I, (almost) 17F recently received around 10,000 rupees, (approx 137.80 US Dollar) what are the best ways I can invest this money? context below.

For reference, I am Indian, and here, 10,000 rupees means a lot.

It was a national examination, and I scored the highest in my region, and received around 18,000 rupees. however, my dog was ill, so I had decided to pay from my earnings, and now I have 10,000 rupees that I do not want to spend on materialistic things that give me joy for like a short while.

I am looking for a long term investment. Currently, I am in the last year of my school, and 2022, I'll be moving out to college. I am looking forward to invest any prize money I get this year too, in the same way I am trying to invest this 10,000 if it works out. i come from a relatively financially well off family, and I'm not in any dire need of money right now, but I know I will be when I'm in my 20s, as I would like to be financially independent as soon as I can.

i am thinking about stocks, mutual funds, or SIPs. but I really don't know. it's my first earning and I want to do something worthwhile with it.

I will really appreciate some advice, thank you!
