If Weight Of A 5-rupee Coin Is 8 G, Then Weight Of 50 Coins Of 5 Rupees Is: (i) 480 G (ii) 400 G (iii) 440 (iv) 520 G
Introduction
In this article, we will delve into the world of mathematics and explore a simple yet intriguing problem related to the weight of coins. Specifically, we will examine the weight of a 5-rupee coin and calculate the total weight of 50 such coins. This problem may seem straightforward, but it requires a clear understanding of mathematical concepts and operations.
The Problem
The problem states that the weight of a 5-rupee coin is 8 grams. We are asked to find the total weight of 50 such coins. To solve this problem, we need to apply basic mathematical operations, specifically multiplication.
Calculating the Total Weight
To find the total weight of 50 coins, we need to multiply the weight of a single coin by 50. This can be represented mathematically as:
Weight of 50 coins = Weight of 1 coin × 50
Substituting the given value, we get:
Weight of 50 coins = 8 g × 50
Using the multiplication operation, we can calculate the total weight as follows:
Weight of 50 coins = 8 g × 50 = 400 g
Therefore, the total weight of 50 coins of 5 rupees is 400 g.
Analyzing the Options
Now that we have calculated the total weight of 50 coins, let's analyze the given options:
- (i) 480 g
- (ii) 400 g
- (iii) 440
- (iv) 520 g
Based on our calculation, the correct answer is option (ii) 400 g.
Conclusion
In this article, we have applied basic mathematical operations to solve a simple problem related to the weight of coins. By understanding the concept of multiplication and applying it to the given problem, we have arrived at the correct answer. This problem serves as a reminder of the importance of mathematical operations in real-life scenarios.
Additional Tips and Variations
While this problem may seem straightforward, there are several variations and tips that can be applied to make it more challenging or interesting:
- Weight of different denominations: What if we were asked to find the total weight of coins of different denominations, such as 1-rupee, 2-rupee, or 10-rupee coins?
- Weight of coins with different materials: What if the coins were made of different materials, such as copper, silver, or gold?
- Weight of coins with different shapes: What if the coins had different shapes, such as circular, square, or triangular?
These variations can add an extra layer of complexity and interest to the problem, making it more engaging and challenging for math enthusiasts.
