There are 100 people from different nationality, gender, profession etc in a ballroom are taken as captives by an underground gang.

Each of captives are given 5 dollar bills.

And said

After 30 minutes, all of you will be categorized into 3 groups of people.

1) group with 0 dollars

2) group with 5 dollars

3) group with more than 5 dollars

Once categorized,

  • We will Kill all those belongs to group 1.
  • We will chop down the hand and legs of those belongs to group 2.
  • We will gift 5 million dollars to those who belongs to group 3 and will be set free

How do you make it so you end up in the 3rd group?

Nb:You cannot fight with others to get their money. The gang will kill those who are fighting instantly.

    $\begingroup$ How do you get more or less money? For instance do they bet or something like that? $\endgroup$ – Beastly Gerbil Oct 19 '16 at 6:45

Do nothing special.
1. Each captive has 5 dollars.
2. All of them together are considered a group (group of 100 captives).
3. The group they make has 500 dollars (100 people with 5 dollars each).

So you belong to a "group with more than 5 dollars". Nothing to worry about.

Well it doesn't say what you do in that 30 minutes, but if you want to end up with more than 5 dollars then you could:

1. Nick someone's money

2. Leave the ballroom, go home and get more money before coming back, or simply start with more money

3. Make a bet with someone of 5 dollars that you will end in group 2. Then at the end you will be placed in group 2 but the person has to give you their 5 dollars so you will be moved to group 3.

Plan 3 is the sort of answer you were probably looking for more, although I would probably go with the Plan 1 :P

Since it is so open ended, I would:

Offer shares of the reward I assume I will earn for being in group 3 for a dollar, so anyone willing to give me money to upgrade my grouping gets a cut of the reward. If there isn't any reward for being in group 3 (rendering this solution invalid), I'm going home to do something more productive with my time.
