Definition
What is it?
In a transaction, 'change' is the money you get back when you pay more than the actual cost of an item. It is the difference between the amount you paid and the price of the item.
Simple Example
Quick Example
Imagine you buy a packet of Lays chips for ₹20. If you give the shopkeeper a ₹50 note, the money he returns to you is the change. In this case, you get ₹30 back.
Worked Example
Step-by-Step
Let's say you want to buy a delicious samosa for ₹15. You only have a ₹20 note to pay. How much change will you get back?
1. Identify the cost of the item: Samosa costs ₹15.
---
2. Identify the amount you paid: You paid ₹20.
---
3. To find the change, subtract the cost from the amount paid.
---
4. Change = Amount Paid - Cost of Item
---
5. Change = ₹20 - ₹15
---
6. Change = ₹5
---
So, you will get ₹5 back as change.
Why It Matters
Understanding change is crucial for managing your money daily and in bigger financial decisions. It's a basic concept used in finance for budgeting, in economics for calculating value, and even in computing for programming payment systems. Cashiers, business owners, and even app developers use this concept constantly.
