Write the successor of:
21,29,999

Answer

To find the successor of the number 21,29,999, we follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition of Successor**: The successor of a number is the number that comes immediately after it. To find the successor, we simply add 1 to the given number.

2. **Write the Given Number**: The number we need to find the successor for is 21,29,999.

3. **Add 1 to the Given Number**:
- Start from the rightmost digit of 21,29,999 and add 1.
- 9 (the last digit) + 1 = 10. We write down 0 and carry over 1 to the next digit.

4. **Continue Adding with Carry**:
- Move to the next digit (the second 9). Now, add 1 (from the carry) to 9:
- 9 + 1 = 10. Again, write down 0 and carry over 1.
- Move to the next digit (the third 9). Add 1 (from the carry) to 9:
- 9 + 1 = 10. Write down 0 and carry over 1.
- Move to the next digit (the 2). Add 1 (from the carry) to 2:
- 2 + 1 = 3. Write down 3.
- The next digit (the 1) remains unchanged since there is no carry over.

5. **Write Down the Result**: After processing all digits, we find that the successor of 21,29,999 is 21,30,000.

### Final Answer:
The successor of 21,29,999 is **21,30,000**.
