Re: Suggest some Books!!
@tanvir vaia, I would like books of both types. Specially ones that help understanding and extending textbook knowledge. Leisure Reading are also okay. But do consider that I haven't read much of books outside textbooks.

Re: dhaka div 2010
at first, $2^{6n+4}\equiv1 (mod 3)$
again, $5^{6n+4}\equiv1 (mod 3)$
so $2^{1024}+5^{1024}+1\equiv1+1+1=3 (mod 3)$
again, $5^{6n+4}\equiv1 (mod 3)$
so $2^{1024}+5^{1024}+1\equiv1+1+1=3 (mod 3)$

Re: dhaka div 2010
Yeah! I had also got it $3$. I think it would be $mod 3$ instead of $mod 9$.
Btw who understood that $S_n(x)$

Re: Combi probs from Moon vai's note...
bonji, thnx!!
btw , in soln of $3$ you wrote $(n-2)!\cdot(n-3)P2$
but shouldn't it be $(n-2)!\cdot(n-1)P2$?
