Video Summary

The transcript solves a logic problem about two kinds of monsters: one-eyed, four-legged monsters and three-eyed, two-legged monsters. Using the total of 9 eyes and 16 legs, it tests combinations systematically. Three three-eyed monsters would use all nine eyes but only six legs, so that doesn’t work. Two three-eyed monsters leave room for three one-eyed monsters, which gives exactly 9 eyes and 16 legs. Therefore, there are <strong>3 monsters with only one eye</strong>.
