Representation of Money with Notes Coins Symbols and Solved Examples
The concept of Representation Of Money is a foundational topic in both mathematics and daily life. Understanding how money is visually, numerically, and symbolically represented is essential for school exams, competitive tests, and practical situations like shopping or budgeting. Mastering this topic helps students make sense of real-world numerical problems with ease.
Understanding the Representation Of Money
The representation of money refers to the different ways in which money is shown, counted, and used in mathematics and everyday transactions. This includes physical forms like coins and notes, numerical forms using numbers and decimals, and symbols such as ₹ (Rupee), $ (Dollar), or £ (Pound). Recognizing these forms is important for calculation, identification, and comparison of currency values.
Money is represented in two main ways:
- Physical representation: Coins and notes of different values, colors, sizes, and shapes.
- Numerical/Mathematical representation: Writing amounts using digits, decimal points, and currency symbols (for example, ₹45.75 or Rs. 45.75).
At Vedantu, we simplify concepts like the physical and visual representation of money, helping students identify denominations and understand calculations confidently.
Forms and Symbols of Money
Money takes various forms, each with its own way of being represented:

Numerical Representation and Conversion
In mathematics and daily life, money is usually represented numerically using numbers and decimal notation. In India, 1 rupee is equal to 100 paise.
| Representation | Example | Explanation |
|---|---|---|
| Numbers Only | ₹38.75 | 38 rupees and 75 paise (38 x 1 rupee + 75 paise) |
| Words | “Thirty-eight rupees seventy-five paise” | Same amount written in words |
| Paise Only | 3875 paise | ₹38.75 = 38 rupees x 100 + 75 = 3875 paise |
Steps for Rupees–Paise Conversion
- To convert rupees to paise: Multiply by 100.
(E.g., ₹5 = 5 × 100 = 500 paise) - To convert paise to rupees: Divide by 100.
(E.g., 250 paise = 250 ÷ 100 = ₹2.50)

Step 2: ₹17 rupees 35 paise = ₹17.35 -
Convert ₹8.50 to paise.
Step 1: Multiply rupees by 100: 8 × 100 = 800
Step 2: Add 50 paise: 800 + 50 = 850 paise -
Express 425 paise in rupees.
Step 1: Divide by 100: 425 ÷ 100 = ₹4.25
Practice Problems
- Write Rs. 31 and 60 paise in numerical form.
- Convert 7 rupees 85 paise into paise.
- Write 320 paise as rupees and paise.
- How do you represent Rs. 56.25 in words?
- If you have two ₹10 notes and three ₹5 coins, what is your total in rupees?
Common Mistakes to Avoid
- Confusing rupees with paise and writing amounts incorrectly (e.g., writing 8.50 as 850 rupees instead of ₹8.50).
