If 1 is added to each odd digit and 1 is subtracted from each even digit in the number 58132745 , what will be the sum of the digits which are second from the left and third from the right?

We are given the number 58132745, and we need to modify its digits based on the following rule:

If the digit is odd, we add 1 to it.

If the digit is even, we subtract 1 from it.

5 is odd, so add 1: 5+1=6

8 is even, so subtract 1: 8−1=7

1 is odd, so add 1: 1+1=2

3 is odd, so add 1: 3+1=4

2 is even, so subtract 1: 2−1=1

7 is odd, so add 1: 7+1=8

4 is even, so subtract 1: 4−1=3

5 is odd, so add 1: 5+1=6

So, the modified number is: 67241836

Second digit from the left = 7

Third digit from the right = 8

Sum of 7 and 8 

7 + 8 = 15
