Learn Dutch: Raad eens: zit het geld in de kluis? - Take a guess: is the money in the safe?

Raden means to guess, so raad is the command form. Dutch speakers often add eens (literally 'once') to soften a command. It makes the phrase sound friendly and conversational, translating well to 'take a guess' rather than a strict order.

Why does the sentence use zit (sits) instead of is for the money?

Dutch typically uses posture verbs (zitten, liggen, staan) to describe where things are located, rather than just using zijn (to be). Because the money is enclosed inside a container (the safe), Dutch naturally uses zitten to describe its position.

Since this lesson is about the place word er, how would I answer this question with 'Yes, it is in there'?

To replace the specific location (in de kluis), you use the locative pronoun er (there) and combine it with the preposition in. The natural answer becomes Ja, het zit erin (Yes, it sits in-there).
