanding the cost of individual items and being able to calculate the total cost of a purchase.
