If 1 is added to each odd digit and 2 is subtracted from each even digit in the number 8574162, what will be the sum of the digits which are second from the left and second from the right in the new number thus formed?
Given:
Original number = 8574162
Rules:
Add 1 to each odd digit
Subtract 2 from each even digit
Original digits (from left):
8 5 7 4 1 6 2
Apply the rules:
8 (even) → 8 – 2 = 6
5 (odd) → 5 + 1 = 6
7 (odd) → 7 + 1 = 8
4 (even) → 4 – 2 = 2
1 (odd) → 1 + 1 = 2
6 (even) → 6 – 2 = 4
2 (even) → 2 – 2 = 0
New number: 6 6 8 2 2 4 0
Now identify:
Second from left = 6
Second from right = 4
Sum = 6 + 4 = 10
Final Answer: 10
Final Correct Option: (C)
