All questions of Addition for Class 6 Exam

5+5 = 10 and 8+2=10. So, 10+10= 20 that's why c is the correct answer.

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

Understanding the Multiple of Ten Method
The Multiple of Ten method is a simple strategy to perform addition by rounding numbers to the nearest ten, making calculations easier. Let’s break down how to apply this method for the problem 67 + 8.
Step 1: Round to the Nearest Ten
- Identify the Base Number: Here, we need to add 8 to 67.
- Choose the Nearest Ten: The nearest ten to 67 is 70.
Step 2: Calculate the Difference
- Subtract to Find the Difference: To use the rounded number, we need to find out how much we increased it by:
- 70 (rounded number) - 67 (original number) = 3.
Step 3: Adjust the Addition
- Perform the Addition: Now, instead of adding 8 directly to 67, we add it to our rounded number (70) and then subtract the difference we calculated:
- 70 + 8 = 78.
- Adjust for the Difference: Finally, we subtract the difference (3) that we added to round up:
- 78 - 3 = 75.
Final Result
- The result of 67 + 8 using this method is 75.
Answer Choices Review
- a) 74 - Too low
- b) 75 - Correct
- c) 76 - Too high
- d) 77 - Too high
Thus, the correct answer is option 'B', which is 75. This method not only simplifies the calculation but also helps in quickly determining the answer without complicated steps.

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.

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

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

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.

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