If 2 is added to each odd digit and 1 is subtracted from each even digit in the number 34135278, what will be the sum of the digits that are third from the Left and third from the right?

Explanation

To solve this, let’s apply the transformation to each digit in the number 34135278: Identify odd and even digits: Odd digits: 3, 1, 3, 5, 7 Even digits: 4, 2, 8 Apply the transformations: For odd digits: add 2 For even digits: subtract 1 Transform each digit: 3 (odd) → 3+2=53 + 2 = 53+2=5 4 (even) → 4−1=34 - 1 = 34−1=3 1 (odd) → 1+2=31 + 2 = 31+2=3 3 (odd) → 3+2=53 + 2 = 53+2=5 5 (odd) → 5+2=75 + 2 = 75+2=7 2 (even) → 2−1=12 - 1 = 12−1=1 7 (odd) → 7+2=97 + 2 = 97+2=9 8 (even) → 8−1=78 - 1 = 78−1=7 Identify the third digit from the left and third from the right: Third from the left: 3 Third from the right: 1 Calculate the sum of these two digits: 1. 3+1=43 + 1 = 43+1=4 Answer: The sum of the digits that are third from the left and third from the right is 4.
