All questions of Addition for Class 6 Exam

47 is close to 50 and is 3 less. Take 3 from 5 to make 50, leaving 2. Then, 50 + 2 = 52.

Understanding the Shudh Method
The Shudh method is a straightforward approach used in arithmetic to simplify problems and find the correct answer without confusion. Let's break down the addition problem step by step.
Given Values
- 3
- 8
- 9
- 5
- 4
Step-by-Step Addition
1. Add the first two numbers:
- 3 + 8 = 11
2. Add the next number:
- 11 + 9 = 20
3. Add the fourth number:
- 20 + 5 = 25
4. Finally, add the last number:
- 25 + 4 = 29
Final Result
- The total sum is 29.
Options Analysis
- a) 27
- b) 28
- c) 29
- d) 30
Based on our calculations, the correct answer is option c) 29.
Conclusion
By following the Shudh method, we ensured that each addition step was clear and accurate, leading us directly to the correct answer. This method helps in avoiding mistakes and enhances arithmetic skills, especially for Class 6 students.

First: 3 + 2 = 5. Second: 4 + 7 = 11 (carry 1, add to 5 = 6). Third: 6 + 8 = 14 (carry 1). Adjust: 614 + 10 = 624.

Split: 45 | 23 + 37 | 68. Add: 45 + 37 = 82, 23 + 68 = 91. Combine: 8200 + 91 = 8291.

Understanding the Ten Point Circle
The Ten Point Circle is a method often used in mathematics to simplify addition and help visualize numbers. In this case, we will break down the operation 8 + 2 + 5 + 5.
Breaking Down the Calculation
1. Step 1: Start with the first two numbers
- 8 + 2 = 10
2. Step 2: Add the next number
- 10 + 5 = 15
3. Step 3: Add the last number
- 15 + 5 = 20
Conclusion
The final result of the calculation is 20.
Answer Options
- a) 18
- b) 19
- c) 20
- d) 21
The correct answer is option 'C', which is 20.
Why is this important?
Understanding how to break down numbers in addition helps develop mental math skills, making calculations easier and faster. The Ten Point Circle method enhances clarity in addition by allowing students to visualize the process step-by-step.
Practice Makes Perfect

Understanding the Problem
To solve the problem of 88 + 7 using the "Completing the Whole" method, we need to understand how to round numbers to make addition easier.
Breaking Down the Numbers
- We start with the number 88.
- The next whole number after 88 is 90.
- To reach 90, we need to add 2 to 88.
Completing the Whole
- When we add 2 to 88, we reach 90.
- Now, we have already accounted for 2 out of the 7 we need to add.
- This means we still need to add 5 (7 - 2 = 5).
Calculating the Total
- Now, we can add the completed whole:
- 90 (from 88 + 2)
- Plus the remaining 5
- So, 90 + 5 = 95.
Conclusion
Thus, the final answer to the problem 88 + 7 is 95. Therefore, the correct option is 'B'.
- This method of "Completing the Whole" simplifies addition by making it easier to visualize and calculate. It helps in breaking down numbers into manageable parts, allowing for quicker mental math.

Understanding the Problem
To compute the sum of the numbers 25, 17, 33, and 45, we will add them together step-by-step.
Step 1: Adding the First Two Numbers
- Start with the first two numbers:
25 + 17 = 42
Step 2: Adding the Next Number
- Now take the result from Step 1 and add the next number (33):
42 + 33 = 75
Step 3: Adding the Last Number
- Finally, take the result from Step 2 and add the last number (45):
75 + 45 = 120
Final Result
- The total sum of 25 + 17 + 33 + 45 is 120.
Correct Answer
- The correct answer is option 'C', which is 120.
Verification
- To ensure accuracy, let’s double-check by adding all numbers at once:
25 + 17 + 33 + 45 = 120.
Using grouping or rearranging the numbers can also help confirm the result, but the total remains consistent.
Conclusion
- Therefore, the final answer to the sum is 120, confirming that option 'C' is indeed correct.

First column: 3 + 2 = 5. Second column: 4 + 7 = 11 (carry 1, add to 5 = 6). Combine: 60 + 1 = 61.

Break 4 into 1 + 3: 19 + 1 = 20 and 7 + 3 = 10. Then, 20 + 10 = 30.

67 is 3 short of 70. Add 3 to 67 to get 70, leaving 5 from 8. Then, 70 + 5 = 75.
