In Hindi, you have two main ways to ask this. The choice depends on who you're talking to.

For a friend, a peer, or someone younger, you would say: तुम इतने उदास क्यों हो? (Tum itne udaas kyon ho?). This is the informal and most common way.

If you are speaking to an elder, a stranger, or someone in a position of authority, you need to be more formal. In that case, you would ask: आप इतने उदास क्यों हैं? (Aap itne udaas kyon hain?).

Using "Aap" shows respect, which is a big deal in the culture.

There are a few kinds of money. The money we use today, like the US dollar, is called fiat money. It has value because the government says it does. We all just agree it's worth something. It is not backed by gold anymore.

A long time ago, people used commodity money. This was an actual item, like gold, silver, or even salt. These things were useful on their own. You could use them for other things, not just for buying stuff.

Also, a lot of money is just digital. It is the numbers in your bank account. Banks create this money when they give loans.
