Challenge:
Mr. Anderson is 36 years old. His son is 6 years old. After how many years Mr. Anderson’s age will become exactly 2.5 times his son’s age?
The Absolute Best Book to Challenge Your Smart Student!
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.
