Question 218793: A father is 32 years old and his daughter is 2 years old. He is now 16 times as old as his daughter. In how many years will he be only 4 times as old? Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! The big thing to notice here is that the difference
in their ages never changes
Let = Father's age
Let = Daughter's age (always)
This is a ratio problem, so (4 times as old)
And, rewriting:
Multiply both sides by
The Father will be 40 when he's 4 times as old as his Daughter
and that will be in 8 years since he's 32 now.
Notice that the fact that he was 16 times as old as his Daughter
when he was 32 was just thrown in to confuse you
