Rupees, Bills and Change: Class 3 Study Guide
A bill shows what we bought and what we must pay. The change is what the shopkeeper gives back.
When we buy things, a shopkeeper writes or prints a bill. It lists each item with its price and the total. If we pay with more than the total, we get change.
In Class 3, children add prices in rupees and paise, for example ₹12.50 + ₹7.25, and subtract to find the change. 100 paise make ₹1.
A shopping bill
| Item | Quantity | Price |
|---|---|---|
| Notebook | 2 | ₹60.00 |
| Pencil | 5 | ₹25.00 |
| Eraser | 1 | ₹7.50 |
| Total | ₹92.50 |
Finding the change
To find the change, subtract the total from the money paid. If the bill is ₹92.50 and you pay with ₹100, the change is ₹100 − ₹92.50 = ₹7.50. Shopkeepers often count on instead: from 92.50 add 50 paise to reach ₹93, then ₹7 more to reach ₹100. The change is ₹7.50.
To get the total.
Which note or coin.
From the total to the amount paid.
Total + change = money paid.
Adding rupees and paise
Line up the dots (decimal points) so that paise are under paise and rupees under rupees. Add the paise first. If they make 100 or more, carry 1 rupee. Example: ₹12.50 + ₹7.25 = ₹19.75.
Worked examples and common mistakes
Example: Two pens cost ₹15 each and a ruler costs ₹10. Total = 15 + 15 + 10 = ₹40. Paying with ₹50 gives ₹10 change. Common mistakes: not lining up the decimal points, and forgetting to add the price twice when buying two of an item. Write the quantity next to each price.
