Divide the 9 Balls in three groups each with three balls. Lets name the group as A B and C

Step1: Now Weight Group A and B

If Both are Equal then C will be the Group with the Ball of Different Weight

If Both are not Equal the Group with the More Weight will have the Ball with the Most Weight

Step2: Take any two balls from Most Weight Group

If both the balls are equal then the third ball is the Odd one

If both are not equal the one with more weight is the odd one

Hope I am clear in making you all understanding it !!!
