You should word it as "five times as old" to remove ambiguity.

@ DEEM That is true. In russian it was called "Where is the father" so my searches for duplicate proved worthless

Well, first I have to solve the math problem, I guess.
Let $x$ equal Jimmy's age.
This means $x+21$ is the mother's starting age. In 6 years, Jimmy will be $x+6$ and his mother will be $x+27$.
So, $(x+6)*5 = x+27$
$5x+30 = x+27$
$5x + 3 = x$
$4x = -3$
$x = -3/4$
Yeah, I see where this is going. Jimmy is exactly -9 months old, which means his father is right where his mother is, most likely.

Easy math:
Let $x$ represent Jimmy's age.
Let $y$ represent Jimmy's mother's age.
We can convert this into two equations:
$x+21=y$
$5*(x+6) = y+6$
Substituting the first equation into the second equation via isolated y:
$5x+30=x+21+6$
Subtract x and 30 from both sides of the equation:
$4x = -3$
Jimmy is -3/4 years old. This is the length of a pregnancy (9 months).
Jimmy's father is currently sleeping with his mother as he is being conceived.
