Problem Analysis

We are given that Arif, Namik, and Anar have been together for 47 years. Arif is 3 years older than Namik, and Anar is 2 years older than Namik. We need to determine Anar's age.

Solution

Let's assume Namik's age is x years.

According to the given information: - Arif's age = Namik's age + 3 - Anar's age = Namik's age + 2

We can set up the following equations: 1. Arif's age + Namik's age + Anar's age = 47 2. Arif's age = Namik's age + 3 3. Anar's age = Namik's age + 2

Substituting the values from equations 2 and 3 into equation 1, we get: (Namik's age + 3) + Namik's age + (Namik's age + 2) = 47

Simplifying the equation: 3Namik's age + 5 = 47 3Namik's age = 42 Namik's age = 14

Therefore, Namik is 14 years old.

To find Anar's age, we substitute Namik's age into equation 3: Anar's age = 14 + 2 = 16

Therefore, Anar is 16 years old.

Answer

Anar is 16 years old (Option B).
