A party is being held at a local mansion. The host is very rich and his success is because of one thing — his famous recipe for Spaghetti!
The only guests that may attend are people who correctly reply to the guard at the door.
Here's where you come in. You and a friend are trying to steal this recipe. You sneak by and listen to the passwords.
The first guest arrives. The guard stops him and says: 22! The guest after a couple of seconds answers: 4! The guard allows him to pass.
It's time for the second guest. The guard yells: 136! The guest starts to think about it and comes out with 81. The guard nods and lets him pass.
Your friend has been spotted so he's forced to give an answer. You hear the guard say 44 and your friend, surprisingly, joins the party with his magic 22.
It's now your turn, because you can't be beaten by your friend. After the guard tells you 94, what will you answer to join your friend, already drunk and dancing with elephants?
Tomorrow (18-11) will be my birthday! I will be [answer] years old! It's up to you to find out how old I'll be!
Another guest arrives. The guard says 11 and the guest answers 1 and comes in with ease!
