The SIM card itself is very cheap. I think it is only about 20 rupees. But you must buy a first recharge plan with it. This is the real cost. You cannot just buy the SIM alone.

The plans can change, but you should expect to pay around 150 to 300 rupees for your first month. This will give you data and calls. It is best to go to a proper BSNL office when you arrive. They will show you the available plans and help you choose the right one. The people there can make it easy.

The square root of 7 doesn't have a simple, clean answer. It is what they call an irrational number. This means the decimal numbers go on forever and they never repeat. So you can’t write the full number down.

My phone calculator says it is about 2.64575. For most things, like for a homework problem, using 2.65 is probably good enough. It just depends on how exact you need to be. But the real, full number is endless, you know? It's one of those special numbers in math.

It’s a fun Halloween tradition, mostly for kids. On October 31st, children dress up in costumes. They walk around their neighbourhood and knock on doors. When the door opens, they shout, "Trick or treat!" This is their way of asking for candy. The 'treat' is the candy they receive. The 'trick' is a playful, old-fashioned threat of a harmless prank if they don't get one. Honestly, it's all about getting the candy these days

PFB in an email usually means 'Please Find Below'. It is a way to tell the person to look further down the message. They are pointing you to something, like a file you need to open or some text they have pasted in.

To be honest, it is a bit of an old-fashioned phrase. You see it more in formal or corporate emails. I reckon it is becoming less common. These days, people often just write 'I've attached the document' or 'You can find the details below'. So, it just means 'look down here for the information'.

Hope that helps a bit! Cheers.
