There are 8 billiard balls, and one of them is slightly
heavier, but the only way to tell was by putting it on a
weighing scale against another. What's the fewest number of
times you'd have to use the scale to find the heavier ball?

Answer / mahesh t
first take 6 balls from 8 balls
from those 6 divide 3 and 3 check it in weighing scale if it
equals weight remaining 2 balls and you get the hevier
ball....of not equals take the 3 balls which is hevier from
those weighing with 6 balls then take 2 balls from those 3
balls and weight if equals the remaining one is hevier
and final you can know the hevier ball within 2 times
