An eccentric casino owner decides that his casino should only use chips in $5 and $8 denominations. Which of the following amount cannot be paid out using these chips?
Choose one.
A) $34  B) $27  C) $31  D) $29  E) $24
Yes, the number of 5 or/and 8 dollar chips can be zero, however both being zero mean that the casino is paying out $0, which is not realistic.   Each option but B can be represented as the sum of a multiple of 5 and a multiple of 8:   A. $34 = 8*3 + 5*2   B. $31 = 8*2 + 5*3   C. $29 = 8*3 + 5*1   E. $24 = 8*3   Answer: $27.
