If 3 is added to each even digit and 2 is added to each odd digit in the number 413257, what will be the sum of the first and last digits in the new number thus formed?​

Given: 413257

Even digits: Add 3 and Odd digits: Add 2

4 → even → 4 + 3 = 7

1 → odd → 1 + 2 = 3

3 → odd → 3 + 2 = 5

2 → even → 2 + 3 = 5

5 → odd → 5 + 2 = 7

7 → odd → 7 + 2 = 9

New number formed: 735579

First digit = 7

Last digit = 9

Sum = 7 + 9 = 16

So, 16 will be the sum of the first and last digits in the new number thus formed.

Thus, correct option is (d).
