Hey Guys, RMO online Mock Test is going to be started on 28th September 2015 at 10:00 P.M. (I.S.T) at http://rmoonlinetest.weebly.com . Read the rules and regulations on this page. Please pass this message to all ASAP.

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.

Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Sorry Surya. I wasn't able to send the solutions because I was preparing for pre-RMO and other class tests.. Can you accept them now?
If no then,just accept them and give me only marks and your solutions also. Reply ASAP!!

@Surya Prakash I went to the website you mentioned and entered my solution. I even previewed it and my latex looks to be fine but I am having problem converting it to pdf. Can you please give me some suggestions? Are there any other alternatives to enter the solution?

@Surya Prakash hi man. I may not be able to post the solutions very formally because of a high amount of school work. I can tell them to you informally, like on chat. Sorry :/

On the brighter side, you'll have one paper less to check!

@Surya Prakash
–
I am sending mail of my answers to the email id from which i recieved the paper . Please accept it as i received the paper yesterday itself.

@Surya Prakash I have sent you pictures of my solution since you were not able to view my previous solution. Please confirm if it is alright as soon as possible as there are only a few hours to go!!
