You have nine coins that exactly look same. One of the coins is of slightly less weight than the other eight coins which have same weight. You have a balance. Without using any weights, how can you determine which is the lighter coin? You have to carry out exactly 2 weighings only.

pahle 3-3 weight karo, isse pata chal jayegaa kee kis 3 me halke wala hai..

aur phir 1-1 (us 3 ke batch me se) weight karne se pata chal jayega kee konsa halka hai.
