Black Dahlia Hints

How do I come up with the correct answer?

  • Again, thanks to Olga Karkalas for this full rendition that results in the answer for the Math Problem shown on the wall of the Ferrin's Hill Cemetery crypt.

    3 stars = 2 skulls.  Therefore, 1 star = 2/3 skulls. 
    4 hanged men = 6 stars  (hanged men are referred to as men below).
    Replacing the stars with the skulls yields:   4 men = (6 x 2/3) skulls or 4 men = 4 skulls or 1 man = 1 skull.
    5 skulls = 2 men + 1.5 stars + 18 flames. 
    Replacing the men with the equivalent number of skulls gives us: 
    5 skulls = 2 skulls + 1.5 stars + 18 flames or
    3 skulls = 1.5 stars + 18 flames.
    We know that 1 star = 2/3 skulls. 
    Replacing the stars with skulls in the long equation, we obtain:
    3 skulls = (3/2 x 2/3) skulls + 18 flames, which reduces to 3 skulls = 1 skull + 18 flames.
    2 skulls = 18 flames.  1 skull = 9 flames.
    ? flames = 3 men = 3 skulls. 
    Replace skulls by flames. 
    ? flames = (3 x 9) flames. 
    ? is 27.
