    Under The Cup Riddle

    Hint: Write down the possibilities. Remember that there are only three cups, so if the rightmost cup wasn't touched...
    The rightmost cup.

    The rightmost cup has a half chance of holding the coin, and the other cups have a quarter chance.

    Pretend that Os represent cups, and Q represents the cup with the coin.

    The game starts like this:

    OOQ

    Then your friend switches the rightmost cup with another, giving two possibilities, with equal chance:

    OQO
    QOO

    Your friend then moves the cups again, but doesn't touch the rightmost cup. The only switch possible is with the leftmost cup and the middle cup. This gives two possibilities with equal chance:

    QOO
    OQO

    Lastly, your friend switches the rightmost cup with another cup. If the first possibility shown above was true, there would be two possibilities, with equal chance:

    OOQ
    QOO

    If the second possibility shown above (In the second switch) was true, there would be two possibilities with equal chance:

    OOQ
    OQO

    This means there are four possibilities altogether, with equal chance:

    OOQ
    QOO
    OOQ
    OQO

    This means each possibility equals to a quarter chance, and because there are two possibilities with the rightmost cup having the coin, there is a half chance that the coin is there.

    Dropping Coconuts Riddle

    Hint: They break when dropped from the same height and they don't weaken from getting dropped.
    You could drop it at floor 1 first (because you start at floor 1). Then you would go to the floors: 14, 27, 39, 50, 60, 69, 77, 84, 90, 95, 99, and 100. Whatever floor your first coconut breaks at, go to the floor above the last floor the coconut survived and drop the second coconut from this floor. Then go up by one floor until the second coconut breaks and that is the lowest floor it will break at.

    Prince Age Riddle

    Hint:
    Current Future Past

    Princess x 2z (x+y)/2
    Prince y x z

    I then created three equations, since the difference in their age will always be the same.

    d = the difference in ages

    x y = d
    2z x = d
    x/2 + y/2 z = d

    I then created a matrix and solved it using row reduction.

    x y z

    1 -1 0 d
    -1 0 2 d
    .5 .5 -1 d

    It reduced to:

    x y z

    1 0 0 4d
    0 1 0 3d
    0 0 1 5d/2

    This means that you can pick any difference you want (an even one presumably because you want integer ages).

    Princess age: 4d
    Prince age: 3d

    Ages that work

    Princess:
    4
    8
    16
    24
    32
    40
    48
    56
    64
    72
    80

    Prince:
    3
    6
    12
    18
    24
    30
    36
    42
    48
    54
    60

    Missing Dollar Riddle

    Hint: Make a list of all of the people involved and how much money they ended up with/spent.
    The $9 paid by each guest accounts for the $2 that went to the bellhop. So rather than adding $27 to the $2 kept by the bellhop, the $27 accounts for the bellhops money. The $27 plus the $3 kept by the guests does add up to $30.
    Did you answer this riddle correctly?
    YES  NO
