The correct answer is 14.
Let x be the number of years that Mr. Anderson’s age will become 2.5 times of his son’s age. Therefore:
36 + x = 2.5 (6 + x) → 36 + x = 15 +2.5 x → 21 = 1.5x → x = 14
In 14 years, Mr. Anderson will be 50 years, (36 + 14 = 50) which is 2.5 times of his son who will be 20 years.
