To solve this question, we need to follow the given rules of increasing and decreasing the first letter of each number. Let's go step by step to find the second digit of the second highest number.
Step 1: Increase odd number of first letter by 1 and decrease even number of first letter by 1.
- 456: The first letter is an even number, so we decrease it by 1, which gives us 356.
- 789: The first letter is an odd number, so we increase it by 1, which gives us 899.
- 145: The first letter is an odd number, so we increase it by 1, which gives us 245.
- 392: The first letter is an odd number, so we increase it by 1, which gives us 492.
- 140: The first letter is an even number, so we decrease it by 1, which gives us 040.
- 653: The first letter is an odd number, so we increase it by 1, which gives us 753.
- 806: The first letter is an even number, so we decrease it by 1, which gives us 706.
Step 2: Arrange the numbers in descending order.
- 899
- 753
- 706
- 492
- 356
- 245
- 040
