TED-Ed: Can you solve the fish riddle? - Steve Wyborney

In this video, you are the cargo director on the SS Buoyant, tasked with rescuing endangered fish tanks lost during a storm. With limited resources, you must determine the number of missing tanks using sector analysis and logical deduction. By analyzing the number of sharks and fish, and using a table to compare data, you deduce that there are 13 tanks with 39 fish, each tank containing 3 fish. Successfully retrieving the tanks, you save the species from extinction.
