8
16
10
Correct answer
16
Why this answer is correct
The logic followed here is:
Given number: 5341256
Original number: 5 3 4 1 2 5 6
| Digit | Type | Operation | New Digit |
|---|---|---|---|
| 5 | Odd | +3 = 8 | 8 |
| 3 | Odd | +3 = 6 | 6 |
| 4 | Even | −2 = 2 | 2 |
| 1 | Odd | +3 = 4 | 4 |
| 2 | Even | −2 = 0 | 0 |
| 5 | Odd | +3 = 8 | 8 |
| 6 | Even | −2 = 4 | 4 |
New number formed: 8 6 2 4 0 8 4
Now,
First digit from the left = 8
Second digit from the right = 8
Now, Sum = 8 + 8 = 16
Therefore, the sum is 16
Hence, the correct answer is Option 3.
