The minimum number of weighs to find the odd ball is 4.

• Divide the 10 balls into 3 groups of 3, 3, and 4.

• Compare the weights of the two groups of 3 balls.

• If the weights are equal, the odd ball is in the group of 4.

• If the weights are unequal, the odd ball is in the lighter group of 3.

• Divide the lighter group of 3 balls into individual balls and compare their weights.

• The odd ball will be identified in the 4th weigh.
