Problem Analysis

We are given that three pigs named Nif, Nuf, and Naf were born one after another with a 4-year gap between each of them. We also know that the oldest pig is currently 5 times older than the youngest pig. We need to determine the age of the youngest pig.

Solution

Let's assign variables to represent the ages of the pigs. Let's say the age of the youngest pig is x years.

According to the given information, the age of the middle pig (Nuf) would be x + 4 years, and the age of the oldest pig (Naf) would be x + 8 years.

We are also told that the oldest pig is currently 5 times older than the youngest pig. This can be expressed as:

(x + 8) = 5x

To solve this equation, we can subtract x from both sides:

8 = 4x

Now, we can divide both sides by 4 to solve for x:

x = 2

Therefore, the youngest pig is 2 years old.

Answer

The youngest pig is 2 years old.
