Today, due to urgent matters, Huy spent all 72,000 VND and had 6 bills left in his wallet. What are the denominations of the bills Huy spent?"

After reading the question, the candidate calculated and gave the answer that Huy spent 1 50,000 VND bill, 1 20,000 VND bill and 2 1,000 VND bills. However, this answer was not correct, the remaining candidates did not press the bell to answer.
