If the first and third digits of each number are inter changed and one...
Explanation:

To find the pair of numbers with the highest total numerical value, we need to follow the given instructions.

Step 1: Interchange the first and third digits of each number.

For example, for the numbers 946 and 728, the digit interchange would be:

946 -> 649
728 -> 827

Step 2: Add one to the second digit of each number.

For example, for the numbers 649 and 827, adding one to the second digit would be:

649 -> 659
827 -> 837

Step 3: Calculate the numerical value of each number.

For example, the numerical values of 659 and 837 are:

659 = (6 * 100) + (5 * 10) + 9 = 600 + 50 + 9 = 659
837 = (8 * 100) + (3 * 10) + 7 = 800 + 30 + 7 = 837

Step 4: Compare the total numerical values of the pairs of numbers.

For example, for the given pairs:

a) 946 and 728: Total numerical value = 659 + 837 = 1496
b) 728 and 574: Total numerical value = 837 + 475 = 1312
c) 669 and 946: Total numerical value = 696 + 649 = 1345
d) 669 and 629: Total numerical value = 696 + 296 = 992

Conclusion:

From the calculations, we can see that the pair of numbers 669 and 629 has the highest total numerical value of 992. Therefore, the correct answer is option 'D'.
