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

Cure for a Cough
The owner of a drugstore walks in to find a guy leaning heavily against a wall with an odd look on his face.
The owner asks the clerk, "What's with that guy over there by the wall?"
The clerk says, "Well, he came in here at 7 A.M. to get something for his cough. I couldn't find the cough syrup, so I gave him an entire bottle of laxatives."
The owner says, "You idiot! You can't treat a cough with laxatives!"
The clerk says, "Oh yeah? Look at him-he's afraid to cough!"
