Propositiones ad Acuendos Juvenes by Alcuin of York: Problem $12$

A father, when dying, gave to his sons $30$ glass flasks,

of which $10$ were full of oil,

$10$ were half full,

and the last $10$ were empty.

Divide the oil and the flasks so that each of the $3$ sons receives equally of both glass and oil.

To each son will come $10$ flasks, as follows:

To one son, give him all the half full flasks.

To the other sons, give them $5$ full flasks and $5$ empty ones.

Some sources state that the flasks contained wine rather than oil.
