Х-возраст сына
7х-семикратное значение возраста сына
3х-возраст отца
6х-возраст деда
7х+3х+6х=192
16х=192
х=192/16
х=12-возраст сына
6*12=72-возраст деда

Answer 2

Problem Analysis

We are given the following information: - The father is 3 times older than the son. - The grandfather is 6 times older than the grandson. - The sum of the ages of the son, father, and grandfather is equal to 192.

We need to determine the age of the grandfather.

Solution

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

According to the given information: - The age of the father is 3 times the age of the son, so the age of the father is 3x years. - The age of the grandfather is 6 times the age of the grandson, so the age of the grandfather is 6x years.

The sum of their ages is equal to 192: x + 3x + 6x = 192

Simplifying the equation: 10x = 192

Dividing both sides of the equation by 10: x = 19.2

Since we are dealing with ages, we can round down the age of the son to the nearest whole number: x = 19

Now, we can calculate the age of the grandfather: Age of the grandfather = 6x = 6 * 19 = 114 years

Therefore, the age of the grandfather is 114 years.

Answer

The age of the grandfather is 114 years.
