If you list multiples of both 3 and 4:
3, 6, 9, 12, 15, 18, 21, 24, 27
4, 8, 12, 16, 20, 24, 28
If you add another 3 and 4 to 28 or 27 it would result in being greater than 30. The next number that’s a multiple of both that’s less than 30 but greater than 20 is 24
When you don’t get enough sleep after a while I would say about 2-3 days you will start hallucinating/ seeing things that are not really there. Then your brain will start to fall asleep while your body is still awake and moving, this can lead to death.
Depending on what disorder it is, I would say there is a 75 to 80% chance of it.
