In the world of mathematics, subtraction is an essential concept to understand. And when it comes to money, the rules remain the same. In this article, we will delve into the art of subtracting money involving both rupees and paise (the subunit of the Indian currency) and find the difference.

I. Subtraction with conversion:

When subtracting money using the conversion method, we first convert both rupees and paise into paise and then subtract the smaller amount from the greater amount. The resulting numbers are subtracted as ordinary numbers, and if necessary, we place a dot after two digits from the right. Finally, we express the difference in rupees and paise.

Consider the following examples:

1. Find the difference between Rs 58.49 and Rs 34.05.
Solution: Rs 58.49 = 5849 paise
Rs 34.05 = 3405 paise
Difference = 2444 paise (or Rs 24.44)

2. Find the difference between Rs 25.68 and Rs 73.94
Solution: Rs 73.94 = 7394 paise
Rs 25.68 = 2568 paise
Difference = 4826 paise (or Rs 48.26)

II. Subtraction without conversion:

In subtraction without conversion, we arrange the given amounts in columns. Each column represents the corresponding unit (paise under paise, rupees under rupees, and the dot under the dot). We then subtract the numbers as ordinary numbers, keeping the decimal point in its place.

Consider the following examples:

1. Subtract Rs 32.84 from Rs 72.98
Solution: Rs 72.98
– Rs 32.84
Rs 40.14

2. Subtract Rs 36.39 from Rs 58.25
Solution: Rs 58.25
– Rs 36.39
Rs 21.86

3. Subtract Rs.185.80 from Rs. 301.35
Solution: Rs. 301.35
– Rs. 185.80
Rs. 115.55

Worked-out examples on subtraction of money:

1. Subtract Rs. 21.24 from Rs. 74.75
Solution: Method 1 (with conversion into paise):
Rs. 74.75 = 7475 paise
Rs. 21.24 = 2124 paise
Difference = 5351 paise (or Rs. 53.51)

2. Subtract Rs. 28.35 from Rs. 57.30
Solution: Method 2 (without conversion into paise):
Rs. 57.30
– Rs. 28.35
Rs. 28.95

3. Subtract Rs. 33.80 from Rs. 65.50
Solution: Rs. 65.50
– Rs. 33.80
Rs. 31.70

Word Problems on Subtraction of Money:

1. Michael buys a notebook for Rs. 19.50 and pays the shopkeeper with a Rs. 100.00 note. How much money will he get back?
Solution: Cost of a notebook = Rs. 19.50
Cash paid = Rs. 100.00
Money received back = Rs. 80.50

2. Gloria bought a book for Rs. 125.50. If she paid with a 500 rupee note, how much money did she get back?
Solution: Gloria paid Rs. 125.50 using a 500 rupee note
She received back Rs. 374.50

Frequently Asked Questions

Q: What is subtraction of money?

A: Subtraction of money is a mathematical operation that involves deducting one amount from another to find the difference.

Q: How do I perform subtraction with conversion?

A: To perform subtraction with conversion, first, ensure that both amounts are in the same currency. If they are not, convert one amount to the currency of the other using the appropriate exchange rate. Once both amounts are in the same currency, subtract the smaller amount from the larger amount to get the result.

Q: Can subtraction of money result in negative values?

A: Yes, subtraction of money can result in negative values. If the amount being subtracted is greater than the original amount, the result will be negative, indicating a deficit or debt.

Q: Is it possible to subtract different currencies directly?

A: No, it is not possible to directly subtract different currencies. You need to convert them to the same currency first using appropriate exchange rates before performing the subtraction.

Q: How can I convert currencies for subtraction?

A: You can convert currencies using various methods, such as online currency converters or consulting a financial institution for current exchange rates. Once you have the exchange rates, multiply the amount in the original currency by the exchange rate to obtain the equivalent amount in the desired currency.

Q: Are there any specific rules for subtracting money?

A: The rules for subtracting money are similar to regular subtraction. Line up the decimal points of the amounts being subtracted, and subtract digit by digit, carrying over if necessary. Ensure that the decimal point is in the correct position in the final result.
