If all the digit in each of the numbers are arranged in descending order within the number then, which of the following will be the highest number in the new arrangement of numbers?

The correct answer is 619.

Step-by-step Explanation:

We are given the following set of numbers: 453, 372, 574, 619.

We need to arrange the digits of each number in descending order (from highest to lowest) within the number itself and then find which resulting number is the highest.

Step 1: Rearrange the digits of each number in descending order:

• For 453: The digits are 4, 5, and 3. Arranging them in descending order gives 543.

• For 372: The digits are 3, 7, and 2. Arranging them in descending order gives 732.

• For 574: The digits are 5, 7, and 4. Arranging them in descending order gives 754.

• For 619: The digits are 6, 1, and 9. Arranging them in descending order gives 961.

Step 2: Compare the newly formed numbers:

The new set of numbers obtained is: 543, 732, 754, 961.

Comparing these numbers, the highest number in the new arrangement is 961.

Step 3: Identify the original number:

961 corresponds to the original number 619.

Therefore, 619 will be the highest number in the new arrangement.
