Greek Anthology Book XIV: Metrodorus: 118

Arithmetical Epigram of Metrodorus
Myrto once picked apples and divided them among her friends; she gave the fifth part to Chrysis, the fourth to Hero, the nineteenth to Psamathe, and the tenth to Cleopatra, but she presented the twentieth part to Parthenope and gave only twelve to Evadne. Of the whole number a hundred and twenty fell to herself.

Solution
Let $n$ be the total number of apples.


 * $\dfrac n 5$ were given to Chrysis.


 * $\dfrac n 4$ were given to Hero.


 * $\dfrac n {19}$ were given to Psamathe.


 * $\dfrac n {10}$ were given to Cleopatra.


 * $\dfrac n {20}$ were given to Parthenope.


 * $12$ were given to Evadne.


 * $120$ were kept by Myrto.

Hence:

So the narrator started with $380$ apples, of which:


 * $76$ were given to Chrysis


 * $95$ were given to Hero


 * $20$ were given to Psamathe


 * $38$ were given to Cleopatra


 * $19$ were given to Parthenope

and as we know:


 * $12$ were given to Evadne

and $120$ were kept by Myrto.
