Each of the digits in the number 6325894 is arranged in descending order from right to left (i.e., ascending order from left to right). Calculate the sum of the digits whose position(s) remain(s) unchanged as compared to that in the original number and the lowest digit.

This question is based on the five, three-digit numbers given below: (Left) 412 617 324 162 751 (Right) (Example: 697 - First digit = 6, second digit = 9 and third digit = 7) What will be the resultant if the second digit of the highest number is added to the first digit of the lowest number?

This question is based on the five three-digit numbers given below: (Left) 418 439 491 472 465 (Right) What will be the resultant if the third digit of the highest number is added to the third digit of the lowest number? (Note: All operations are performed from left to right.)
