Answer 2

Problem Analysis

We are given the information that the grandfather is 11 times older than his grandson currently, and in 6 years, he will be 5 times older than his grandson. We need to determine the current age of the grandfather.

Solution

Let's assume the current age of the grandson is x years. According to the given information, the current age of the grandfather is 11x years.

In 6 years, the grandson will be x + 6 years old, and the grandfather will be 11x + 6 years old. At that time, the grandfather will be 5 times older than the grandson. Therefore, we can write the following equation:

11x + 6 = 5(x + 6)

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

11x + 6 = 5x + 30

Subtracting 5x from both sides:

6x + 6 = 30

Subtracting 6 from both sides:

6x = 24

Dividing both sides by 6:

x = 4

Therefore, the current age of the grandson is 4 years. To find the current age of the grandfather, we multiply the grandson's age by 11:

Grandfather's age = 11 * 4 = 44 years

So, the current age of the grandfather is 44 years.

Answer

The current age of the grandfather is 44 years.
