If a father is twice as old as his son. six years ago father was thrice as old as his son. Find the percentage.
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?
