Forum rules
Please don't post problems (by starting a topic) in the "X: Solved" forums. Those forums are only for showcasing the problems for the convenience of the users. You can always post the problems in the main Divisional Math Olympiad forum. Later we shall move that topic with proper formatting, and post in the resource section.

Re: Please Post the Problems of 2013
একটা ধনাত্মক পূর্ণসংখ্যাকে ফ্যান্টাবুলাস বলা হবে যদি তার আগে অন্তত একটা ধনাত্মক পূর্ণসংখ্যা ফ্যান্টাবুলাস সংখ্যা থাকে।সর্বমোট কয়টা ফ্যান্টাবুলাস সংখ্যা আছে?

Re: Please Post the Problems of 2013
What sort of problem is this? This is an inconsistent definition! If x, x/2, x/4, x/8, ... etc are fantabulous, then this sequence gives infinitely many such numbers. If there is no such number, then there are 0 such numbers. This shows that the problem is inconsistent.Prosenjit Basak wrote:একটা ধনাত্মক সংখ্যাকে ফ্যান্টাবুলাস বলা হবে যদি তার আগে অন্তত একটা ধনাত্মক ফ্যান্টাবুলাস সংখ্যা থাকে।সর্বমোট কয়টা ফ্যান্টাবুলাস সংখ্যা আছে?

Oho....I made a mistake . Every fantabulous must be an integer.That's the main thing. And once again sorry for the inconsistent definition.nayel wrote:What sort of problem is this?

Re: Please Post the Problems of 2013
oh forgot to tell another thing.Fantabulous is a imaginary kind of number. Don't be confused.It's not a complex
number but a imagination. Fantastic + Fabulous = Fantabulous
number but a imagination. Fantastic + Fabulous = Fantabulous

That is very crucial. In this case it is a very nice problem.Prosenjit Basak wrote:Oho....I made a mistake . Every fantabulous must be an integer.That's the main thing. And once again sorry for the inconsistent definition.
