    Magic Star

    I've been trying to work this out for ages but it's driving me nuts!

    Any idea what belongs where the question mark is and why?

    If ? = 20, some consistency is found in the star. Notice:

    112\times 5 = 560

    35\times 16 = 560

    28\times ? = 560

    Also:

    \frac{112}{16}\times 5 = 35

    and

    \frac{112}{35}\times 5 = 16

    Applying a similar relation to 28 and ?

    If ? = 20 then:

    \frac{112}{28}\times 5 = 20

    and

    \frac{112}{20}\times 5 = 28

    It seems that 35 relates to 16 and 28 relates to ? while 112 and 5 relate to everything.

    5 * 112 = 560

    35 * 16 = 560

    28 * 20 = 560

    so ? = 20
