Puzzle | Mislabeled Jars

There are 3 jars, namely, A, B, and C. All of them are mislabeled. The following are the labels of each of the jars:

• A: Candies
• B: Sweets
• C: Candies and Sweets (mixed in a random proportion)

You can put your hand in a jar and pick only one edible at a time. Determine the minimum number of eatables that must be picked to label the jars correctly.

Assume that the shape of the candies and sweets are identical and there is no way to differentiate them by touching alone.    

Check if you were right - full answer with solution below.  

Solution:

You have to pick only one eatable from jar C. Suppose the eatable is a candy, then the jar C contains candies only(because all the jars were mislabeled).

Now, since the jar C has candies only, Jar B can contain sweets or mixture. But, jar B can contain only the mixture because its label reads "sweets" which is wrong.

Therefore, Jar A contains sweets. Thus the correct labels are:

• A: Sweets.
• B: Candies and Sweets.

• C: Candies.
