Question

к некоторому числу прибавили сумму его цифр после чего получилось число 80.чему было равно исходное число

Answer 1

Problem Analysis

We are given that a certain number is increased by the sum of its digits, resulting in the number 80. We need to find the original number.

Solution

Let's assume the original number is represented by the variable x. We can break down x into its individual digits and calculate their sum. Then, we can add this sum to x and check if it equals 80. If it does, we have found the original number.

To solve this problem, we can follow these steps: 1. Initialize a variable sum_digits to 0. 2. Convert the number x to a string to easily access its individual digits. 3. Iterate over each digit in the string representation of x. 4. Convert each digit back to an integer and add it to sum_digits. 5. Add sum_digits to x and check if the result is equal to 80. 6. If the result is equal to 80, the original number is x. Otherwise, there is no solution.

Let's implement this solution in Python:

def find_original_number():
    for x in range(1, 100):
        sum_digits = 0
        for digit in str(x):
            sum_digits += int(digit)
        if x + sum_digits == 80:
            return x
    return None

original_number = find_original_number()
print("The original number is:", original_number)

Running this code will output the original number that satisfies the given condition.

Answer

The original number that, when increased by the sum of its digits, results in 80 is 29.
