If we increase each even digit by '1' and decrease each odd digit by '1' in the number '7846921453' and then arrange all the number in aescending order, then what is the sum of the last five digits from the right end after the rearrangement?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 35.
Given number: 7846921453
Even digit + 1; Odd digit - 1
7846921453 → 6957830542
Now arrange all the number in aescending order,
6957830542 → 0234556789
Thus, the sum of the last five digits from the right end = 5 + 6 + 7 + 8 + 9 = 35
