    Not the key but possibly a clue.

    The Sumerians, Babylonians, Chinese, Persians even the Greeks (sometimes)
    used base 60 systems. 60 is such an accommodating number. Why is that?

    That's your clue.
    60 has 12 divisors — 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30 and 60.

    I get the thing about 60 but I still can't see the answer to the puzzle

    OK. I really didn't think this was hard.

    Lowest common multiples (LCM)

    I have to say number theory is my least favorite subject.

    Like all these things , the answer is obvious when you see it.
    Thanks for the puzzle.
    I'll have to find something else to think about to put me to sleep when I go to bed now!!

    1. How can you add 4.5 to 9.55 and get 2.25?
    2. If 1=5, 2=25, 3=325, 4=666 what does 5 equal?
    3. The Post Office only accepts cuboid parcels, it defines length at
    the longest dimension, width as the second longest and depth as
    the third. They do not accept parcels exceeding a length of 120cm,
    or a width of 40cm or a depth of 30cm.
    What is the longest item I can send?
    4. What is the next ...[text shortened]... om and found 60 pennies, I gave them
    to the bank and they gave me 25 shiny pennies in return. Why?
    1. Add four and a half hours to 9:55

    2. If 1=5 then 5=1

    3. A stick of length 130 will fit in a box 30x40x120

    4. Lowest common multiples of numbers up to 1,2,3,4,5,6. Next is 420.

    5. T time

    6. Roman numerals.

    7. A hole.

    8. He was President before he got assassinated.

    9. Total length of chain is 3m which means a circle of diameter 6m.

    10. For a short time after decimalisation in UK old pennies could be banked. 60d = 25p
