Harold is twice as old as Jack, who is three years older than Dan. If Harold's age is five times Dan's age, how old in years is Jack?

Verified Answer :

Dan's age is x.
Jack is three years older than Dan, so his age is x+3.
Harold is twice as old as Jack, so his age is 2(x+3).

Harold's age is five times Dan's age.
\(2(x+3)=5x \\ 2x+6=5x \\ 6=5x-2x \\ 6=3x \\ \frac{6}{3}=x \\ x=2 \\ \\ x+3=2+3=5\)

Jack is 5 years old.
