This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

CRMO-Paper 3

- 7 years, 8 months ago

I took this paper. I was sitting behind Sreejato, and I got only questions 1, 2, and 4 right. I hope I make the cutoff!

- 7 years, 8 months ago

Isn't RMO a contest held in India? That's the impression that I had at least

edit: looking at the problems, I have to say problems 3 and 5 sure are tough.

- 7 years, 8 months ago

Yes, RMO is specifically for Indians. And problem 5 is pretty easy if you can find the recursion.

- 7 years, 8 months ago

hey....Sreejato in which class do u study????

- 7 years, 8 months ago

well 3rd one is simple. Menelaus theorem you see.... For maharashtra region... :P

- 7 years, 8 months ago

We are talking about CRMO Paper 3.

- 7 years, 8 months ago

I thought you live in USA. :O

- 7 years, 8 months ago

But I saw Cody entering ISI :P

- 7 years, 8 months ago

Have you been dreaming when you gave RMO? xD

- 7 years, 8 months ago

Dreaming that I had enough time to write up the solutions :|

- 7 years, 8 months ago

Oh!How I wish that you were seated next to me ,so that I could have a good shot>>>>Counterattack :p

- 7 years, 8 months ago

Downvoted.

- 7 years, 8 months ago

Any idea about the cutoff of paper 3 ?

- 7 years, 8 months ago

That's what I got! The problems weren't very hard, but the time limit (3 hours) put pressure on me. Apparently I solved the first four problems, but I won't get full credit for the third one, as I couldn't complete it (lack of time! >:( ). I had the fifth question on scratch, but didn't get the time to present it carefully. :'(

- 7 years, 8 months ago

Solved the fifth one now, only 4 lines more and my solution would have been complete >.< time was really a factor and that I did not have practice in solution writing was really a major fault from my side

- 7 years, 8 months ago

The fifth one was completely solved in my rough work. Unfortunately I won't get marks for it. -.-

- 7 years, 8 months ago

:| You could have atleast shown the recursive relation and give outline of the proof

- 7 years, 8 months ago

I had only like 1 minute left when I solved #4. :(

- 7 years, 8 months ago

Sreejato.. keno pakamo marish... :P emniteo peye jabi.. chap nis na.

- 7 years, 8 months ago

guarantee nei :(

- 7 years, 8 months ago

It was quite easy though.
