I will do the prize presentation and announce the solution in one single post coz I dun want to create too many posts haha
So probably you have to wait for 7 days for the payout of my post, and then I will know how much is the prize pool for prize presentation

ya coz the payout time is 7 days, hope you can understand :( otherwise I have to make 4 posts for each competition: announcement, question, answer and prize presentatin

Can you just tell me the answer plz? xD

as I remember the answer should be 19, not at home though so can't check my rough work...
