There are four three-digit numbers that share this property: the number itself, its double and its triple contain each digit from 1 to 9 exactly once. For example, 192 is one of them because 192, 384, 576 contain 1 to 9 each once. 273 is another one of them because 273, 546, 819 contain 1 to 9 each once. Can you find the other two numbers and calculate the product of these two numbers?Correct answers: 23

Supermodel Next Door
The middle-aged married couple finally moved into the condo of their dreams, but right next door to a very sexy fashion model. The husband had taken to borrowing this or that from their neighbour and it seemed to the wife that it always took him way too long to return.
One time the wife had had enough and actually pounded on the wall between the two apartments. There being no response she telephoned, only to get the answering machine. Finally she went to the model's door and just kept ringing the bell.
When the model answered, the wife fumed, "I would like to know why it is my husband takes so damn long to get something over here."
"Well sweetie," the model purred, "all these interruptions sure ain't helping none either."
