wow, that's really great.
Just saw this post right now...
yes (as far as I know).
What is JEE? Joint Entrance Examinations?
JEE is my goal and its preparations are going in parallel, but now I am in class10 so my focus is more on boards.

This can happen until it has travelled 2root 3 in that direction. Say it happens n times then
But the ray has also hit A at the start so add one, but 'just' misses B at the end so take one off.
Hence the maximum number of reflections is 30.
I got 35 instead but I don’t know where I went wrong.
What a coincidence! This is the same question I encountered while taking the IIT JEE some years back. The answer is 30.
It is in post reply on the bottom, I can make a picture of it if you need it.
i am still not able to find the upload option in this section.
