How does half a dozen remain? Question

+2
−0

If from six you take nine, and from nine you take ten,

(You youths, now the mystery explain;)

And if fifty from forty be taken, there then

Shall just half a dozen remain.


The above puzzle appeared in the book:
“Rational amusement for winter evenings” (1821) by John Jackson.

Probably not correct...

This sounds too far-fetched a solution to be correct, but I'll give it a try:

Type out the numbers you got as Roman numerals:

VI (6) IX (9) 40 (XL) = VI IX XL

  • Remove IX (9) = VI XL
  • Remove X (10) = VI L
  • Remove L (50) = VI
  • VI (6) remains.

I find this puzzle clever because to solve it,

Spoiler 1

you need to interpret some of the given numbers as English words and some as Roman numerals.

So the solution is:

Then I wasn't that far off after all. Except this solution is even more far-fetched than mine :) (1 comment)

I'm not sure if this is the intended solution, but it seems to fit.

Explanation

If you remove the letters of each word from the word it is "taken" from, there are 2 letters remaining in each of the 3 cases, a total of 6 (half a dozen) letters remaining.

  • Start with SIX and remove the letters of NINE to leave SX.
  • Start with NINE and remove the letters of TEN to leave IN (TEN only has 1 N so only 1 is removed from NINE).
  • Start with FORTY and remove the letters of FIFTY to leave OR.
