Follow these steps to find the sum of repeated digits:
Original Number Analysis
The original number given is 97145286.
Identifying Even Digits
First, identify the even digits in the number 97145286. The even digits are 4, 2, 8, and 6.
Digit Transformation
Next, subtract 1 from each of these identified even digits:
- $4 - 1 = 3$
- $2 - 1 = 1$
- $8 - 1 = 7$
- $6 - 1 = 5$
Forming the New Number
Now, replace the original even digits (4, 2, 8, 6) with their new values (3, 1, 7, 5) in the number 97145286:
- Original: 9 7 1 4 5 2 8 6
- New: 9 7 1 3 5 1 7 5
The new number formed is 97135175.
Finding Repeated Digits
Examine the digits in the new number 97135175 to find which ones appear more than once:
- The digit 9 appears once.
- The digit 7 appears twice.
- The digit 1 appears twice.
- The digit 3 appears once.
- The digit 5 appears twice.
The digits repeated more than once are 7, 1, and 5.
Calculating the Sum
Finally, calculate the sum of these repeated digits:
Sum = $7 + 1 + 5 = 13$.
