If 1 is added to each even digit and 2 is subtracted from each odd digit in the number 2756493, then which of the following digits will be second from the left in the new number thus formed?​

Given: 2756493

Add 1 to each even digit and subtract 2 from each odd digit.

2 → even → 2 + 1 = 3

7 → odd → 7 − 2 = 5

5 → odd → 5 − 2 = 3

6 → even → 6 + 1 = 7

4 → even → 4 + 1 = 5

9 → odd → 9 − 2 = 7

3 → odd → 3 − 2 = 1

The new number is: 3537571

Second digit from the left is: 5

So, 5 will be second from the left in the new number thus formed.

Thus, correct option is (b).
