Euler Piruleta Vs. Tartufo

Tartufo has many non-admirable qualities… he is not only a ruffian and a cheater, but also a words-twister and ruthless person. Even more, he uses his domain of cult language to seduce both naïve men and women to be his lovers.

But don’t worry! Euler Piruleta has proven not to be a naïve person… pffiuuu! Anyway, Tartufo has used a Rajoy-Merkel software to hack into Euler Piruleta’s bank account and has stolen every single euro from it. He would only return the money if our hero manages to solve this simple-in-appearance problem.

A woman is 21 years elder than her son. In 6 years, the mother’s age will be five times his son’s.
Question: where is the woman’s boyfriend?

You have many algebra skills but Euler has none… help him to solve this tricky challenge! Don’t be daunted by the solution, it may seem wrong, but if you think carefully about its possible interpretation, you may be able to answer the question!

CLUES:

1) Don’t forget that in 6 years, both the woman and the son will be 6 years older

2) Remember that we are working with YEARS, so the solutions are expressed in YEARS. This means that you may have to interpret/translate one of the solutions to get the answer to the question… where is the women’s boyfriend?

As usual, send me your solutions by e-mail, and explain briefly how did you get to that result. Deadline: February the 17th. There's also a printable version.

As I promised, you can download now the solutions to the "Extra Exercises"!!
