Reading and Writing Money

How to Write Rupees

₹5 (5 rupees)
₹25 (25 rupees)
₹350 (350 rupees)

How to Write Rupees and Paise Together

₹5.50 (5 rupees and 50 paise)
₹12.25 (12 rupees and 25 paise)
₹100.05 (100 rupees and 5 paise)

The DOT (.) separates rupees and paise.

Converting Rupees to Paise

Rule

Multiply the rupees by 100 to get paise.

Rupees	Conversion	Paise
₹1	1 × 100	100 p
₹5	5 × 100	500 p
₹10	10 × 100	1000 p
₹25	25 × 100	2500 p
₹100	100 × 100	10,000 p

Examples with Rupees and Paise

Amount	In Paise
₹5.50	500 + 50 = 550 p
₹12.25	1200 + 25 = 1225 p
₹100.05	10,000 + 5 = 10,005 p
₹0.75	75 p

Converting Paise to Rupees

Rule

Divide the paise by 100 to get rupees.

Paise	Conversion	Rupees
100 p	100 ÷ 100	₹1
500 p	500 ÷ 100	₹5
750 p	750 ÷ 100	₹7.50
1250 p	1250 ÷ 100	₹12.50
10,000 p	10,000 ÷ 100	₹100

Practice

250 p = ₹2.50
1050 p = ₹10.50
99 p = ₹0.99
2000 p = ₹20.00

Making Bills

A BILL is a list of things you buy with their PRICES and the TOTAL amount.

Example 1: Stationery Shop Bill

Item	Quantity	Price Each	Total
Pencil	2	₹5	₹10
Eraser	1	₹3	₹3
Sharpener	1	₹5	₹5
Notebook	3	₹20	₹60
Grand Total			₹78

Example 2: Fruit Shop Bill

Item	Quantity	Price per kg	Total
Apples	2 kg	₹80/kg	₹160
Bananas	1 dozen	₹40/dozen	₹40
Oranges	1 kg	₹60/kg	₹60
Grapes	500 g	₹100/kg	₹50
Grand Total			₹310

Making Your Own Bill

Item	Quantity	Price	Total
Samosa	4	₹10	₹40
Juice	2	₹25	₹50
Biscuits	1	₹15	₹15
Total			₹105

Simple Money Transactions

Problem 1: How Much Did I Spend?

Riya buys a book for ₹45 and a pen for ₹15. How much does she spend?

Solution: ₹45 + ₹15 = ₹60

Problem 2: How Much Change?

Ritu buys a toy for ₹65. She gives a ₹100 note. How much change does she get?

Solution: ₹100 - ₹65 = ₹35 change

Problem 3: How Much More?

A bicycle costs ₹1,200. Amit has ₹850. How much more does he need?

Solution: ₹1,200 - ₹850 = ₹350 more needed

Problem 4: Total Cost

Ravi buys:

2 kg of rice at ₹30/kg = ₹60
1 kg of dal at ₹80/kg = ₹80
500 g of sugar at ₹40/kg = ₹20

Total = ₹60 + ₹80 + ₹20 = ₹160

Problem 5: Shopping with a Budget

Sita has ₹200. She buys a dress for ₹125. How much is left?

Solution: ₹200 - ₹125 = ₹75 left

Saving Money

Why Save?

To buy something you REALLY want
For EMERGENCIES
To learn GOOD HABITS

How to Save

Put money in a PIGGY BANK
Save some of your POCKET MONEY every week
Don't SPEND all your money at once

Saving Challenge

Week	Saved	Total Saved
Week 1	₹10	₹10
Week 2	₹10	₹20
Week 3	₹10	₹30
Week 4	₹10	₹40
Week 5	₹10	₹50

If you save ₹10 every week, you will have ₹520 in one year!

Common Mistakes

'₹1 = 10 paise.' — No! ₹1 = 100 paise. One rupee equals ONE HUNDRED paise.
'₹5.50 and ₹5.05 are the same.' — No! ₹5.50 is 5 rupees and 50 paise. ₹5.05 is 5 rupees and 5 paise. They are DIFFERENT amounts.
'When I give a ₹100 note for a ₹45 item, I get ₹65 change.' — No! Changes = 100 - 45 = ₹55, not ₹65.
'Rupees and paise can be added directly.' — No! Always convert to the SAME unit first. Add rupees to rupees and paise to paise.
'A 10-rupee note is worth more than ten 1-rupee coins.' — No! Both are worth EXACTLY ₹10. Different forms, same value.

Quick Self-Test

Q1: How many paise are in ₹1? A1: 100 paise.

Q2: Convert ₹5.75 into paise. A2: 575 paise.

Q3: Convert 750 paise into rupees. A3: ₹7.50.

Q4: A chocolate costs ₹15. You give ₹20. How much change? A4: ₹20 - ₹15 = ₹5 change.

Q5: Riya has ₹250. She buys a book for ₹85. How much does she have now? A5: ₹250 - ₹85 = ₹165.

Q6: What is the colour of the ₹100 note? A6: Lavender.

Q7: Make a bill: 2 pens at ₹10 each, 1 scale at ₹5, 3 erasers at ₹3 each. A7: Pens: 2 × ₹10 = ₹20, Scale: 1 × ₹5 = ₹5, Erasers: 3 × ₹3 = ₹9. Total = ₹20 + ₹5 + ₹9 = ₹34.

Q8: If you save ₹5 every day, how much do you save in a week? A8: 7 × ₹5 = ₹35.

Key formulas & results

Indian currency basics

Coins: ₹1, ₹2, ₹5, ₹10, ₹20 · Notes: ₹5, ₹10, ₹20, ₹50, ₹100, ₹200, ₹500 · ₹1 = 100 paise · Prices are written as ₹ followed by rupees, a dot, and paise: ₹25.50 means 25 rupees and 50 paise

The symbol ₹ was adopted in 2010. It is a combination of Devanagari 'र' (Ra) and Roman 'R'.

Rupee-Paise conversion

₹1 = 100 paise · To convert rupees to paise: multiply by 100 (₹5 = 5 × 100 = 500 paise) · ₹5.50 = 5 rupees 50 paise = 550 paise · ₹2.25 = 225 paise · To convert paise to rupees: divide by 100 (250p = ₹2.50, 575p = ₹5.75)

The decimal point separates rupees (left) from paise (right). ₹12.75: 12 rupees, 75 paise.

Making a bill (total cost)

List all items with their prices · Add all prices: Total = Price₁ + Price₂ + Price₃ + ... · Write the total in ₹ format · Example: Pen ₹15 + Notebook ₹35 + Eraser ₹5 = Total ₹55

Always write ₹ before the amount. Line up the decimal points when adding multiple amounts.

Calculating change

Change = Money given − Total cost. Example: Total cost = ₹73. Money given = ₹100. Change = 100 − 73 = ₹27. OR: count up from 73 to 100: 73+7=80, 80+20=100 → Change = ₹7+₹20 = ₹27.

Always verify: Total cost + Change should equal the money given. This is how shopkeepers check.

⚠️

Common mistakes & fixes

These are the exact errors that cost students marks in board exams. Read them once, save yourself the trouble.

WATCH OUT

✗ Writing ₹15.5 instead of ₹15.50 — omitting the zero in paise

✓ Paise is always written with TWO digits after the decimal. ₹15.5 means 15 rupees 5 paise? No — write ₹15.50 (15 rupees 50 paise). If 5 paise, write ₹15.05.

WATCH OUT

✗ Adding money without lining up the decimal points

✓ Always align decimal points vertically when adding: ₹25.50 + ₹7.25. Line up the dots — ones under ones, tens under tens — just like regular addition.

WATCH OUT

✗ In conversion, confusing 150 paise as ₹150 or ₹1.50 as 1500 paise

✓ 100 paise = ₹1. So 150 paise = ₹1.50 (NOT ₹150). ₹1.50 = 1 rupee 50 paise = 150 paise. The decimal point shifts 2 places: rupees × 100 = paise.

Prep strategy

Show real currency — let the child hold and identify each coin and note. Talk about the symbols and people on them
Set up a 'shop' at home: price toys or books, use play money. Let the child be customer and shopkeeper
When shopping, let your child calculate the total and count the change — real practice is best
Practice conversion daily: 'What is ₹3.50 in paise? What is 450 paise in rupees?'
Play 'I have this, can I buy that?': 'You have ₹50. This toy costs ₹35. Can you also buy a ₹20 book?'
