Question

Отец старше сына на 20 лет, а сын моложе отца в 5 раз. Сколько лет отцу и сколько лет сыну?

Answer 1

Допустим, что сыну х лет, тогда отцу 5х или (х+20) лет

согласно этим данным составляем уравнение:

х+20=5х

5х-х=20

4х=20

х=20:4

х=5 (лет) - сыну.

5х=5·5=25 (лет) - отцу.

Ответ: сыну 5 лет, а отцу 25 лет.

Answer 2

20+5=25лет (отцу)

25/5=5лет (сыну)

Адказ: 25, 5.

 

Answer 3

Problem Analysis

We are given that the father is 20 years older than the son and that the son is younger than the father by a factor of 5. We need to determine the ages of the father and the son.

Solution

Let's assume the son's age is x years. According to the given information, the father's age is x + 20 years.

We are also given that the son is younger than the father by a factor of 5. This means that the father's age is 5 times the son's age:

x + 20 = 5x

Simplifying the equation, we get:

4x = 20

Dividing both sides of the equation by 4, we find:

x = 5

Therefore, the son is 5 years old. Substituting this value back into the equation, we find that the father is:

x + 20 = 5 + 20 = 25 years old

So, the father is 25 years old and the son is 5 years old.

Answer

The father is 25 years old and the son is 5 years old.
