If 2 is added to each odd digit and 2 is subtracted from each even digit in the number 6127385, then which of the following digits will be third from the right?​

Given: 6127385

Add 2 to each odd digit and subtract 2 from each even digit.

6 is even → 6 - 2 = 4

1 is odd → 1 + 2 = 3

2 is even → 2 - 2 = 0

7 is odd → 7 + 2 = 9

3 is odd → 3 + 2 = 5

8 is even → 8 - 2 = 6

5 is odd → 5 + 2 = 7

The new number becomes: 4 3 0 9 5 6 7

Now, count the digits from the right:

So, 3rd from right is: 5

Thus, correct option is (b).
