Question

Дедушка старше внука в 6 раз а внук моложе сваего отца в 3 раза . вместе им тром 100 лет . сколько лет отцу сыну и дедушке.

Answer 1

Внук - x
тогда дедушка - 6х
отец - 3х
Вместе им 100 лет
значит: х+6х+3х=100
10х=100
x=10 лет внуку
Отцу 3х=3*10=30 лет
Деду 6х=6*10=60 лет
вроде так

Answer 2

Problem Analysis

We are given that the grandfather is 6 times older than the grandson, and the grandson is 3 times younger than his father. The sum of their ages is 100 years. We need to determine the ages of the father, son, and grandfather.

Solution

Let's assume the age of the grandson is x years. According to the given information, the age of the grandfather is 6 times that of the grandson, so the age of the grandfather is 6x years.

The age of the grandson is also 3 times younger than his father, so the age of the father is 3 times that of the grandson, which is 3x years.

The sum of their ages is 100 years, so we can write the equation:

x + 6x + 3x = 100

Simplifying the equation:

10x = 100

Dividing both sides by 10:

x = 10

Therefore, the age of the grandson is 10 years.

To find the ages of the father and grandfather, we substitute the value of x back into the equations:

Age of the father = 3x = 3 * 10 = 30 years

Age of the grandfather = 6x = 6 * 10 = 60 years

So, the father is 30 years old and the grandfather is 60 years old.

Answer

The father is 30 years old, the son is 10 years old, and the grandfather is 60 years old.
