All answers in this thread are wrong.
The real solution:
-Each person paid $10 at the beginning
-Each person was refunded $1 which brings their total to $9 out of pocket, which is a combined total of $27
-The thief has $2 in his pocket, which the combined total out of pocket is $29
How can this be?
The solution is simple, the bill cannot be divided into 3 (using common currency), thus, someone in the group must pay more, so the "missing dollar"
is the extra one person must pay to settle the bill.
