Homework Equations

The Attempt at a Solution


first i am trying to express the equation
f=age of father
s=age of son
f=2s (father is twice as old as his son)
f-6=3(s-6) (6 years ago thrice as old as his son)

I got s=12 years old
and f=24 years old.
what does it mean by percentage here?

I don't know; it makes no sense.

I agree w/ your answer although it's just ridiculous (problem's fault, not yours) since that would mean the father had the son when he was 12 years old.

I agree w/ Ray that asking for a percentage makes no sense. Did you state the problem exactly as worded?

If the question is "what is the age of the son 6 years before..
s-6=6
then six would be correct answer?

In the book 6 is the answer for the original question(percentage)

yes exactly it is written like that. but the answer is six so i think it is asking for the age of son six years before

In that case it is REALLY a horribly worded problem.
