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 to find the second highest number after rearranging the digits within each number in descending order.

The given numbers in the series are:
692, 318, 196, 486, 754

Note: The input data lists "486 7 54", which when correlated with the options represents the two numbers 486 and 754.

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

Step 2: Compare the newly formed numbers
The new set of numbers obtained is:
962, 831, 961, 864, 754

Arranging these new numbers in descending order to identify their ranks:
1st Highest: 962 (from original number 692)
2nd Highest: 961 (from original number 196)
3rd Highest: 864 (from original number 486)
4th Highest: 831 (from original number 318)
5th Highest: 754 (from original number 754)

Therefore, the number which becomes the second highest after the rearrangement is 961, which corresponds to the original number 196.
