9 balls are there one of them is of higher wt and remaining
all are of same. given is one weighing scale and you can
use it two times. How will you find the heavy ball in two
trials only.
Answer Posted / marx
1 Trial:
Take 3 set of 3balls and first compare any 2
set.They may are may not be equal.If thet are equal keep
these 2 sets aside and go to second trial with the 3rd set.
If they r not equal,go to second trial with the set of more
weight.
2 Trial:
Split the taken set of 3 balls in to 3 set of single
balls.Compare any one sets first.If they are equal we can
find the left out ball is of more weight.If not equal we
can find the most weight ball.
