What is the difference between 2nd digit of highest number and 3rd digit of 4th lowest number?

To find the difference between the 2nd digit of the highest number and the 3rd digit of the 4th lowest number, we will analyze the given series step-by-step.

The given number series is:
692, 318, 196, 486, 754 (Note: The number 486 7 54 in the question is parsed as 486 and 754 based on standard series patterns).

Step 1: Identify the highest number.
Comparing the numbers in the series: 692, 318, 196, 486, 754.
The highest number is 754.
The 2nd digit of this highest number (754) is 5.

Step 2: Identify the 4th lowest number.
Let us arrange the numbers in ascending order (from lowest to highest):
1. 196 (1st lowest)
2. 318 (2nd lowest)
3. 486 (3rd lowest)
4. 692 (4th lowest)
5. 754 (5th lowest / highest)
The 4th lowest number is 692.
The 3rd digit of 692 is 2.

Step 3: Calculate the difference.
Difference = 2nd digit of highest number - 3rd digit of 4th lowest number
Difference = 5 - 2 = 3.

Therefore, the correct option is 3.
