Question

If 1 is added to each even digit and 2 is subtracted from each odd digit in the number 9368547, what will be the sum of the digits which are third from the left and third from the right in the new number thus formed?​

A.

8

B.

10

C.

14

D.

12

Correct option is B

Given:
Number: 9368547
Logic:
Even digit → +1
Odd digit → –2
Original → New:
9 (odd) → 9 – 2 = 7
3 (odd) → 3 – 2 = 1
6 (even) → 6 + 1 = 7
8 (even) → 8 + 1 = 9
5 (odd) → 5 – 2 = 3
4 (even) → 4 + 1 = 5
7 (odd) → 7 – 2 = 5
New number formed: 7179355
Third from left = 7
Third from right = 3
Sum = 7 + 3 = 10
Thus, correct option is (b).
