This is how it made sense to me.

When the statement says. The boys have spend 4 dollars each to a total of $12 PLUS David's share is equal to 14, is wrong.
Because we can't add David's share to the $12; David's share comes from the $12 and is part of it.

You can say the same thing as ridicilous as it sounds: each have spend 4 dollars to a toal of $12 plus the $10 that the store keeper has for the ladder equals to $22. Where did the extra $7 go ? well 2 went to David. So where did the other $5 go ? you see what i mean ?

Arnold, Bryan and Colin payed 12 coins for a 1O coin ladder (3x4) because they employed a middleman who charged a 2 coin commission.
Its just a good thing that David had a conscience otherwise they might have been left thinking that 15 coins was good price for a 10 coin ladder and "by the way where's that ladder?"

There is no missing coin. The question itself is flawed. You don't take the amount contributed by each party (3 x 4 = 12) and ADD the two that David kept! You take the amount contributed by each party (3 X 4 = 12) and SUBTRACT the two kept by David which leaves the 10 (ten) coins that were spent on the ladder. The math is all good, its the question that is illogical.

Spoiler for My method:


Edit: (5:16 PM, 1/24/12)

Another thing that it could be, is because the three men spent a total of 12 coins, 10 for the ladder, 2 for David. The total the three men spent should include the 2 coins for David.
