If 1 is subtracted from each odd digit and 1 is added to each even digit in the number 843675432925 what will be the sum of the digits which are third from the left and second from the right in the new number thus formed?
5
Original number: 8 4 3 6 7 5 4 3 2 9 2 5
Odd digits (3, 7, 5, 3, 9, 5) are reduced by 1; even digits (8, 4, 6, 4, 2, 2) are increased by 1.
New number: 9 5 2 7 6 4 5 2 3 8 3 4
Third digit from the left = 2; second digit from the right = 3.
Sum = 2 + 3 = 5
Hence, 5.
