Four people are talking about Laotian's deposit. A said: "Laotian has at least 5,000 yuan deposit. " B said, "No, at least 10,000 yuan. " C said, "his deposit is less than 20,000. " Ding said: "Laotian's passbook has at least a hundred dollars. " Actually only one of them was right. From this, you can get:. ['A is right.', 'Ding is right.', "Laotian's deposit is not even 100 yuan.", "Laotian's deposit is between 5,000 and 20,000 yuan."]
