    Shoe Man Whistle

    Hint:
    The third equation has a term with a pair of whistles. The last line involves a single whistle.

    Furthermore, the man in the second and third lines are wearing a whistle, but the man in the last line is not wearing a whistle. Presumably the value of the whistle should be accounted for to get the correct answer.

    The pictures can be translated into the following equations:

    shoes + shoes + shoes = 30
    shoes + (man + whistle) + (man + whistle) = 20
    (man + whistle) + 2(whistles) + 2(whistles) = 13
    shoes + (man) x (whistle) = ?

    From the first equation we can solve for the shoes value:

    shoes + shoes + shoes = 30
    3(shoes) = 30
    shoes = 10

    We can then solve the second equation for the (man + whistle) value:

    shoes + (man + whistle) + (man + whistle) = 20
    10 + 2(man + whistle) = 20
    2(man + whistle) = 10
    man + whistle = 5

    Then we solve the third equation for the whistle:

    (man + whistle) + 2(whistles) + 2(whistles) = 13
    5 + 4(whistles) = 13
    4(whistles) = 8
    whistle = 2

    We also need to solve for the value of the man:

    man + whistle = 5
    man + 2 = 5
    man = 3

    Now we can evaluate the final expression, remembering the order of operations that multiplication should be evaluated before addition:

    shoes + (man) x (whistle) = ?

    10 + 3 x 2
    = 10 + 3 x 2
    = 10 + 6
    = 16

    Playing With A Book Riddle

    The Older Twin Brother

    Hint:
    It's all because the clocks went back. Samuel Peterson was born on 1.39am on Sunday, November 6. His brother Ronan, meanwhile, was born 31 minutes later, but by then daylight saving hours had ended, and the clock was turned back one hour.

    So while Ronan was in a sense born at 2:10 am on November 6, his official time of birth is actually 1:10 am.

    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).
