Answer 2

Solution:

Let's solve this step by step.

1. Let's denote Dima's age as D, his mother's age as M, and his father's age as P.

2. We are given the following information: - Dima and his mother together are 40 years old: D + M = 40. - Dima and his father together are 42 years old: D + P = 42. - Dima, his mother, and his father together are 74 years old: D + M + P = 74.

3. We can solve these equations simultaneously to find the ages of Dima, his mother, and his father.

Calculation:

Using the given information, we can solve for the ages of Dima, his mother, and his father.

Adding the first two equations, we get: 2D + M + P = 82.

Subtracting the third equation from this sum, we get: D = 8.

Substituting D = 8 into the first equation, we get: M = 32.

Substituting D = 8 into the second equation, we get: P = 34.

Answer:

So, the ages are: - Dima is 8 years old. - His mother is 32 years old. - His father is 34 years old.
