If 2 is added to each odd digit and 1 is subtracted from each even digit in the number 7481652, what will be the difference between the first digit from the left and the first digit from the right in the new number thus formed?​

Given number: 7481652

Add 2 to odd digits

Subtract 1 from even digits

7 → 7 + 2 = 9

4 → 4 - 1 = 3

8 → 8 - 1 = 7

1 → 1 + 2 = 3

6 → 6 - 1 = 5

5 → 5 + 2 = 7

2 → 2 - 1 = 1

New number: 9373571

First digit (from left) = 9

First digit (from right) = 1

Difference = 9 - 1 = 8

Thus, correct option is (d).
