Answer 1

Step-by-step explanation:

A) 29 years old

your correct answer

Answer 2

Answer:

Let the age of Yasir be = x years. Then the age of Mujtaba will be equal to x – 15 years. Now let us move on to the second condition. Five years ago the age of Yasir will be equal to x – 5 years. Also, the age of Mujtaba five years ago will be x – 15 – 6 years = x – 21 years. As per the question, we have:

3(x – 21) = x – 5 or 3x – 63 = x – 5. Therefore we have: 2x = 58 and hence x = 29 years.
