Arithmetical Epigram of Metrodorus
- Mother, why dost thou pursue me with blows on account of the walnuts? Pretty girls divided them all among themselves.
- For Melission took two-sevenths of them from me,
- and Titane took the twelfth.
- Playful Astyoche and Philinna have the sixth and third.
- Thetis seized and carried off twenty,
- and Thisbe twelve,
- and look there at Glauce smiling sweetly with eleven in her hand.
- This one nut is all that is left to me.
Solution
Let $n$ be the total number of walnuts.
- $\dfrac {2 n} 7$ were taken by Melission.
- $\dfrac n {12}$ were taken by Titane.
- $\dfrac n 6$ were taken by Astyoche.
- $\dfrac n 3$ were taken by Philinna.
- $20$ were taken by Thetis.
- $12$ were taken by Thisbe.
- $11$ were taken by Glauce.
- $1$ remains to the poor narrator.
Hence:
\(\ds n\) | \(=\) | \(\ds \dfrac {2 n} 7 + \dfrac n {12} + \dfrac n 6 + \dfrac n 3 + 20 + 12 + 11 + 1\) | ||||||||||||
\(\ds \leadsto \ \ \) | \(\ds 84 n\) | \(=\) | \(\ds 24 n + 7 n + 14 n + 28 n + 84 \times 44\) | multiplying through by $84 = 7 \times 12$ and simplifying | ||||||||||
\(\ds \leadsto \ \ \) | \(\ds \paren {84 - 24 - 7 - 14 - 28} n\) | \(=\) | \(\ds 84 \times 44\) | |||||||||||
\(\ds \leadsto \ \ \) | \(\ds 11 n\) | \(=\) | \(\ds 84 \times 44\) | |||||||||||
\(\ds \leadsto \ \ \) | \(\ds n\) | \(=\) | \(\ds \dfrac {84 \times 44} {11}\) | |||||||||||
\(\ds \) | \(=\) | \(\ds 336\) |
So the narrator started with $336$ walnuts, of which:
- $96$ were taken by Melission
- $28$ were taken by Titane
- $56$ were taken by Astyoche
- $112$ were taken by Philinna
and as we know:
- $20$ were taken by Thetis
- $12$ were taken by Thisbe
- $11$ were taken by Glauce
and $1$ remains to the narrator.
$\blacksquare$
