If second digit will be interchanged with third digit in each number, then which number will be the second highest number after rearrangement?

Correct Answer: 574

To find which number will be the second highest number after rearranging the digits, let us perform the digit interchange step-by-step for each given number.

Step 1: Identify the original numbers
The numbers given in the options are: 453, 619, 574, and 372.

Step 2: Interchange the second digit with the third digit in each number

• For 453:
1st digit = 4, 2nd digit = 5, 3rd digit = 3
Interchanging 2nd and 3rd digits gives: 435

• For 619:
1st digit = 6, 2nd digit = 1, 3rd digit = 9
Interchanging 2nd and 3rd digits gives: 691

• For 574:
1st digit = 5, 2nd digit = 7, 3rd digit = 4
Interchanging 2nd and 3rd digits gives: 547

• For 372:
1st digit = 3, 2nd digit = 7, 3rd digit = 2
Interchanging 2nd and 3rd digits gives: 327

Step 3: Compare the new numbers
The new numbers obtained after rearrangement are: 435, 691, 547, 327.

Arranging these new numbers in descending order (highest to lowest):
691 > 547 > 435 > 327

• Highest number = 691
• Second highest number = 547

Step 4: Find the original number
The new number 547 corresponds to the original number 574.

Thus, after interchanging the second and third digits, the second highest number is 574.
