12 Balls Problem

Puzzle: We have 12 uniform balls.11 balls are
having same wait and remaining ball has different wait.
We will have a balance and have to use for three times
to find out the odd one.

Same puzzle we can extend to 13 balls other
rules are same. One interesting thing is this
13 balls problem is easier than 12 balls problem.


Note: The Odd Ball wait can be lower or higher then other balls

This is very good and complicated puzzle (At least for me).
I took one week to solve this puzzle. Try to solve the puzzle and
give your comments.

Perhaps more challenging than finding a solution to this problem is finding a simple way to explain the solution without using any diagrams or mathematical notation, so that it's easily graspable in one's head.
 
It's also possible in three weighings to determine whether the odd ball is heavier than the others or whether it's lighter.
 
You are right! But solving this puzzle is also very challenging!

It would be great! If you can explain the solution in simple way.
 
Easy
first divide into 6,6 and weigh
then take 4 and wiegh again in 2,2 pair if both equal then remaining 2 will have odd one if unequal then again u can separate it easily
