## 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?
