Answer Posted / muhammad akram
hi i m ch akram from kabirwala,,,,,,,,,,
total balls=8
separate 2 balls from them
put 3 balls from remaining 6 in one side of scale and 3 in
other side. now there r two possibilites
1- that both sides equal
2- not equal
if both sides r equal then put the initially separated 2
balls in two sides of scale that we find the less weight
ball
if both sides r not equal then take the 3 balls of less
weight AND separate one ball from these 3 balls and put
remaining 2 balls in two sides of scale, if agan the scale
is equal then the 3rd separated ball in of less weight,and
if the scale is not equal u will find the less weight ball
directly
