Question 2. Match the big bag with small bag.
Answer: Each big bag contains a total amount that can be formed by adding or subtracting the amounts in the small bags. Here are the correct matches:
1. The big bag with Rs 50 matches the small bags containing Rs 32 + Rs 16 + Rs 2.
2. The big bag with Rs 73 matches the small bags containing Rs 123 - Rs 33 - Rs 17.
3. The big bag with Rs 517 matches the small bags containing Rs 575 - Rs 38 - Rs 20.
4. The big bag with Rs 796 matches the small bags containing Rs 489 + Rs 258 + Rs 49.
In simple words: We connect the big money bag to the small money bags that add up to its value, or whose difference equals its value. This helps us see different ways to make the same amount of money.

🎯 Exam Tip: Carefully add and subtract the values in the small bags to ensure they exactly match the value in the big bag. Double-check your calculations.

Question 3. Divide 1000 paise equally for 5 students. How many rupees does each student get?
Answer: First, we find out how many paise each student gets.
Total paise = 1000
Number of students = 5
Paise each student gets = 1000 \( \div \) 5 = 200 paise
Next, we convert 200 paise into rupees.
We know that 100 paise = Rs 1.
So, 200 paise = \( \frac{200}{100} \) rupees = Rs 2
Therefore, each student gets Rs 2. Distributing money equally requires careful division and conversion.
In simple words: If you share 1000 paise among 5 friends, each friend gets 200 paise. This is the same as getting 2 rupees each.

🎯 Exam Tip: Always remember to convert paise to rupees by dividing by 100 after you've completed any calculations in paise, if the question asks for the answer in rupees.

Question 4. Find out how many denominations of Rs 1, Rs 2, Rs 5, Rs 10, Rs 20, Rs 50, Rs 100, Rs 200, Rs 500, and Rs 2,000 are there in Rs 10,000?
Answer: To make Rs 10,000 using different denominations, here are the counts for each:
1. Rs 1 x 10,000 = Rs 10,000
2. Rs 2 x 5,000 = Rs 10,000
3. Rs 5 x 2,000 = Rs 10,000
4. Rs 10 x 1,000 = Rs 10,000
5. Rs 20 x 500 = Rs 10,000
6. Rs 50 x 200 = Rs 10,000
7. Rs 100 x 100 = Rs 10,000
8. Rs 200 x 50 = Rs 10,000
9. Rs 500 x 20 = Rs 10,000
10. Rs 2,000 x 5 = Rs 10,000
This shows there are many different ways to achieve a total of Rs 10,000 using various combinations of currency notes. Understanding denominations helps in handling money efficiently.
In simple words: We can make Rs 10,000 by using different numbers of notes for each value. For example, you can use 10,000 notes of Rs 1, or 5 notes of Rs 2,000, and so on.

🎯 Exam Tip: When dealing with denominations, remember that the total value is found by multiplying the number of notes by the value of each note.
