Illustrious got it right
In a remore monastery in Tibet live 53 monks. They have made a vow of silence and poverty. Every day, they gather to pray, and then they can all see each other.
Then, a doctor from outside tell them they have some sick in their community. The sick monks have a dot in their forehead, but they cannot see it (they don't have any mirror), and they cannot tell each other (they vowed not to communicate).
The doctor tells them as soon as a sick realize he's sick, he should isolate himself.
After 5 days, all the sick monks are isolated. How many are they?
Note 1: They are all supposed to be bright enough to make the correct logical deduction when required
Note 2: No monk catch the disease during the 5 days : all the sick monks were sick from the start.
