A guy was asked to specify his age in years. He said, “Take my age 3 years hence, multiply it by three and subtract thrice of my age 3 years ago and you will know my age.” What was the age of that guy?
5 years
6 years
16 years
18 years
Explanation:
Lets assume his current age is ‘x’.
His age 3 years from now: (x+3)
His age 3 years earlier: (x-3).
As per what is stated, his current age is - 3(x+3) - 3(x-3)
therefore, solve x= 3x + 9 - 3x + 9
The answer is x = 18
