Episode #10 of the course The world’s most compelling logic puzzles by John Robin

Welcome to the last lesson!

To close the course, let’s imagine a real-world workplace problem, where \$1,000 is on the line. It goes like this: There are three jars. One has apples, another has oranges, and the last one has a mixture of apples and oranges. They have labels:

• apples

• oranges

• apples and oranges

50% of the time, all three of the jars are mislabeled.

This is how you start your first day at work in a new shipping warehouse. Your employer explains this is a common problem from the assembly line and wants to find out how to ensure the right lids are in place in as short a time as possible. She was impressed that on your resume, you mentioned you have studied logic puzzles, so she has given you the following incentive:

If you can find out what’s in each jar by not lifting the lids at all, you’ll get a \$1,000 bonus. If you can find out what’s in each jar every time by lifting one lid, you’ll get a \$100 bonus. Two or more, you’ll just get \$10.

How much money can you make, and what exactly do you have to do in order to make it?

Try it yourself, then click the button below and compare.

I hope you’ve enjoyed our tour. Though we’re done, the world of logic puzzles is vast, and you can continue to explore these on your own. I’ve equipped you by showing how to apply your skill in the areas of mathematics and visual, linguistic, and conceptual thinking. Now you can go out and become your own logic puzzle master and teach your friends as well!
