@saurav205 ,@scrabblerans is rt(3/2) + 1..analyse as 3 unit sphers and the 4th one on top of it..thn their centres as terahedron..find height..and circumsphere..thn its radius..thda jyada hi high hgya yr..mjhe bhi nhi hua tha
Haan maine wohi kiya...tetrahedron ko analyse karne mein (circumradius) wat lag gayi but...
Bus when typing the answer missed the rt3...answer to mera same hi hai...after cancelling... :) regards scrabbler
@scrabblerThe crew of an 8 member rowing team is to be chosen from 12 men of which 3 must row on one side only and 2 must row on the other side only. Find the no. of ways of arranging the crew with 4 members on each side? cant this be solved as:- 7!/2!*1! * (4!)^2

I guess the 4th sphere which is on top of the other 3 will go in the depression that is present...thoda height mein offset nai aayega kya??
correct me if I am wrong about the depression thing...cause when i visualize the entire setting toh depression toh dikhta hai...

No...because then you are assuming all the 3+2 = 5 are selected
What I mean is, suppose we have Lefties, Righties and Neutrals. L, R and N for short.
We have 3 L, 2 R and 7 N.
Now what you are doing is : Left side: LLLN Right Side : RRNN
But it could also be something like: Left side: LNNN Right Side : RNNN
I just need to choose 4 people who can row Leftie and 4 who can row Rightie...so the ambidextrous all rounders can replace the one-sided folks...
Toh we will get lots of cases (I guess this is that Arun Sharma problem, I seem to remember 7 cases banake kiya tha kabhi to ) regards scrabbler

When I was visualising it depression ho raha tha :( regards scrabbler
