Explanations:In this problem, we are dealing with a basic arithmetic operation involving subtraction. The context is a financial transaction where Usha bought a handmade silk mirror work wall hanging for 7,400 and later sold it for 350 less than the original price. The task is to determine the selling price.
The concept of subtraction is fundamental in mathematics and is used in various real-life scenarios, such as calculating the final price after a discount, determining the change to be given, or finding the difference between two quantities. In this case, we need to subtract 350 from the original price of 7,400 to find the selling price.
Let's break down the calculation step-by-step:
1. Identify the original price: 7,400.
2. Identify the amount less: 350.
3. Perform the subtraction: 7,400 - 350.
Subtracting 350 from 7,400 involves aligning the numbers by their place values and performing the subtraction:
7,400
- 350
----
7,050
Thus, the selling price is 7,050. This matches Option A, which is the correct answer.
It is important to ensure that the operation performed is subtraction and not addition, as adding 350 to the original price would give an incorrect result. Additionally, the amount subtracted should be exactly 350, not a larger or smaller amount, to accurately reflect the selling price.
Understanding this concept is crucial for solving similar problems involving financial transactions and basic arithmetic operations. It is a foundational skill that is often tested in primary school mathematics and can be applied in various practical situations.
