Test: Digit Sum Method - Class 6 MCQ

To find the digital sum, we need to add up all the individual digits of the number. For 124, the sum of its digits is 1 + 2 + 4 = 7, which is not an option in the given choices. Therefore, the correct answer is .

Adding up the individual digits of 38, we get 3 + 8 = 11. However, since we are looking for the digital sum, we further add the digits of 11: 1 + 1 = 2. Therefore, the correct answer is 2, which is option a.

The sum of the digits of 496 is 4 + 9 + 6 = 19. Therefore, the correct answer is option b.

Adding up the digits of 9876, we get 9 + 8 + 7 + 6 = 30. However, since we are looking for the digital sum, we further add the digits of 30: 3 + 0 = 3. Therefore, the correct answer is 30, which is option a.

The sum of the digits of 339 is 3 + 3 + 9 = 15. Therefore, the correct answer is option c.

Adding the numbers 6541 and 843, we get 7384. Now, let's calculate the digital sum of 7384: 7 + 3 + 8 + 4 = 22. Since we are looking for a single-digit digital sum, we add the digits of 22: 2 + 2 = 4. Therefore, the correct answer is option a) 7384.

Adding the numbers 873 and 4466, we get 5339. The digital sum of 5339 is calculated as 5 + 3 + 3 + 9 = 20. Since we need a single-digit digital sum, we add the digits of 20: 2 + 0 = 2. Therefore, the correct answer is option a) 5339.

Adding the numbers 1930 and 6196, we get 8126. The digital sum of 8126 is calculated as 8 + 1 + 2 + 6 = 17. Since we need a single-digit digital sum, we add the digits of 17: 1 + 7 = 8. Therefore, the correct answer is option a) 8126.

Adding the numbers 9670 and 398, we get 10068. The digital sum of 10068 is calculated as 1 + 0 + 0 + 6 + 8 = 15. Since we need a single-digit digital sum, we add the digits of 15: 1 + 5 = 6. Therefore, the correct answer is option b) 10088.

Adding the numbers 4943 and 862, we get 5805. The digital sum of 5805 is calculated as 5 + 8 + 0 + 5 = 18. Since we need a single-digit digital sum, we add the digits of 18: 1 + 8 = 9. Therefore, the correct answer is option b) 5805
