and if they don balance.. its one one of the 3 in any one.. and if that also does not balance replace one with the third one

3rd posibility wud be 3 -3 in first trial, they dont balance and then 1-1 and they balance and then 3rd one with any of the remaining ones..

am i right fiery shadow??

say the balls are ABCDEFGH
1st weigh –> 2nd weigh –> 3rd weigh
————————————————————————–
(ABC == DEF) –> (G == A) –> (H (G == A) –> (H > A)……H is heavier
————————————————————————–
(ABC == DEF) –> (G (G > A)…………………..G is heavier
————————————————————————–
(ABC > DEF) –> (ADG == BEH) –> (C == A)……F is lighter
(ABC > DEF) –> (ADG == BEH) –> (C != A)……C is heavier
————————————————————————–
(ABC > DEF) –> (ADG > BEH) –> (A == C)……E is lighter
(ABC > DEF) –> (ADG > BEH) –> (A != C)……A is heavier
————————————————————————–
(ABC > DEF) –> (ADG (D == C)……B is heavier
(ABC > DEF) –> (ADG (D != C)……D is lighter
————————————————————————–
(ABC (ADG == BEH) –> (C == A)……F is heavier
(ABC (ADG == BEH) –> (C != A)……C is lighter
————————————————————————–
(ABC (ADG > BEH) –> (D == C)……B is lighter
(ABC (ADG > BEH) –> (D != C)……D is heavier
————————————————————————–
(ABC (ADG (A == C)……E is heavier
(ABC (ADG (A != C)……A is lighter

Place 4 balls on either side.. Take the 4 which weighs on the lesser side.. seperate into twos… weigh the same.. Again select the two which weighs less.. weigh the two.. You have got the ball with the minimum weight. The reverse process if the ball weighs more than the others.

You are assuming that the 8th ball is heavy whereas it can also be lighter you have to find both the defective ball and also if it is heavier or lighter

None of you got the right answer yet… (You have to mail the detailed solution at gurus.comments[at]gmail[dot]com )
