(#M40000151) BOOK QUESTION Keep an EYE

There are 9 coins. Out of which one is odd one i.e weight is less or more. How many iterations of weighing are required to find odd coin?

Solution

It requires a maximum of 4 weighings. Divide the 9 balls into sets of 3 each. Let them be set1, set2 and set3. Weigh set1 and set2 against each other. If they weigh equal, then set3 contains odd coin. Otherwise, weigh set1 against set3. If they weigh equal, set2 contains odd coin. If in both cases, they do not weigh equal, then set1 contains odd coin. Now, we have identified set with defective coin in maximum 2 weighings. Repeat this process on individual coins of the found set. This requires a max of 2 more weighings. Hence, the odd coin can be found in a maximum of 4 weighings at all times.
