The actual solution to this riddle is to add correctly (correct time, correct person and correct location) from the bank point of view which in this case seems to be the problem: First day: $30 in the bank + $20 owner already withdrew = $50. Second day: $15 in the bank + ($15 + $20 owner already withdrew) = $50.
There is no missing dollar. That 2 is part of the 27. Mathemeatically, the misdirection is the refund. Event 1: $30 = $25 for hotel and $2 for bellhorn and $3 extra, to be refunded. Event 2: The 3 extra is refunded. This brings down the total paid. so -3 from both sides. $27= $25 for hotel and $2 for bellhorn.
The missing square puzzle is an optical illusion used in mathematics classes to help students reason about geometrical figures; or rather to teach them not to reason using figures, but to use only textual descriptions and the axioms of geometry. It depicts two arrangements made of similar shapes in slightly different configurations.
