Directions (75-79): Read the given number series carefully to answer the related questions:

692    318    196     486 7   54

If we arranged all digits in descending order within the number than which of the following is 2nd highest?

The correct option is 196.

Let us analyze the given number series step-by-step: 692, 318, 196, 486, 754.

Step 1: Arrange the digits of each number in descending order within the number:
- For 692: Digits are 6, 9, 2. Arranged in descending order: 962
- For 318: Digits are 3, 1, 8. Arranged in descending order: 831
- For 196: Digits are 1, 9, 6. Arranged in descending order: 961
- For 486: Digits are 4, 8, 6. Arranged in descending order: 864
- For 754: Digits are 7, 5, 4. Arranged in descending order: 754

Step 2: Find the second highest number among the newly formed numbers:
Let us arrange the newly formed numbers in descending order:
$962>961>864>831>754$

From the ordered list:
- The highest number is 962 (formed from 692).
- The 2nd highest number is 961 (formed from 196).

Therefore, the number which becomes the second highest is 196.
