775 (r+s)(s+t)(r+t)= (r+s+t)(rs+sr+st)-rst =a(a^2.b^3)- (-9ab)=k^2 implies a^2.b^2(ab-9)= k^2 implies ab-9=m^2 where m is an integer as k^2 is a perfect square given max value of a and b can be 31 and without loss of generality we take a<b, then we find b...

50 Let the radius of larger circle be a, smaller ones be 'b' and 'c'. Ans = pie(a^2-(b^2+c^2)) here we are only concerned with (a^2-(b^2+c^2))= (a^2 - ((b + c)^2 - 2bc) = 2bc as a=b+c Using intersecting chord theorem, 2bc= AC*BC/4= PC*CQ/4= 10*10/4 as dia...

SORRY GUYS I MEANT TO SAY ITS 60 SORRY DON'T USE 50 ITS 60!!

wrong...blunder..even for a simple graph with all vertices connected is given by n(n=1)/2 for 16 it is 15*8<<200000

wrong>...........and this is a brilliant problem,try to do it by yourself

copying .......brilliant

well the answer is 99

24 is correct but the fraction given is wrong.
