All questions of Money for Grade 1 Exam

Answer:

To buy a toy car of Rs. 50, we can use either a single note of Rs. 50 or a combination of smaller denominations that add up to Rs. 50. Option (a) and (b) provide two such combinations.

(a) One note of Rs. 50:

This is the simplest and easiest way to buy the toy car. We just need to give the shopkeeper a single note of Rs. 50 and we will get the car. This method requires only one transaction and one piece of currency.

(b) Four notes of Rs. 10 and two Rs. 5 coins:

This is another way to buy the toy car. We can give the shopkeeper four notes of Rs. 10 and two coins of Rs. 5 each. This method requires five transactions (giving four notes and two coins) and six pieces of currency (four notes and two coins). However, it is still a valid way to buy the toy car.

Therefore, option (d) is the correct answer as it includes both options (a) and (b) as valid ways to buy the toy car of Rs. 50.

Counting Money in Terms of Coins

Introduction:
In India, money is counted in terms of notes and coins. While notes are used for larger denominations, coins are used for smaller denominations.

Coins:
Coins are small, round, and metallic objects that are issued by the government as a form of currency. They come in different shapes, sizes, and denominations.

Denominations:
Coins are issued in denominations of 50 paise, 1 rupee, 2 rupees, 5 rupees, and 10 rupees. The 50 paise coin is no longer in circulation and has been replaced by the 1 rupee coin.

Value:
The value of coins is determined by their denominations. For example, a 1 rupee coin has a value of 1 rupee, a 2 rupee coin has a value of 2 rupees, and so on.

Counting:
When counting coins, it is important to sort them by their denominations first. Then, they can be counted by grouping them in piles of ten. For example, ten 1 rupee coins make a pile of 10 rupees.

Conclusion:
In conclusion, coins are an important part of the Indian currency system and are used for smaller denominations. They are counted by sorting them by their denominations and grouping them in piles of ten.

Understanding the Problem
To determine how many 50 paise coins are needed to make Rs. 5, we first need to understand the relationship between paise and rupees.
Conversion of Rupees to Paise
- 1 Rupee = 100 Paise
- Therefore, Rs. 5 = 5 x 100 = 500 Paise
Value of Each Coin
- Each 50 paise coin is worth 50 Paise.
Calculating the Number of Coins
To find out how many 50 paise coins make up 500 paise, we use the following calculation:
- Total Paise Needed = 500 Paise
- Value of Each Coin = 50 Paise
Now, we divide the total paise by the value of each coin:
- Number of Coins = Total Paise / Value of Each Coin
- Number of Coins = 500 Paise / 50 Paise = 10
Conclusion
Thus, you need a total of 10 coins of 50 paise each to make Rs. 5.
The correct answer is option 'C', which signifies that 10 coins are required.

Remaining Money Calculation:
Mohan initially had 4 Rs. 5 coins, and he gave 3 of them to buy a toy. To find out how much money he is left with, we need to subtract the amount he spent from the total amount he initially had.

Calculation:
Total amount initially = 4 Rs. 5 coins = 4 * Rs. 5 = Rs. 20
Amount spent = 3 Rs. 5 coins = 3 * Rs. 5 = Rs. 15
Remaining money = Total amount initially - Amount spent = Rs. 20 - Rs. 15 = Rs. 5

Answer Explanation:
Therefore, Mohan is left with Rs. 5 after giving away 3 Rs. 5 coins to buy a toy. Hence, the correct answer is option 'D' (Rs. 5).

Understanding the Options
In this question, we are given four monetary values: Rs. 10, Rs. 30, Rs. 100, and Rs. 50. Our task is to identify the odd one out, which in this case is option 'B' (Rs. 30).
Analysis of the Options
- Rs. 10: This is a basic denomination often used in daily transactions.
- Rs. 30: This amount is not a common denomination in Indian currency. It is typically not used as a standalone bill or coin in regular transactions.
- Rs. 100: This is a widely accepted and commonly used denomination in various transactions.
- Rs. 50: Similar to Rs. 100, this is also a common bill used frequently in commerce.
Why Rs. 30 is the Odd One Out
- Non-standard Denomination: Rs. 30 does not have a dedicated bill or coin in circulation. Instead, it is usually formed by combining smaller denominations like Rs. 10 and Rs. 20 or Rs. 50 minus Rs. 20.
- Practical Usage: While Rs. 10, Rs. 50, and Rs. 100 can be easily used and accepted in transactions, Rs. 30 is less practical and less frequently encountered.
Conclusion
Thus, when considering the commonality and practical usage of currency denominations, Rs. 30 stands out as the odd one out. This analysis highlights the importance of recognizing standard denominations in currency.
