    Age Of Three Daughters Riddles

    Hint:
    3, 3, and 8. The only groups of 3 factors of 72 to have non-unique sums are 2 6 6 and 3 3 8 (with a sum of 14). The rest have unique sums:

    2 + 2 + 18 = 22
    2 + 3 + 12 = 18
    2 + 4 + 9 = 15
    3 + 4 + 6 = 13

    The house number alone would have identified any of these groups. Since more information was required, we know the sum left the answer unknown. The presence of a single oldest child eliminates 2 6 6, leaving 3 3 8 as the only possible answer.

    Two Solid Metal Pillars

    Hint:
    The twig and the rock were simply distractions used to divert you from the real answer. Forget I ever mentioned them. All you need to do is fill the space between you with enough rope that it makes a pile so big that you can walk across it to the other pillar (remember I said you had an unlimited supply of rope).

    Three People In A Room

    Hint:
    Simple strategy: Elect one person to be the guesser, the other two pass. The guesser chooses randomly 'green' or 'blue'. This gives them a 50% chance of winning.


    Better strategy: If you see two blue or two green hats, then write down the opposite color, otherwise write down 'pass'.

    It works like this ('-' means 'pass'):

    Hats: GGG, Guess: BBB, Result: Lose
    Hats: GGB, Guess: --B, Result: Win
    Hats: GBG, Guess: -B-, Result: Win
    Hats: GBB, Guess: G--, Result: Win
    Hats: BGG, Guess: B--, Result: Win
    Hats: BGB, Guess: -G-, Result: Win
    Hats: BBG, Guess: --G, Result: Win
    Hats: BBB, Guess: GGG, Result: Lose

    Result: 75% chance of winning!

    Just to reiterate the hint, if you knock down a single pin, for example at the far left of the back row, then repeat the same identical shot on your second throw, you'll score 0 points for your second throw (because there's no pin there anymore), but it's not a gutter ball as the shot did not enter the gutter.
