Understanding the Total Votes Polled
In the given election scenario, a total of 27,895 votes were cast. This number includes both valid and invalid votes.
Identifying Invalid Votes
Among the total votes, 6,521 were identified as invalid. These are votes that could not be counted towards the final tally due to reasons such as being improperly filled out or not meeting voting requirements.
Calculating Valid Votes
To determine the number of valid votes, we need to subtract the invalid votes from the total votes.
Mathematical Calculation
- Total Votes: 27,895
- Invalid Votes: 6,521
Now, perform the subtraction:
- Valid Votes = Total Votes - Invalid Votes
- Valid Votes = 27,895 - 6,521
After performing the calculation, we find:
- Valid Votes = 21,374
Conclusion
The valid votes cast in the election amount to 21,374. Therefore, the correct answer is option 'C', which states that the number of valid votes is 21,374.
This calculation is crucial for determining the outcome of the election and understanding voter participation.

Sudhir Mehta answered |
Answer is 1096642
3 x + y so 3 × 545498 = 1636494
x is 5646 more than y
So, 545498 - 5646 = 539852
Hence, 1636494 - 539852 = 1096642
3 x + y so 3 × 545498 = 1636494
x is 5646 more than y
So, 545498 - 5646 = 539852
Hence, 1636494 - 539852 = 1096642

To find out how many bags of cat food were left after customers bought some, follow these steps:
Initial number of bags: 534
Bags bought by customers: 145
Subtract the number of bags bought from the initial number of bags:
534 - 145 = 389
So, the number of bags left is 389.
The correct answer is: C: 389
Initial number of bags: 534
Bags bought by customers: 145
Subtract the number of bags bought from the initial number of bags:
534 - 145 = 389
So, the number of bags left is 389.
The correct answer is: C: 389

- Now, 10 - 3 = 7.
- Step 3: Move to the next column:
- 9 (after borrowing) - 5 = 4.
- Step 4: Move to the next column:
- 9 - 7 = 2.
- Step 5: Finally, for the leftmost column:

Edu Impact answered |
To solve 21587 - 10479:
- Start with the units place: 7 - 9. Since 7 < 9, borrow 1 from the tens place, making it 17 - 9 = 8.
- Move to the tens place: 7 (after borrowing) - 7 = 0.
- Hundreds place: 5 - 4 = 1.
- Thousands place: 1 - 0 = 1.
- Ten-thousands place: 2 - 1 = 1.
Therefore, 21587 - 10479 = 11108, which matches option A.

- Subtracting zero removes nothing, so n – 0 = n.
- This follows the identity property of subtraction.
- For instance, 8 – 0 = 8.
- Therefore, the result is the number itself.
