If 2 is added to each even digit and 2 is added to each odd digit in the number 7153246, what will be the sum of all the odd digits in the new number thus formed?​

Given the number: 7153246
As per the question 
Add 2 to each digit (whether even or odd)
7 → 7 + 2 = 9 (odd)
1 → 1 + 2 = 3 (odd)
5 → 5 + 2 = 7 (odd)
3 → 3 + 2 = 5 (odd)
2 → 2 + 2 = 4 (even)
4 → 4 + 2 = 6 (even)
6 → 6 + 2 = 8 (even)
New number = 9375468
Now extract odd digits:
9, 3, 7, 5
Sum = 9 + 3 + 7 + 5 = 24

Correct answer is (d) 24.
