Sam is x years old. Sam's uncle is four times as old as Sam will be in 5 years. Find the present age of Sam's uncle

1 answer

Sam's present age ----- x
Sam's age 5 years from now ---- x+5
Present age of Sam's uncle ---- 4(x+5)

Now you need some more information to find a definite answer.

e.g. if x=5
then Sam is now 5, and his uncle is 40
if x= 8, Sam is now 8 and his uncle is 52
etc , within a reasonable domain of their ages.
