That depends what the age of his father is.
Let, son's age be 'x'. So, Father's present age is 4x. Now, by the question, after 20 years, fathers, age=4x+20 and son's age =x+20 and, twice son,s age= father's age so, 2(x+20)=4x+20 2x+40=4x+20 2x=20 x=10 So, son's age is 10 years and father's age is 4x or 40 years.
Well, well, well, looks like we've got a little math puzzle on our hands. Let's break it down: if adding 2 years to the boy's age makes him a quarter of his father's age, and five years ago the father was one year less than ten times his son's age, then the boy is currently 10 years old and the father is 40. Math never lies, darling.
Age of the father is 20. Pretty young to be a father. Son is 8 years old. The equations are as folllows: x-2 = 3 (y-2) 2x = 5y Cheers
Easy he is 55. Becuase: 22*2=44+11=55
