    You can solve a question like that, but then you can't do a simple google. I am skeptical, Mr Prince Spinoza, very skeptical you figured it out! Tongue Smiley

    I'll call them person A, B and C and condoms 1 and 2.

    Person A has sex with the woman using both condoms, with 1 inside 2.
    Person B has sex with the woman using only the outer condom 2.

    Now the insides of condoms 1 and 2 are filthy.
    The outside of condom 1 is still clean.
    The outside of condom 2 is "contaminated" by the vagina. Smiley

    Person C has sex with the woman with condom 1 turned inside out inside condom 2.

    If I were person C, I would run down and buy a new condom.  Afro


    Nicely done.

    No idea HO. Though here's a problem:

    x1,x2,x3,...,xn for all n >= 3 satisfy the equations:

    x1 = 1 + (1 / x2), x2 = 1 + (1 / x3),..., xn-1 = 1 + (1 / xn)

    and also: xn = 1 + (1 / x1).

    Show that:

    i) x1,x2,x3,...,xn > 1

    ii) x2 - x3 = -(x2 - x3) / (x2x3)

    iii) x1 = x2 = x3 = ... = xn

    Hence find the value of x1.

    My solution to this works backwards, but I'm curious as to how you guys would approach this.

    Work out how much hair there was in 1 cm^2 of dog skin, then work out the total area of dog skin - and multiply the two.

    There's no other way of "working it out" apart from counting them out one by one.

    Or is there?
