Here You Go With Solution –

Among 9 balls 1 ball is Lighter, So first divide the 9 balls in 3 Groups as shown below

Now, let’s start weighing these balls in Groups

WEIGH Count – 1

Put Group A balls on one side and Group B balls on other side of two arm weighing scale.

Here we can find the Group in which the Lighter ball is present.

If Group A arm moves upward then Lighter ball is in Group A.

If Group B arm moves upward then Lighter ball is in Group B.

Else both the arms are balanced then Lighter ball is in Group C.

For next step, Suppose Group A arm moved upward and the Lighter ball is in Group A.

Weigh Count – 2

Now, put Ball 1 and Ball 2 on the two sides of weighing scale from Group A.

Here we can find the exact Lighter ball.

If Ball 1 arm moves upward then Lighter ball is Ball 1

If Ball 2 arm moves upward then Lighter ball is Ball 2

Else both the arms are balanced then Lighter ball is Ball 3

Similar Logic can be applied for other Groups.

So in minimum 2 weighs we can find the Lighter ball 🙂
