Question

Отец и мать имеют столько же сыновей, сколько и дочерей, а у их сыновей вдвое меньше братьев, чем сестер. Сколько женщин в этой семье?

Answer 1

столько же сколько мужчин

Answer 2

Solution:

To solve this problem, we can use a system of equations to represent the given information and then solve for the number of women in the family.

Let's denote the number of sons as S and the number of daughters as D. We are given the following information: 1. The father and mother have the same number of sons as daughters: S = D. 2. The sons have half as many brothers as sisters: S - 1 = (D - 1) / 2.

Step 1: Express the Given Information in Equations

Using the given information, we can express the two conditions as equations: 1. S = D 2. S - 1 = (D - 1) / 2

Step 2: Solve for the Number of Women

We can solve the system of equations to find the number of women in the family.

Step 3: Solution

Let's solve the system of equations to find the number of women in the family.

From equation (1), we have S = D. Substituting this into equation (2), we get: S - 1 = (S - 1) / 2

Solving for S, we find: S = 3

Since S = D, the number of daughters is also 3.

Conclusion:

There are 3 women in this family.
