Detailed Solution & Logic
Correct Answer:
6
Given number: 4813576
Rule:
- Add 1 to each odd digit
- Subtract 2 from each even digit
Change each digit:

| 8 | 8 − 2 | 6 |
| 1 | 1 + 1 | 2 |
| 3 | 3 + 1 | 4 |

| 7 | 7 + 1 | 8 |
| 6 | 6 − 2 | 4 |
New number = 2624684
Now:
- Highest digit = 8
- Lowest digit = 2
Difference = 8 − 2 = 6
Answer: 6
