Number Transformation Process
The task involves modifying the digits of the number \(2741586\) based on whether they are odd or even.
- Rule for Odd Digits: Add 2.
- Rule for Even Digits: Subtract 1.
Applying the Digit Rules
Let's process each digit of the number \(2741586\):
- Digit \(2\) (Even): \(2 - 1 = 1\)
- Digit \(7\) (Odd): \(7 + 2 = 9\)
- Digit \(4\) (Even): \(4 - 1 = 3\)
- Digit \(1\) (Odd): \(1 + 2 = 3\)
- Digit \(5\) (Odd): \(5 + 2 = 7\)
- Digit \(8\) (Even): \(8 - 1 = 7\)
- Digit \(6\) (Even): \(6 - 1 = 5\)
Forming the New Number
Construct the new number using the transformed digits in their original order:
Original Number: \(2 7 4 1 5 8 6\)
New Number: \(1 9 3 3 7 7 5\)
Counting Repeated Digits
Now, we count the occurrences of each digit in the new number \(1933775\) to find digits that appear more than once:
Digits present: \(1, 9, 3, 3, 7, 7, 5\)
- Digit \(1\) appears 1 time.
- Digit \(9\) appears 1 time.
- Digit \(3\) appears 2 times.
- Digit \(7\) appears 2 times.
- Digit \(5\) appears 1 time.
The digits that appear more than once are \(3\) and \(7\).
Final Count
There are two distinct digits (\(3\) and \(7\)) that appear more than once in the new number.
Therefore, the correct answer is Two.
