Answer 2

Problem Analysis

We are given the ages of Anton, his sister Nastya, and their mother. We need to determine the age of each person.

Solution

Let's assign variables to the ages of Anton, Nastya, and their mother: - Anton's age: A - Nastya's age: N - Mother's age: M

We are given the following information: 1. Anton and his mother are 43 years old together: A + M = 43. 2. Nastya and her mother are 40 years old together: N + M = 40. 3. All three of them together are 50 years old: A + N + M = 50.

We can solve this system of equations to find the values of A, N, and M.

From equation 1, we can express A in terms of M: A = 43 - M. From equation 2, we can express N in terms of M: N = 40 - M.

Substituting these expressions into equation 3, we get: (43 - M) + (40 - M) + M = 50.

Simplifying the equation: 83 - M = 50. M = 83 - 50 = 33.

Now that we have the value of M, we can substitute it back into equations 1 and 2 to find the values of A and N: A = 43 - M = 43 - 33 = 10. N = 40 - M = 40 - 33 = 7.

Therefore, Anton is 10 years old, Nastya is 7 years old, and their mother is 33 years old.

Answer

Anton is 10 years old, Nastya is 7 years old, and their mother is 33 years old.
