Answer 1

Отец старше сына на 27 лет . А через 4 года он будет старше в 4 раза . Сколько лет сыну и отцу.

x- возраст отца, (x-27 ) - возраст сына.
(x+4)=4(x-27+4) через 4 года.

4+4·23=3x     x=32  - возраст отца, 32-27=5 - возраст сына

Answer 2

Problem Analysis

We are given that the father is 27 years older than the son, and in 4 years, the father will be 4 times older than the son. We need to determine the ages of the son and the father.

Solution

Let's assume the current age of the son is x years.

According to the given information, the current age of the father is x + 27 years.

In 4 years, the son's age will be x + 4 years, and the father's age will be x + 27 + 4 years.

According to the second part of the information, the father's age in 4 years will be 4 times the son's age in 4 years. Mathematically, we can represent this as:

x + 27 + 4 = 4(x + 4)

Now, let's solve this equation to find the value of x.

x + 27 + 4 = 4x + 16

Simplifying the equation:

3x = 15

x = 5

Therefore, the current age of the son is 5 years.

The current age of the father can be calculated as x + 27 = 5 + 27 = 32 years.

Answer

The son is currently 5 years old, and the father is currently 32 years old.
